Half of remote workers feel vulnerable to growing cyber attacks

New research has revealed that almost half (49%) of employees working remotely feel vulnerable online due to the insecurity of the company laptops and PCs they are using to connect to corporate networks.

1,550 UK employees working from home during the pandemic were surveyed to better understand the security issues they've faced while working remotely.

The survey found that 42 percent of respondents received suspicious emails while 18 percent have dealt with a security breach while working from home. Of those who suffered a cyberattack, over half (51%) believed it was because they clicked on a malicious link and 18 percent believed an infected attachment was responsible.

Additionally, 42 percent of respondents reported that someone else in their household had experienced a hack of their social media accounts during the lockdown.

Many remote workers given no cyber security training

Two in three remote workers have not received any cyber security training in the past 12 months, according to a new report.

Based on a poll of 2,000 remote workers in the UK, the report states that more than three quarters (77 percent) are unconcerned about cyber security. Further, more than six in ten said they use personal devices when working from home, which poses a distinct threat to business data.

The report highlights the dangers associated with working from home and the fact cyber criminals are capitalising on the coronavirus outbreak to infect unwitting victims with malware.

With most businesses transitioning to remote working in response to lockdown measures, IT and security teams have been left with a network of unsecured, often naive workers who are easy prey for various forms of attack - especially phishing.

Spear-phishing campaign compromises executives at 150+ companies

A cyber crime group operating since mid-2019 has breached the email accounts of high-ranking executives at more than 150 companies, cyber-security firm Group-IB reported today.

The group, codenamed PerSwaysion, appears to have targeted the financial sector primarily, which accounted for more than half of its victims; although, victims have been recorded at companies active across other verticals as well.

PerSwaysion operations were not sophisticated, but have been extremely successful, nonetheless. Group-IB says the hackers didn't use vulnerabilities or malware in their attacks but instead relied on a classic spear-phishing technique.

They sent boobytrapped emails to executives at targeted companies in the hope of tricking high-ranking executives into entering Office 365 credentials on fake login pages.

Microsoft: Ransomware gangs that don't threaten to leak your data steal it anyway

Just because ransomware attackers haven't threatened to leak your company's data, it doesn't mean they haven't stolen it, Microsoft warns.

And human-operated ransomware gangs – typically associated with multi-million dollar ransom demands – haven't halted activity during the global coronavirus pandemic.

In fact, they launched more of the file-encrypting malware on target networks in the first two weeks of April than in earlier periods, causing chaos at aid organizations, medical billing companies, manufacturing, transport, government institutions, and educational software providers, according to Microsoft.

Google Confirms New Security Threat For 2 Billion Chrome Users

Google has warned of yet more security vulnerabilities in Chrome 81, which was only launched three weeks ago.

Google has confirmed two new high-rated security vulnerabilities affecting Chrome, prompting yet another update since the release of Chrome 81 on April 7. These new security threats could enable an attacker to take control of an exploited system, which is why the U.S. Cybersecurity and Infrastructure Security Agency (CISA) has advised users to apply that update now.

These popular antivirus tools share a major security flaw

More than two dozen popular antivirus solutions contain a flaw that could enable hackers to delete files, trigger crashes and install malware, according to a new report.

Popular antivirus solutions such as Microsoft Defender, McAfee Endpoint Security and Malwarebytes all feature the bug, which is described as “trivial” to abuse.

The report refers to the shared vulnerability as “symlink race” – the use of symbolic links and directory junctions to link malicious files to legitimate counterparts. This all occurs in the short space of time between an antivirus scanning and deleting a file.

"Make no mistake about it, exploiting these flaws was pretty trivial and seasoned malware authors will have no problem weaponising the tactics outlined in this blog post," said the report.

Hackers are exploiting a Sophos firewall zero-day

Cyber-security firm Sophos has published an emergency security update on Saturday to patch a zero-day vulnerability in its XG enterprise firewall product that was being abused in the wild by hackers.

Sophos said it first learned of the zero-day on late Wednesday, April 22, after it received a report from one of its customers. The customer reported seeing "a suspicious field value visible in the management interface."

After investigating the report, Sophos determined this was an active attack and not an error in its product.

This sophisticated new Android trojan threatens hundreds of financial apps

Researchers have discovered a sophisticated new Android trojan that bypasses security measures and scrapes data from financial applications.

First identified in March, the EventBot banking trojan abuses Android’s accessibility features to harvest financial data and intercept SMS messages, allowing the malware to circumvent two-factor authentication.

According to the firm responsible for the discovery, EventBot targets over 200 financial applications, spanning banking, money transfer and cryptocurrency wallet services.

Affected applications include those operated by major players such as HSBC, Barclays, Revolut, Paypal and TransferWise - but many more are thought to be at risk.

Microsoft Office 365: US issues security alert over rushed remote deployments

The US Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA) has published security advice for organizations that may have rushed out Office 365 deployments to support remote working during the coronavirus pandemic.

CISA warns that it continues to see organizations that have failed to implement security best practices for their Office 365 implementation. It is concerned that hurried deployments may have lead to important security configuration oversights that could be exploited by attackers.

"In recent weeks, organizations have been forced to change their collaboration methods to support a full 'work from home' workforce," CISA notes in the new alert.

Financial sector is seeing more credential stuffing than DDoS attacks

The financial sector has seen more brute-force attacks and credential stuffing incidents than DDoS attacks in the past three years according to a report published this week.

Statistics about attacks carried out against banks, credit unions, brokers, insurance, and the wide range of organizations that serve them, such as payment processors and financial Software as a Service (Saas).

The report's findings dispel the notion that DDoS attacks are one of today's most prevalent threats against the financial vertical.

The report states that brute force attacks, credential stuffing, and all the other account takeover (ATO) attacks have been a much bigger threat to the financial sector between 2017 and 2019. This includes all the ATO variations such as:

· Brute-force attacks - attackers try common or weak username/passwords pairs (from a preset list) to brute-force their way into an account

· Credential stuffing - attackers try username/password pairs leaked at other sites

· Password spraying - attackers try the same password, but against different usernames

This buggy WordPress plugin allows hackers to lace websites with malicious code

Security researchers have identified a flaw in the Real-Time Find and Replace WordPress plugin that could allow hackers to lace websites with malicious code.

The affected plugin affords WordPress users the ability to edit website code and text content in real-time, without having to go into the backend - and reportedly features on over 100,000 sites.

The exploit manipulates a Cross-Site Request Forgery (CSRF) flaw in the plugin, which the hacker can use to push infected content to the website and create new admin accounts.

Zoom Gets Stuffed: Here’s How Hackers Got Hold Of 500,000 Passwords

At the start of April, the news broke that 500,000 stolen Zoom passwords were up for sale. Here's how the hackers got hold of them.

More than half a million Zoom account credentials, usernames and passwords were made available in dark web crime forums earlier this month. Some were given away for free while others were sold for as low as a penny each.

Researchers at a threat intelligence provider obtained multiple databases containing Zoom credentials and got to work analysing exactly how the hackers got hold of them in the first place.

Sophisticated Android Spyware Attack Spreads via Google Play

The PhantomLance espionage campaign is targeting specific victims, mainly in Southeast Asia — and could be the work of the OceanLotus APT.

A sophisticated, ongoing espionage campaign aimed at Android users in Asia is likely the work of the OceanLotus advanced persistent threat (APT) actor, researchers said this week.

Dubbed PhantomLance by Kaspersky, the campaign is centered around a complex spyware that’s distributed via dozens of apps within the Google Play official market, as well as other outlets like the third-party marketplace known as APKpure.

The effort, though first spotted last year, stretches back to at least 2016, according to findings released at the SAS@home virtual security conference on Tuesday.

Skype phishing attack targets remote workers

Remote workers have been warned to take extra care when using video conferencing software after a new phishing scam was uncovered.

Researchers from a security firm have revealed hackers are using emails pretending to be from Skype, the popular Microsoft-owned video calling tool, in order to trick home workers into handing over their login details.

Criminals could then use these logins to access corporate networks to spread malware or steal valuable information.

Over half of organisations expect remote workers to increase the risk of a data breach

Apathy towards cyber security remains one of the biggest challenges for businesses.

The majority of UK’s IT decision-makers believe remote workers will expose their businesses to the risk of a data breach.

This is according to a new report which claims the awareness of the issue has been “steadily growing” over the last three years.

While the report does not offer definitive explanations for the rise, it cites increased remote working due to the coronavirus as a contributing factor.

The percentage of employees intentionally putting data at risk dropped slightly (from 47 to 44 percent), but apathy continues to be a “major problem”.

However, remote working appears to have forced IT decision-makers to pay closer attention to security.

Almost all (96 percent) respondents acknowledged risks associated with BYOD policies and a significant portion of those (42 percent) only allow the use of pre-approved gear (up from 11 percent last year).

This change is “crucial”, as lost and misplaced devices are now the second biggest data breach cause (24 percent), behind intentionally putting data at risk (33 percent) and ahead of mishandling corporate data.

Trickbot Named Most Prolific #COVID19 Malware

Notorious malware Trickbot has been linked to more COVID-19 phishing emails than any other, according to new data from Microsoft.

The Microsoft Security Intelligence Twitter account made the claim on Friday.

“Based on Office 365 ATP data, Trickbot is the most prolific malware operation using COVID-19 themed lures,” it said. “This week’s campaign uses several hundreds of unique macro-laced document attachments in emails that pose as messages from a non-profit offering a free COVID-19 test.”

Microsoft has been providing regular updates through the current crisis as organizations struggle to securely manage an explosion in home working while cyber-criminals step up efforts to exploit stretched IT security teams and distracted employees.

Microsoft Issues Out-Of-Band Security Update For Office, Paint 3D

Microsoft has released an out-of-band security update for Microsoft Office, Office 365 ProPlus and Paint 3D. The applications are affected by multiple Autodesk vulnerabilities that, if exploited, could enable remote code execution.

The flaws, all rated “important” in severity, are tied to six CVEs stemming from Autodesk’s library for FBX, a popular file format format that supports 3D models. This library is integrated into certain Microsoft applications

1,000 may be hit by CISI website fraud attack

The CISI has launched an investigation after a website attack resulted in 1,000 customers and members being exposed to the risk of credit card fraud.

The professional body with 45,000 members says some members have reported “fraudulent activity” on their cards following a payment transaction on the CISI website.

The organisation, which provides the Certified Financial Planner and Chartered Wealth manager designations, has launched a probe with help from its insurers and KPMG.

The CISI has contacted 5,785 customers that processed a payment transaction through its website between 1 February 2020 and 15 April 2020.

It said not all of these have seen “fraudulent activity” but it anticipates about 1,000 have been exposed to a risk of fraud.

Here's a list of all the ransomware gangs who will steal and leak your data if you don't pay

Starting with late 2019 and early 2020, the operators of several ransomware strains have begun adopting a new tactic.

In an attempt to put additional pressure on hacked companies to pay ransom demands, several ransomware groups have also begun stealing data from their networks before encrypting it.

If the victim -- usually a large company -- refuses to pay, the ransomware gangs threaten to leak the information online, on so-called "leak sites" and then tip journalists about the company's security incident.

Companies who may try to keep the incident under wraps, or who may not want intellectual property leaked online, where competitors could get, will usually cave in and pay the ransom demand.

While initially the tactic was pioneered by the Maze ransomware gang in December 2019, it is now becoming a widespread practice among other groups as well.

Clop, Doppenpaymer, Maze, Nefilim, Nemty, Ragnarlocker, Revil (Sodinokibi), Sekhmet, Snatch

Hackers have breached 60 ad servers to load their own malicious ads

A mysterious hacker group has been taking over ad servers for the past nine months in order to insert malicious ads into their ad inventory, ads that redirect users to malware download sites.

This clever hacking campaign was discovered last month and appears to have been running for at least nine months, since August 2019.

Hackers have targeted advertising networks running old versions of the Revive open-source ad server. Hackers breach outdated Revive servers and silently append malicious code to existing ads.

Once the tainted ads load on legitimate sites, the malicious code hijacks and redirects site visitors to websites offering malware-laced files -- usually disguised as Adobe Flash Player updates.

GCHQ calls on public to report coronavirus-related phishing emails

GCHQ is asking members of the public to report suspicious emails they have received amid a wave of scams and hacking attacks that seek to exploit fear of Covid-19 to enrich cybercriminals.

The National Cyber Security Centre, a branch of the intelligence agency, has launched the suspicious email reporting service with a simple request of the public: forward any dubious emails to report@phishing.gov.uk, and the NCSC’s automated scanning system will check for scam emails and immediately remove criminal sites.

Hackers exploit bug to access iPhone users’ emails

Hackers have devised a way to install malicious software on iPhones without getting the victim to download an attachment or click on any links.

Cybersecurity researchers have discovered a bug in the phone’s email app that hackers may have been exploiting since January 2018. It enables hackers to access all emails on a phone, as well as remotely modify or delete them.

Typically, an attack on a phone requires a user to download the malware, such as clicking on a link in a message or on an attachment. Yet in this case, hackers send a blank email to the user. When the email is opened, a bug is triggered that causes the Mail app to crash, forcing the user to reboot it. During the reboot, hackers could access information on the device.

The hack is virtually undetectable by victims due to the sophisticated nature of the attack and Apple’s own security measures, which often make investigating the devices for potential vulnerabilities a challenge, experts claim.

FBI Sees Cybercrime Reports Increase Fourfold During COVID-19 Outbreak

Instances of cybercrime appear to have jumped by as much as 300 percent since the beginning of the coronavirus pandemic, according to the FBI. The bureau’s Internet Crime Complain Center (IC3) said last week that it’s now receiving between 3,000 and 4,000 cybersecurity complaints every day, up from the average 1,000 complaints per day the center saw before COVID-19 took hold.

While much of this jump can be attributed to America’s daily activities increasingly moving online — newly remote workers unaware of basic security measures or companies struggling to keep externally-accessed systems secure, for example — the FBI says a lot of the increased cybercrime is coming from nation states seeking out COVID-19-related research.

309 million Facebook users’ phone numbers found online

Last weekend, researchers came across a database with 267m Facebook user profiles being sold on the Dark Web.

Looking to verify the records and add them to the firm’s breach notification service, the researchers bought it, for the grand total of £500.

That works out to USD $540 — or about 0.0002 cents — per record. The records held Facebook users’ IDs, which are unique, public numbers associated with specific accounts that can be used to figure out an account’s username and other profile info. The records also included full names, email addresses, phone numbers, timestamps for last connection, relationship status and age.

Fortunately, there were no passwords exposed, but the breach still forms a perfect tool kit for an email or text phishing campaign that looks like it’s coming from Facebook itself. If enough users get fooled into clicking on spearphishers’ rigged links, it could lead to the exposure of even more, and more valuable, data.

Google Issues Warning For 2 Billion Chrome Users

Google just gave its two billion Chrome users a brilliant (if long overdue) upgrade, but it doesn’t mask all of the controversial changes, security problems and data concerns which have worried users about the browser recently. And now Google has issued a new critical warning you need to know about.

Chrome has a critical security flaw across Windows, Mac and Linux and it urges users to upgrade to the latest version of the browser (81.0.4044.113). Interestingly, at the time of publication, Google is also keeping the exact details of the exploit a mystery.

Zoom announces 5.0 update with tougher encryption and new security features

Zoom has today announced its new 5.0 update, bringing robust new security features including AES 256-bit GCM encryption.

Zoom says that AES 256-bit GCM encryption will "raise the bar for securing our users' data in transit", providing "confidentiality and integrity assurances on your Zoom Meeting, Zoom Video Webinar and Zoom Phone Data." The systemwide enablement of this new security standard will take place on May 30.

Zoom has also introduced a new security icon, where it has grouped its security features in one place within Zoom's meeting menu bar. It has also introduced more robust host controls, including a 'report a user' feature. Waiting rooms now default to on, as do meeting passwords and cloud recording passwords. Zoom has also introduced a new data structure for linking contacts within larger organizations. Previously, a Zoom feature designed to group users by domain name had seen thousands of random users grouped together, sharing lots of information with strangers.

Temporary coronavirus hospitals face growing cybersecurity risks

The coronavirus outbreak has led to a series of temporary medical facilities opening across the U.S., most of which will use remote-care devices without the proper protection against hackers. Because of their remoteness and the overall uncertainty that pandemic’s created, cybersecurity at these temporary hospitals has fallen to the wayside and risks are at an all-time high.

Further complicating matters, most of these temporary units are highly dependent on connected medical devices to facilitate remote care. This leaves these hospitals open to hackers stealing patients’ personal health information via these connected devices.

Fortunately, there are a number of steps health care organizations can take to protect their remote facilities. Not only should organizations ensure their software is up to date and fully patched, but they should also consider enabling two-factor authentication for every account that’s granted access to the remote center’s system.

To assist with securing these remote health care locations, Microsoft has expanded the availability of its AccountGuard security service program. Currently offered at no cost to health care providers on the front lines of the coronavirus outbreak, Microsoft’s AccountGuard service helps targeted organizations protect themselves from ongoing cybersecurity threats.

For this week's Cyber Tip Tuesday video Bruce explains the basics of ransomware

Welcome to this week's Tip Tuesday, this week Bruce talks about the basics of Ransomware. Ransomware is malicious software, or malware, that criminals install on your computer to encrypt your data and lock down your computers. The criminal then demands payment in exchange for giving you back your information.

Welcome to this week's Tip Tuesday, this week Bruce talks about the basics of Ransomware.

Ransomware is malicious software, or malware, that criminals install on your computer to encrypt your data and lock down your computers. The criminal then demands payment in exchange for giving you back your information.

This usually starts with your employee clicking on a link in an email or an attachment. The malware then spreads across your network and corrupts your computers. In some cases, it will also take a copy of your data and send it to the criminal.

One of the classic ways to reduce the risk of successful ransomware is to take a regular back up of your information, so that you can revert to that copy and continue with your business. But now criminals are threatening to publish your confidential information online if you don't pay, which can severally damage your reputation and potentially destroy your business.

So the best thing is to avoid being a victim by implementing a range of controls, including stopping the criminal entering your system.

60 second video version of this week’s flash briefing

More top companies ban Zoom following security fears

As usage of Zoom rises amidst the global pandemic, more companies are telling their staff to stay off the video conferencing service due to security concerns.

Among the latest organisations to block the use of Zoom are German industrial giant Siemens, which sent out an internal circular urging its employees to not use the tool for video conferencing, with Standard Chartered Bank also issuing a similar note to its staff.

The latter has told employees to avoid Google Hangouts, which has also emerged as another popular teleconferencing application in recent weeks.

Over 500,000 Zoom accounts sold on hacker forums, the dark web

Over 500,000 Zoom accounts are being sold on the dark web and hacker forums for less than a penny each, and in some cases, given away for free.

These credentials are gathered through credential stuffing attacks where threat actors attempt to login to Zoom using accounts leaked in older data breaches. The successful logins are then compiled into lists that are sold to other hackers.

Some of these Zoom accounts are offered for free on hacker forums so that hackers can use them in zoom-bombing pranks and malicious activities. Others are sold for less than a penny each.

Microsoft April 2020 Patch Tuesday fixes 3 zero-days – 2 of which being actively exploited, 15 critical flaws

Microsoft's April 2020 Patch Tuesday fell this week, and with everything going on, it is going to be particularly stressful for Windows administrators.

With the release of the April 2020 security updates, Microsoft has released fixes for 113 vulnerabilities in Microsoft products. Of these vulnerabilities, 15 are classified as Critical, 93 as Important, 3 as Moderate, and 2 as Low.

Of particular interest, Microsoft patched three zero-day vulnerabilities, with two of them being seen actively exploited in attacks.

Users should install these security updates as soon as possible to protect Windows from known security risks.

Hackers Are Selling a Critical Zoom Zero-Day Exploit for £400,000

Hackers are selling two critical vulnerabilities for the video conferencing software Zoom, one for Windows and one for MacOS that would allow someone to hack users and spy on their calls.

The two flaws are so-called zero-days, and are currently present in Zoom’s Windows and MacOS clients, according to three sources who are knowledgeable about the market for these kinds of hacks. The sources have not seen the actual code for these vulnerabilities, but have been contacted by brokers offering them for sale.

Zero-day exploits or just zero-days or 0days are unknown vulnerabilities in software or hardware that hackers can take advantage of to hack targets. Depending on what software they’re in, they can be sold for thousands or even millions of dollars.

Phishing kit prices skyrocketed in 2019 by 149%

The average price of a phishing kit sold on cybercrime markets has gone up in 2019 by 149% according to new findings released this week based on analysis of ads posted on known cybercrime markets and hacking forums.

The average price for phishing kits sold on the cybercrime underground in 2019 has skyrocketed to $304 on average last year, up from only $122 recorded in 2018.

Phishing kit prices rose despite an increase in the number of kit sellers (up by 120%) and the number of phishing kit ads (doubled in 2019).

Of the 16,200 phishing kits identified and tracked in 2019, the most targeted login pages were for Amazon, Google, Instagram, Office 365, and PayPal.

Amazon and PayPal are known targets of phishing operations, as access to both accounts can allow hackers to make fraudulent transactions with victims' funds.

A Sinister New Botnet Could Prove Nearly Impossible To Stop

Security researchers have discovered an emerging threat that they fear could be nearly unstoppable. This growing botnet has already managed to enslave nearly 20,000 computers.

It is known as DDG, and it’s been lurking in the shadows for at least two years. DDG was first discovered in early 2018.

Back then the nascent botnet had control of just over 4,000 so-called zombies and used them to mine the Monero cryptocurrency. Much has changed since then.

Today’s incarnation of DDG isn’t just five times larger. It’s also much more sophisticated.

One of its distinguishing features is its command and control system. Most botnets are designed around a client/server model. Infected machines listen for instructions from the servers and then carry out their orders.

MSC Data Centre Closes Following Suspected Cyber-Attack

A container shipping company has said malware could be to blame for the closure of one of its data centres last week.

The Mediterranean Shipping Company (MSC) took to Twitter on Good Friday to report a network outage issue affecting the website msc.com, which was still down at time of writing.

The incident, which is thought to have occurred on Thursday, April 9, also brought down the shipping company's myMSC portal.

A message posted from the Twitter account MSC Cargo on April 10 stated: "We are sorry to inform you that http://MSC.com and myMSC are currently not available as we've experienced a network outage in one of our data centers. We are working on fixing the issue."

As a result of the outage, self-service tools for making and managing bookings on MSC ships have ceased to be operational. Alternative booking platforms are available, and customers can still book via email and over the phone.

UK NCSC and US CISA issue joint Advisory: COVID-19 exploited by malicious cyber actors

A joint advisory was put out from the United Kingdom’s National Cyber Security Centre (NCSC) and the United States Department of Homeland Security (DHS) Cybersecurity and Infrastructure Security Agency (CISA) relating to information on exploitation by cyber criminal and advanced persistent threat (APT) groups of the current coronavirus disease 2019 (COVID-19) global pandemic. It includes a non-exhaustive list of indicators of compromise (IOCs) for detection as well as mitigation advice.

Travelex paid $2.3M in Bitcoin to get its systems back from hackers

Travelex paid hackers $2.3 million worth of Bitcoin to regain access to its computer systems after a devastating ransomware attack on New Year’s Eve.

The London-based company said it decided to pay the 285 BTC based on the advice of experts, and had kept regulators and partners in the loop throughout the recovery process.

Although Travelex, which manages the world’s largest chain of money exchange shops and kiosks, did confirm the ransomware attack when it happened, it hadn’t yet disclosed a Bitcoin ransom had been paid to restore its systems.

Travelex previously blamed the attack on malware known as Sodinokibi, a ‘Ransomware-as-a-Service’ tool-kit that has recently begun publishing data stolen from companies that don’t pay up.

Travelex‘ operations were crippled for almost all of January, with its public-facing websites, app, and internal networks completely offline. It also reportedly interrupted cash deliveries to major banks in the UK, including Barclays and Lloyds.

At the time, BBC claimed that Travelex‘ attackers had demanded $6 million worth of Bitcoin to unlock its systems.

Zoom sets up CISO Council and hires ex-CSO of Facebook to clean up its privacy mess

The ongoing coronavirus pandemic has seen people relying on work collaboration apps like Teams and Slack to talk to others or conduct meetings. Zoom, in particular, has seen incredible growth over the past few weeks but it came at a cost. The company has been under a microscope after various researchers discovered a number of security flaws in the app. To Zoom’s credit, the company responded immediately and paused feature updates to focus on security issues.

The company announced that it’s taking help from CISOs to improve the security and patch the flaws in the app. Zoom will be taking help from CISOs from HSBC, NTT Data, Procore, and Ellie Mae, among others. Moreover, the company is also setting up an Advisory Board that will include security leaders from VMware, Netflix, Uber, Electronic Arts, and others. Lastly, the company has also asked Alex Stamos, ex-CSO of Facebook to join as an outside advisor. Alex is a well-known personality in the cybersecurity world who left Facebook after an alleged conflict of interest with other executives about how to address the Russian government’s use of its platform to spread disinformation during the 2016 U.S. presidential election.

Researchers discover IoT botnet capable of launching various DDoS attacks

Cyber security researchers have found a new botnet comprised of more than a thousand IoT devices, capable of launching distributed denial of service (DDoS) attacks.

According to a report, researchers have named the botnet Dark Nexus, and believe it was created by well-known malware developer greek.Helios - a group that has been selling DDoS services and botnet code for at least the past three years.

Analysing the botnet through a honeypot, the researchers found it is comprised of 1,372 bots, but believe it could grow extremely quickly.

Dark Nexus is based on Mirai and Qbot, but has seen some 40 iterations since December 2020, with improvements and new features added almost daily.

Microsoft: Cyber-Criminals Are Targeting Businesses Through Vulnerable Employees

Microsoft has warned that cyber-criminals are preying on people’s vulnerable psychological states during the COVID-19 pandemic to attack businesses. During a virtual press briefing, the multinational technology company provided data showing how home working and employee stress during this period has precipitated a huge amount of COVID-19-related attacks, particularly phishing scams.

Working from home at this time is very distracting for a lot of people, particularly if they are looking after children. Additionally, many individuals are in a stressful state with the extra pressures and worries as a result of COVID-19. This environment is providing new opportunities for cyber-criminals to operate.

“We’re seeing a significant increase in COVID-related phishing lures for our customers,” confirmed Microsoft. “We’re blocking roughly 24,000 bad emails a day with COVID-19 lures and we’ve also been able to see and block through our smart screen 18,000 malicious COVID-themed URLs and IP addresses on a single day, so the volume of attacks is quite high.”

Stolen Zoom account credentials are freely available on the dark web

Loved, hated, trusted and feared in just about equal measure, Zoom has been all but unavoidable in recent weeks. Following on from a combination of privacy and security scandals, credentials for numerous Zoom account have been found on the dark web.

The credentials were hardly hidden -- aside from being on the dark web. Details were shared on a popular forum, including the email address, password, meeting ID, host key and host name associated with compromised accounts.

Shadow IT Represents Major #COVID19 Home Working Threat

Rising threat levels and remote working challenges stemming from the COVID-19 pandemic are putting increased pressure on IT security professionals, according to new data.

A poll of over 400 respondents from global organisations with over 500 employees was conducted to better understand the current challenges facing security teams.

It revealed that 71% of security professionals had reported an increase in security threats or attacks since the start of the virus outbreak. Phishing (55%), malicious websites (32%), malware (28%) and ransomware (19%) were cited as the top threats.

These have been exacerbated by home working challenges, with 95% of respondents claiming to be under new pressures.

Top among these was providing secure remote access for employees (56%) and scalable remote access solutions (55%). However, nearly half (47%) of respondents complained that home workers using shadow IT solutions represented a major problem.

These challenges are only going to grow, according to the research.

'Unkillable' Android malware gives hackers full remote access to your phone

Security experts are warning Android users about a particularly nasty strain of malware that's almost impossible to remove.

A researcher has written a blog post explaining how the xHelper malware uses a system of nested programs, not unlike a Russian matryoshka doll, that makes it incredibly stubborn.

The xHelper malware was first discovered last year, but the researcher has only now established exactly how it gets its claws so deeply into your device, and reappears even after a system restore.

Although the Google Play Store isn't foolproof, unofficial third party app stores are much more likely to harbour malicious apps. App-screening service Google Play Protect blocked more than 1.9 million malware-laced app installs last year, including many side-loaded or installed from unofficial sources, but it's not foolproof.

xHelper is often distributed through third-party stores disguised as a popular cleanup or maintenance app to boost your phone's performance, and once there, is amazingly stubborn.

Decade of the RATs (Remote Access Trojan): Novel APT Attacks Targeting Linux, Windows and Android

BlackBerry researchers have released a new report that examines how five related APT groups operating in the interest of the Chinese government have systematically targeted Linux servers, Windows systems and Android mobile devices while remaining undetected for nearly a decade.

The report comes on the heels of the U.S. Department of Justice announcing several high-profile indictments from over 1,000 open FBI investigations into economic espionage as part of the DOJ’s China Initiative.

The BlackBerry report, titled Decade of the RATs: Cross-Platform APT Espionage Attacks Targeting Linux, Windows and Android, examines how APTs have leveraged the “always on, always available” nature of Linux servers to establish a “beachhead” for operations. Given the profile of the five APT groups involved and the duration of the attacks, it is likely the number of impacted organisations is significant.

The cross-platform aspect of the attacks is also of particular concern in light of security challenges posed by the sudden increase in remote workers. The tools identified in these ongoing attack campaigns are already in place to take advantage of work-from-home mandates, and the diminished number of personnel onsite to maintain security of these critical systems compounds the risks. While the majority of the workforce has left the office as part of containment efforts in response to the Covid-19 outbreak, intellectual property remains in enterprise data centres, most of which run on Linux.

Most large organizations rely on Linux to run websites, proxy network traffic and store valuable data. While Linux may not have the visibility that other front-office operating systems have, it is arguably the most critical where the security of critical networks is concerned. Linux runs nearly all of the top 1 million websites, 75% of all web servers, 98% of the world’s supercomputers and 75% of major cloud service providers (Netcraft, 2019, Linux Foundation, 2020).

Bot traffic fueling rise of fake news and cybercrime

The coronavirus pandemic has disrupted daily life around the world and the WHO recently warned that an overabundance of information about the virus makes it difficult for people to differentiate between legitimate news and misleading information.

At the same time, EU security services have warned that Russia is aggressively exploiting the coronavirus pandemic to push disinformation and weaken Western society through its bot army.

A cyber security firm has been using its bot manager to monitor internet traffic in an attempt to track the “infodemic” that both the WHO and EU security services have issued warnings on.

According to the data, bots have upped their game and organisations in the social media, ecommerce and digital publishing industries have experienced a surge in bad bot traffic following the coronavirus outbreak.

The bots have been found to be executing various insidious activities including spreading disinformation, spam commenting and more. In February, 58.1 percent of bots had the capability to mimic human behaviour. This means that they can disguise their identities, create fake accounts on social media sites and post their masters' propaganda while appearing as a genuine user.

GFSC warns over increased risk of fraud and cyber crime

The GFSC has put out a warning to regulated firms on the Island around increased likelihood of fraud and other cyber crimes as a result of the COVID-19 pandemic.

The Commission has stated that they expect licensees to apply effective controls, including having suitable controls to prevent cybercrime.

Cyber-Attacks Up 37% Over Past Month as #COVID19 Bites

Online threats have risen by as much as six-times their usual levels over the past four weeks as the COVID-19 pandemic provides new ballast for cyber-attacks.

Analysis of UK traffic figures for the past four weeks compared to the previous month noted a sharp uptick in malicious activity.

Hacking and phishing attempts were up 37% month-on-month, while on some days, there were between four- and six-times the number of attacks it would usually see.

Cybercrime spikes during coronavirus pandemic, says Europol

Just like everyone else in the face of a pandemic, criminals seem to be staying home — but they're just turning to different methods to make a buck.

That's the message from a new Europol report out this week, which reveals that criminals are adapting to exploit the global chaos.

While many police departments are reporting a lull in physical crime, other types of crime are having a heyday — and those numbers are only expected to increase.

Europol identified cybercrime, fraud, counterfeit goods and organised property crime as categories of particular concern.

Cybercriminal group mails malicious USB dongles to targeted companies

Security researchers have come across an attack where an USB dongle was mailed to a company under the guise of a Best Buy gift card. This technique has been used by security professionals during physical penetration testing engagements in the past, but it has very rarely been observed in the wild. This time it's a known sophisticated cybercriminal group who is likely behind it.

The attack was analysed after a US company in the hospitality sector received the USB sometime in mid-February.

The package contained an official-looking letter with Best Buy's logo and other branding elements informing the recipient that they've received a $50 gift card for being a regular customer. "You can spend it on any product from the list of items presented on an USB stick," the letter read. Fortunately, the USB dongle was never inserted into any computers and was passed along for analysis, because the person who received it had security training.

Top Email Protections Fail in Latest COVID-19 Phishing Campaign

Threat actors continue to capitalize on fears surrounding the spread of the COVID-19 virus through a surge in new phishing campaigns that use spoofing tactics to effectively evade Proofpoint and Microsoft Office 365 advanced threat protections (ATPs), researchers have found.

New phishing attacks were discovered that use socially engineered emails promising access to important information about cases of COVID-19 in the receiver’s local area.

The emails evade basic security checks and user common sense in a number of ways, to circumvent detection and steal the user’s Microsoft log-in credentials, he said. They also don’t include specific names or greetings in the body of the messages, suggesting they are being sent out to a broad target audience, according to the report.

Zoom Phishers Register 2000 Domains in a Month

Over 2000 new phishing domains have been set up over the past month to capitalise on the surging demand for Zoom from home workers, according to new data.

The report analysed data from a threat hunting system since the start of the year, and found 3300 new domains had been registered with the word “Zoom” in them.

The vast majority of these (67%) were created in March, as the COVID-19 pandemic forced lockdowns in multiple European countries and across parts of the US.

With surging levels of interest in Zoom and other video conferencing apps, comes renewed scrutiny from cyber-criminals.

Nearly a third (30%) of the new “Zoom” websites spotted activated an email server which indicates these domains are being used to facilitate phishing attacks.

Across-the-board increase in DDoS attacks of all sizes

There has been a 168% increase in DDoS attacks in Q4 2019, compared with Q4 2018, and a 180% increase overall in 2019 vs. 2018, according to a report.

DDoS attacks grew across all size categories increase in 2019, with attacks sized 5 Gbps and below seeing the largest growth. These small-scale attacks made up more than three quarters of all attacks the company mitigated on behalf of its customers in 2019.

In 2019, the largest mitigated threat, at 587 gigabits per second (Gbps), was 31% larger than the largest attack of 2018, while the maximum attack intensity observed in 2019, 343 million packets per second (Mpps), was 252% higher than that of the most intense attack seen in 2018.

However, despite these higher peaks, the average attack size (12 Gbps) and intensity (3 Mpps) remained consistent year over year. The longest single, uninterrupted attack experienced in 2019 lasted three days, 13 hours and eight minutes.

Though the number of attacks increased significantly across all size categories, small-scale attacks (5 Gbps and below) again saw the largest growth in 2019, continuing the trend from the previous year.

Cybersecurity insurance firm Chubb investigates its own ransomware attack

A notorious ransomware gang claims to have successfully compromised the infrastructure of a company selling cyber insurance.

The Maze ransomware group says it has encrypted data belonging to Chubb, which claims to be one of the world’s largest insurance companies, and is threatening to publicly release data unless a ransom is paid.

The announcement by the cybercrime gang was published on Maze’s website, where it lists what it euphemistically describes as its “new clients”.

Maze’s normal modus operandi is to compromise an organisation, steal its data, infect the network with its ransomware, and post a pre-announcement on its website as a warning to the corporate victim that if they do not pay a ransom their stolen data will be published on the internet.

Ransomware Payments on the Rise

More ransomware victims than ever before are complying with the demands of their cyber-attackers by handing over cash to retrieve encrypted files.

New research published this week shows that both the number of ransomware attacks and the percentage of attacks that result in payment have increased every year since 2017.

The report states 62% of organisations were victimised by ransomware in 2019, up from 56% in 2018 and 55% in 2017.

In 2017, just 39% of organizations hit by ransomware paid to retrieve their encrypted data. That figure rose to 45% in 2018, then shot up to 58% in 2019.

Marriott hit by second data breach exposing “up to” 5.2 million people

Hotel chain Marriott International this week announced that it has been hit by a second data breach exposing the personal details of “up to approximately 5.2 million guests”.

The breach, which began in mid-January 2020 and was discovered at the end of February 2020, saw contact details, including names, addresses, birth dates, gender, email addresses and telephone numbers exposed. Employer name, gender, room stay preferences and loyalty account numbers were also exposed.

The hotel company has stressed that not all data was exposed for each person.

Marriott has also said that at present it does not believe passports, payment details or passwords were exposed in the data breach.

The data is believed to have been accessed by an unknown third party using the login credentials of two employees at a group hotel operated as a franchise. Marriott has said that it has notified relevant authorities, and has begun notifying those whose data was exposed in the breach. It has also set up a dedicated website to help those impacted by the breach.

Lawyers urged to switch off Alexa when working from home

Law firms are warning their employees to turn off their smart speakers while working from home due to security concerns.

Smart speakers such as Amazon’s Echo series and Google’s Nest range have become wildly popular in Britain with an estimated 34pc of households now using them.

But privacy and security experts have repeatedly said the devices may pose a security threat and now law firms have advised staff not to disclose sensitive details when they are in use nearby.

A spokesman from one firm of solicitors said that that hackers could access sensitive details through the speakers, telling their staff to check the default settings on the speaker and to the extent that you can, switch them off during the working day.

The Importance of Maintaining Good Cyber Hygiene During the Coronavirus Crisis

Businesses are making significant changes in response to the virus, including asking employees to work from home for the first time. These new practices have often been implemented as quickly as possible, with a priority on keeping the business operations going.

At the same time, the cyber and information security consultants at Black Arrow are seeing reports from specialist intelligence and the wider media which show cyber criminals are feasting on the current chaos as they target employees and companies who let their guard down.

Half of all UK Firms and Three-Quarters of Large Firms Suffered Security Breach Last Year

Nearly half (46%) of UK firms reported suffering a security breach or cyber-attack over the past year, an increase on previous years, but they are getting better at recovering from and deflecting such blows, according to the government.

The annual Cyber Security Breaches Survey revealed an increase in the overall volume of businesses reporting incidents, up from 32%. The number of medium (68%) and large (75%) businesses reporting breaches or attacks also jumped, from 60% and 61% respectively.

This puts the 2020 report’s findings in line with the first government analysis in 2017, it claimed.

Of those businesses that reported incidents, more are experiencing these at least three times a week than in 2017 (32% versus 22%).

The government also claimed that organisations are experiencing more phishing attacks (from 72% to 86%) whilst fewer are seeing malware (from 33% to 16%) than three years ago.

#COVID19 Drives Phishing Emails Up 667% in Under a Month

Phishing emails have spiked by over 600% since the end of February as cyber-criminals look to capitalize on the fear and uncertainty generated by the COVID-19 pandemic.

A security vendor observed just 137 incidents in January, rising to 1188 in February and 9116 so far in March. Around 2% of the 468,000 global email attacks detected by the firm were classified as COVID-19-themed.

As is usually the case, the attacks used widespread awareness of the subject to trick users into handing over their log-ins and financial information, and/or unwittingly downloading malware to their computers

Of the COVID-19 phishing attacks, 54% were classified as scams, 34% as brand impersonation attacks, 11% blackmail and 1% as business email compromise (BEC).

As well as the usual lures to click through for more information on the pandemic, some scammers are claiming to sell cures and/or face-masks, while others try to elicit investment in companies producing vaccines, or donations to fight the virus and provide support to victims.

This is a new low for cyber-criminals, who are acting like piranha fish, cowardly attacking people on mass when they are at their most vulnerable. It’s vital that the public remain vigilant against scam emails during this challenging time.

Attackers exploiting critical zero-day Windows flaw

Microsoft has discovered a severe vulnerability in all supported versions of Windows, which enables criminals to remotely run malware – including ransomware – on a target machine.

According to the report, the security vulnerability has not been previously disclosed and there is currently no fix.

The “critical” vulnerability revolves around how the operating system handles and renders fonts. All it takes is for the victim to open or preview a malicious document, and the attacker can remotely run different forms of malware.

Microsoft said the vulnerability is being exploited in the wild, and different hacking groups are initiating “limited, targeted attacks”.

Although there is as yet no patch, the company announced a temporary workaround for affected Windows users, which involves disabling the Preview and Details panes in Windows explorers.

WHO Targeted in Espionage Attempt, COVID-19 Cyberattacks Spike

The DarkHotel group could have been looking for information on tests, vaccines or trial cures.

The World Health Organization (WHO) has attracted the notice of cybercriminals as the worldwide COVID-19 pandemic continues to play out, with a doubling of attacks recently, according to officials there. Problematically, evidence has also now apparently surfaced that the DarkHotel APT group has tried to infiltrate its networks to steal information.

A cyber security researcher told Reuters that he personally observed a malicious site being set up on March 13 that mimicked the WHO’s internal email system. Its purpose was to steal passwords from multiple agency staffers, and noted that he realised “quite quickly that this was a live attack on the World Health Organization in the midst of a pandemic.”

The attack appeared to be aimed at achieving a foothold at the agency rather than being an end unto itself. The targeting infrastructure seems to focus on certain types of healthcare and humanitarian organisations that are uncommon for cybercriminals and this could suggest the actor or actors behind the attacks are more interested in gathering intelligence, rather than being financially motivated.

Stolen data of company that refused REvil ransom payment now on sale

Operators of the Sodinokibi (aka Sodin or REvil) Ransomware as a Service (RaaS) recently published over 12GB of data that allegedly belongs to one of its victims – Brooks International – that refused to pay ransom.

RaaS is the malware for lazy crooks who just want to launch attacks at the press of a button: it enables novice cybercriminals to build automated campaigns using third-party kits sold on the dark web. They don’t have to break a sweat by learning about malware, teaching themselves how encryption works, writing ransomware code, running an anonymous webserver on Tor to collect the loot, distributing decryption keys, or otherwise getting their hands dirty with technical details.

Sodinokibi – a GandCrab derivative blamed for numerous attacks that took place last year – is a prime example of RaaS.

Concern over Zoom video conferencing after MoD bans it over security fears

Concerns have been raised over the security of video conferencing service Zoom after the Ministry of Defence banned staff from using it.

Downing Street published pictures of Prime Minister Boris Johnson using the app to continue holding Cabinet meetings with senior MPs – where sensitive information like matters of national security are discussed – while observing rules on social distancing to curb the coronavirus outbreak.

But MoD staff were told this week that use of the software was being suspended with immediate effect while ‘security implications’ were investigated, with users reminded of the need to be ‘cautious about cyber resilience’ in ‘these exceptional times’.

One source commented that ‘it is astounding that thousands of MoD staff have been banned from using Zoom only to find a sensitive Government meeting like that of the Prime Minister’s Cabinet is being conducted over it’.

A message to MoD staff said: ‘We are pausing the use of Zoom, an internet-based video conferencing service, with immediate effect whilst we investigate security implications that come with it.’ The email added that a decision will then be made about whether to continue using the programme.

Adobe issues emergency fix for file-munching bug

Adobe has released another security patch outside of its usual routine this month to deal with a strange bug that can allow attackers to delete victims’ files.

The file-deleting bug stems from a time-of-check to time-of-use race condition vulnerability, which happens when two system operations try to access shared data at the same time. That allows an attacker to manipulate files on the victim’s system. The company warned that successful exploitation could lead to arbitrary file deletion.

To successfully exploit the flaw, an attacker would need to convince a victim to open a malicious file, Adobe has said.

Emerging Chinese APT Group ‘TwoSail Junk’ Mounts Mass iPhone Surveillance Campaign

The malware, the work of a new APT called TwoSail Junk, allows deep surveillance and total control over iOS devices.

A recently discovered, mass-targeted watering-hole campaign has been aiming at Apple iPhone users in Hong Kong – infecting website visitors with a newly developed custom surveillance malware. The bad code – the work of a new APT called “TwoSail Junk” – is delivered via a multistage exploit chain that targets iOS vulnerabilities in versions 12.1 and 12.2 of Apple’s operating system, according to researchers.

Watering-hole campaigns make use of malicious websites that lure visitors in with targeted content – cyberattackers often post links to that content on discussion boards and on social media to cast a wide net. When visitors click through to a malicious website, background code will then infect them with malware.

New attack on home routers sends users to spoofed sites that push malware

A recently discovered hack of home and small-office routers is redirecting users to malicious sites that pose as COVID-19 informational resources in an attempt to install malware that steals passwords and cryptocurrency credentials, researchers said on Wednesday.

The compromises are hitting Linksys routers and D-Link devices.

It remains unclear how attackers are compromising the routers. The researchers suspect that the hackers are guessing passwords used to secure routers’ remote management console when that feature is turned on. It was also hypothesized that compromises may be carried out by guessing credentials for users’ Linksys cloud accounts.

Russia’s FSB wanted its own IoT botnet

If you thought the Mirai botnet was bad, what about a version under the control of Russia’s military that it could point like an electronic cannon at people it didn’t like? That’s the prospect we could face after the reported emergence of secret Russian project documents online last week.

The documents, which come from hacking group Digital Revolution but haven’t been verified, suggest that Russia’s Federal Security Service (in Russian, the FSB), has been working on an internet of things (IoT) botnet of its own called Fronton.

Mirai was a botnet that infected IoT devices by the million, taking advantage of default login credentials to co-opt them for attackers. They then pointed it at DNS service provider Dyn, mounting a DDoS attack that took down large internet services for hours.

Maintaining Good Cyber Hygiene during the Coronavirus Crisis - Guernsey Press 24 March 2020

With more of us working from home in the coronavirus crisis, there is evidence of increasing attacks by cyber criminals who are exploiting those unaware of the risks, according to Tony Cleal, director of Guernsey’s Black Arrow Cyber Consulting BUSINESSES are making significant changes in response to the virus, including asking employees to work from home for the first time. These new practices have often been implemented as quickly as possible, with a priority on keeping the business operations going. At the same time, the cyber and information security consultants at Black Arrow are seeing reports from specialist intelligence and the wider media which show cyber criminals are feasting on the current chaos as they target employees and companies who let their guard down. ‘Cyber criminals usually target people, not technology, to get into their employer’s systems. Companies need to ensure they consider all the basic risks to prevent this, and implement layers of defence that start with the user. As an analogy, the easiest way for a criminal to get into someone’s home is to convince the resident to let them in, for example by pretending to repair an emergency gas leak. It doesn’t matter how good the window locks are, or how sophisticated the burglar alarm is; all they need to do is knock on the front door and be convincing. Thousands of coronavirus scam and malware sites are being created on a daily basis, and we see cyber criminals taking advantage of the crisis to get access to the organisation’s money and information’. That means companies and employees need to maintain good cyber hygiene when working from home, just as they do in the office. People behave differently at home, and are often less alert to information security risks than in the office. ‘We have seen Guernsey employees posting pictures on Facebook to show their new desk at home, but these pictures risk showing confidential documents on the table and screen. This is further evidence that cyber security is a business-wide risk that needs the aligned strength of people and culture, as well as business operations and technology’. Some smaller businesses consider cyber security to be more relevant for larger organisations. ‘Weakened defences will always be exploited, whether by biological viruses or malicious actors. 43% of cyber attacks hit smaller businesses, and a breach now on top of everything else would likely be catastrophic. Luckily, there are things you can do to protect yourself, even with limited resources; we can help ensure that the scarce money is spent wisely by addressing cyber security as a business-wide risk owned by the business leadership.’ Tony concluded: ‘Now more than ever, because of the disruption and changes to business practices, companies need to take appropriate steps to protect themselves against cyber-attacks. We are committed to helping improve cyber hygiene in Guernsey. This started when I used my experience in British Intelligence to lead the review of cyber security across the Bailiwick for the GFSC, which informed the forthcoming new standards. Now at Black Arrow we are reducing our prices during this crisis, to make cyber hygiene easier for all organisations; of course, charities and non-profits can continue to contact us for help free of charge.’ https://guernseypress.com/news/2020/03/24/maintaining-good-cyber-hygiene/

Cyber Weekly Flash Briefing for 20 March 2020 – Working from home brings security challenges, COVID-19 scams and malware, VPNs and MFA, broadband strain, critical patches

Links to articles are for interest and awareness and linking to or reposting external content does not endorse any service or product, likewise we are not responsible for the security of external links.

Working from Home: COVID-19’s Constellation of Security Challenges

Organisations are sending employees and students home to work and learn — but implementing the plan opens the door to more attacks, IT headaches and brand-new security challenges.

As the threat of coronavirus continues to spread, businesses are sending employees home to work remotely, and students are moving to online classes. But with the social distancing comes a new threat – a cyber-related one.

As organisations rush to shift their businesses and classes online, cybercriminals are ramping up their tactics to take advantage of those who may have inadequate or naive security postures as a result. Given the challenges in securing work- and learn-from-home environments, the attack surface represents an attractive opportunity for threat actors

Thousands of COVID-19 scam and malware sites are being created on a daily basis

Malware authors and fraudsters aren't letting a tragedy go to waste.

In the midst of a global coronavirus (COVID-19) pandemic, hackers are not letting a disaster go to waste and have now automated their coronavirus-related scams to industrial levels.

According to multiple reports, cybercriminals are now creating and putting out thousands of coronavirus-related websites on a daily basis.

Most of these sites are being used to host phishing attacks, distribute malware-laced files, or for financial fraud, for tricking users into paying for fake COVID-19 cures, supplements, or vaccines.

EU warns of broadband strain as millions work from home

The EU has called on streaming services such as Netflix and YouTube to limit their services in order to prevent the continent’s broadband networks from crashing as tens of millions of people start working from home.

Until now, telecoms companies have been bullish that internet infrastructure can withstand the drastic change in online behaviour brought about by the coronavirus outbreak.

But on Wednesday evening, Thierry Breton, one of the European commissioners in charge of digital policy, said streaming platforms and telecoms companies had a “joint responsibility to take steps to ensure the smooth functioning of the internet” during the crisis.

COVID-19: With everyone working from home, VPN security has now become paramount

With most employees working from home amid today's COVID-19 (coronavirus) outbreak, enterprise VPN servers have now become paramount to a company's backbone, and their security and availability must be the focus going forward for IT teams.

It is critical that the VPN service is patched and up to date because there will be more scanning against these services.

It is also critical that multi factor authentication (MFA or 2FA) is used to protect connections over VPN.

What do you not want right now? A bunch of Cisco SD-WAN, Webex vulnerabilities? Here are a bunch of them

Cisco has issued a series of security updates for its SD-WAN and Webex software, just when they're most needed.

SD-WAN is host to five vulnerabilities ranging from privilege escalation to remote code injection.

Meanwhile, the Webex video-conferencing software also needs some sorting out right when everyone's working from home amid the coronavirus pandemic.

The patch bundle includes a fix for Cisco Webex Network Recording Player for Microsoft Windows and Cisco Webex Player for Microsoft Windows. A hacker can send a suitably crafted file in either the Advanced Recording Format (ARF) or the Webex Recording Format (WRF), and if the recipient clicks on it on a vulnerable computer, they get pwned. iOS users also need to patch an information-disclosure bug.

The other fixes mention SQL injection and cross-site scripting flaws.

Windows 10 or Mac user? Patch Adobe Reader and Acrobat now to fix 9 critical security flaws

Adobe has released an important security update for its popular PDF products, Adobe Acrobat and Reader after missing its usual release aligned with Microsoft Patch Tuesday.

The company has released an update for the PDF software for Windows and macOS machines. The update addresses nine critical flaws and four vulnerabilities rated as important.

The critical flaws include an out-of-bounds write, a stack-based overflow flaw, a use-after-free, buffer overflow, and memory corruption bug.

All the critical flaws allow for arbitrary code execution, meaning attackers could use them to rig a PDF to install malware on a computer running a vulnerable version of the software.

WordPress and Apache Struts account for 55% of all weaponized vulnerabilities

Comprehensive study looks at the most attacked web technologies of the last decade.

A study that analysed all the vulnerability disclosures between 2010 and 2019 found that around 55% of all the security bugs that have been weaponized and exploited in the wild were for two major application frameworks, namely WordPress and Apache Struts.

The Drupal content management system ranked third, followed by Ruby on Rails and Laravel, according to a report published this week.

In terms of programming languages, vulnerabilities in PHP and Java apps were the most weaponized bugs of the last decade.

Trickbot malware adds new feature to target telecoms, universities and finance companies

Researchers uncover a Trickbot campaign with new abilities that looks like it's being used in an effort to steal intellectual property, financial data - and potentially for espionage.

The new form of the infamous Trickbot malware is using never-before-seen behaviour in attacks targeting telecommunications providers, universities and financial services in a campaign that looks to be going after intellectual property and financial data.

Trickbot has been in operation since 2016 and, while it started life as a banking trojan, the modular nature of the malware means it can be easily re-purposed for other means, which has led to it becoming one of the most advanced and capable forms of malware attack delivery in the world today.

And now it has been updated with yet another new capability, with a module that uses brute force attacks against targets mostly in telecoms, education, and financial services in the US and Hong Kong. These targets are pre-selected based on IP addresses, indicating that the attackers are going after them specifically.

Most organizations have yet to fix CVE-2020-0688 Microsoft Exchange flaw

Organisations are delaying in patching Microsoft Exchange Server flaw (CVE-2020-0688) that Microsoft fixed with February 2020 Patch Day updates.

The CVE-2020-0688 flaw resides in the Exchange Control Panel (ECP) component, the root cause of the problem is that Exchange servers fail to properly create unique keys at install time.

A remote, authenticated attacker could exploit the CVE-2020-0688 vulnerability to execute arbitrary code with SYSTEM privileges on a server and take full control.

Two Trend Micro zero-days exploited in the wild by hackers

Hackers tried to exploit two zero-days in Trend Micro antivirus products, the company said in a security alert this week.

The Japanese antivirus maker has released patches on Monday to address the two zero-days, along with three other similarly critical issues (although, not exploited in the wild).

According to the alert, the two zero-days impact the company's Apex One and OfficeScan XG enterprise security products.

Trend Micro did not release any details about the attacks.

These two zero-days mark the second and third Trend Micro antivirus bugs exploited in the wild in the last year.

Most ransomware attacks take place during the night or over the weekend

27% of all ransomware attacks take place during the weekend, 49% after working hours during weekdays

The vast majority of ransomware attacks targeting the enterprise sector occur outside normal working hours, during the night or over the weekend.

According to a report published this week, 76% of all ransomware infections in the enterprise sector occur outside working hours, with 49% taking place during night-time over the weekdays, and 27% taking place over the weekend.

The numbers were compiled from dozens of ransomware incident response investigations from 2017 to 2019.

The reason why attackers are choosing to trigger the ransomware encryption process during the night or weekend is because most companies don't have IT staff working those shifts, and if they do, they are most likely short-handed.

If a ransomware attack does trigger a security alert within the company, then there would be nobody to react right away and shut down a network, or the short-handed staff would have a hard time figuring what's actually happening before the ransomware encryption process ends and the company's network is down & ransomed.

Protection for smaller businesses - cyber security is more critical than ever before

Some small and medium-sized businesses (SMBs) consider cyber security either a luxury or an issue to be dealt with once their budget is a bit larger.

Unfortunately, it is these businesses that are most likely to be targeted for cybercrime.

In fact, 43 percent of cyberattacks target small businesses. Criminals know larger corporations have strong security systems, but smaller businesses frequently leave themselves vulnerable.

If you run an SMB and cyber security is not yet a priority, it's time to change that.

Luckily, there are things you can do to protect yourself, even when resources are limited, and we can help you ensure you spend your money wisely and get the best value from your spend to protect you where it matters.

There are a lot of other things to worry about right now, for businesses of all sizes, but cyber security is more critical now than it ever have been.

A breach now on top of everything else that is going on would likely be catastrophic to any business.

How dependent is your business on technology? Have you ever stopped to think how long your business could operate without it? This week Tony asks firms to think about how long they could operate

Welcome to this week's Black Arrow Cyber Tip Tuesday, this week I'm talking about firms thinking about how dependent they are on technology to operate. Have you ever stopped to think how dependent your business is on IT and thought about how long you would be able to continue if you lost access to your data or systems for any period of time? Thinking about email alone, how long could your business operate without being able to access email? All firms are technology firms now to one extent or the other and many do not appreciate just how dependent their operations are on IT. A loss of your IT systems could be catastrophic to a business and making sure you have plans in place so you know what to do and how you will be able to recover are critically important. Talk to us to see how we can help with planning and preparedness to help ensure your business can survive.

Cyber Weekly Flash Briefing for 13 March 2020 – more Coronavirus based phishing, adapting ways of working, emergency Microsoft patch, businesses breached due to employee error, IoT traffic unencrypted

Cyber Weekly Flash Briefing for 13 March 2020 – more Coronavirus based phishing, adapting ways of working, emergency Microsoft patch, businesses breached due to employee error, IoT traffic unencrypted

More coronavirus phishing campaigns detected

Caution required when accessing coronavirus-related emails.

Cybercriminals often use major global events to spread malware and steal data, and the recent coronavirus outbreak is no different.

Security experts have identified two phishing campaigns that take advantage of coronavirus concerns to infect devices with the Agent Tesla keylogger.

According to the report, cybercriminals are distributing emails that appear to originate from The Centre for Disease Control (CDC) or the World Health Organisation (WHO). The emails claim the virus is now airborne and that new cases have been confirmed in the victim’s vicinity.

Attached to the messages is a file named "SAFETY PRECAUTIONS", which looks like an Excel document, but is in fact an executable file (.exe) capable of sowing the trojan.

How coronavirus COVID-19 is accelerating the future of work

The coronavirus is forcing enterprises to rethink the way they do business and dust off policies for security, business continuity, and remote workers. Chances are that some of these efforts will stick

The coronavirus outbreak may speed up the evolution of work and ultimately retool multiple industries as everything from conferences to collaboration to sales and commercial real estate are rethought.

Millions of UK businesses experience data breaches due to employee error

Employees often click on fraudulent links and can't spot a phishing email.

Employee error is the cause of 60 percent of all data breaches among UK businesses according to a new report from insurance broker Gallagher.

Polling 1,000 UK business leaders, Gallagher found the most common cause (39 percent) of employee-related breaches was malware downloaded accidentally via fraudulent links.

Phishing is also a major risk factor, responsible for 35 percent of infections. While employees pushing sensitive data outside company systems accounted for a further 28 percent.

The report also claims that almost a third of affected businesses (30 percent) have had their operations knocked out for four to five days as a result of employee error.

Respondents also reported reputational damage (14 percent) and financial consequences (12 percent), which included fines issued by data privacy regulators.

Most executives (71 percent) are aware of the problem and almost two thirds (64 percent) said they regularly remind employees about the risk of cyber crime.

Virtually all businesses are at risk of a cyber attack and as this research shows, it is often an employee mistake which causes the problem.

AMD processors going back to 2011 suffer from worrying security holes

Pair of freshly revealed attacks have not yet been patched

AMD’s processors from as early as 2011 through to 2019 are carrying vulnerabilities that are as yet unpatched, according to some freshly published research.

Known as ‘Take A Way’ (every security problem needs a snappy name, of course), security researchers said that they reverse-engineered the L1D cache way predictor in AMD silicon in order to discover two new potential attack vectors.

Given all the attention which has been focused on the flaws in Intel’s CPUs in recent times – vulnerabilities which haven’t affected AMD chips in a number of cases – this might just serve as a reminder that no one’s silicon is bulletproof.

F-Secure reports a steep rise in hacking attempts

The latest Attack landscape H2 2019 report from F-Secure has found that there has been a jump in the volume of cyber attacks targeting internet users

In the report, F-Secure said that in the first half of 2019, the company’s global network of honeypots experienced a jump in cyber attack traffic.

The volume of such attacks rose from 246 million in H1 2017 to 2.9 billion in H1 2019. In the second half of the year, according to F-Secure, the pace of attack traffic continued but at a slightly reduced rate. F-Secure said there were 2.8 billion hits to its honeypot servers in H2 2019. Distributed Denial of Service (DDos) attacks drove this deluge, accounting for two-thirds of the traffic.

Its research found that the US is the country whose IP space played host to the greatest number of attacks, followed by China and Russia.

This ransomware campaign has just returned with a new trick

Paradise ransomware is back again - and the criminals behind it appear to be testing out new tactics ahead of what could be a more prolific campaign.

A ransomware campaign has returned with a new trick to fool the unwary into compromising their network with file-encrypting malware. And it's an attack that many Windows machines won't even recognise as potentially malicious.

The new variant of Paradise ransomware, which has been active in one form or another since 2017, spreads via phishing emails, but it's different from other ransomware campaigns because it uses an uncommon – but effective – file type to infiltrate the network.

This campaign leverages Internet Query files (IQY), which are text files read by Microsoft Excel to download data from the internet. IQY is a legitimate file type, so many organisations won't block it.

Ransomware Threatens to Reveal Company's 'Dirty' Secrets

Sticking with ransomware, the operators of the Sodinokibi Ransomware are threatening to publicly share a company's "dirty" financial secrets because they refused to pay the demanded ransom.

As organizations decide to restore their data manually or via backups instead of paying ransoms, ransomware operators are escalating their attacks.

In a new post by the Sodinokibi operators to their data leak site, we can see that attackers are not only publishing victim's data but also sifting through it to find damaging information that can be used against the victim.

In the above post, the attackers are threatening to sell the Social Security Numbers and date of births for people in the data to other hackers on the dark web.

They also intimate that they found "dirty" financial secrets in the data and threaten to disclose it.

Microsoft Releases Emergency Patch for Wormable Bug That Threatens Corporate LANs

Microsoft released an emergency out-of-band patch to fix a SMBv3 wormable bug on Thursday that leaked earlier this week. The patch for the vulnerability is now rolling out to Windows 10 and Windows Server 2019 systems worldwide, according to Microsoft.

On Wednesday Microsoft warned of a wormable, unpatched remote code-execution vulnerability in the Microsoft Server Message Block protocol – the same protocol that was targeted by the infamous WannaCry ransomware in 2017.

The critical bug affects Windows 10 and Windows Server 2019, and was not included in Microsoft’s Patch Tuesday release this week.

Nearly all IoT traffic is unencrypted

IoT devices are considered "low-hanging fruit" among cybercriminals.

Practically all of the traffic flowing from Internet of Things (IoT) devices is not encrypted, consequently putting both businesses and their customers at unnecessary risk of data theft and all others that follow.

This is according to a new report which analysed 1.2 million IoT devices in thousands of physical locations across enterprise IT and healthcare organisations, finding that 98 per cent of all IoT device traffic is unencrypted.

That basically means that if intercepted, the data could be easily read and used.

So the question arises – how easy is it to eavesdrop on the data exchange between IoT devices and their respective servers? The report claims 57 per cent of IoT devices are vulnerable to either medium or high-severity attacks. IoT is perceived as “low-hanging fruit” for cybercriminals.

Microsoft takes down global zombie bot network

Microsoft has said it was part of a team that dismantled an international network of zombie bots.

The network call Necurs infected over nine million computers and one of the world's largest botnets.

Necurs was responsible for multiple criminal scams including stealing personal information and sending fake pharmaceutical emails.

Cyber-criminals use botnets to remotely take over internet-connected devices and install malicious software.

The software can be used to send spam, collect information about what activity the computer is used for or delete information without notifying the owner.

Tom Burt, Microsoft's vice-president for customer security and trust, said in a blog post that the takedown of Necurs was the result of eight years of planning and co-ordination with partners in 35 countries.

Watch out for Office 365 and G Suite scams, FBI warns businesses

The menace of Business Email Compromise (BEC) is often overshadowed by ransomware but it’s something small and medium-sized businesses shouldn’t lose sight of.

Bang on cue, the FBI Internet Crime Complaint Center (IC3) has alerted US businesses to ongoing attacks targeting organisations using Microsoft Office 365 and Google G Suite.

Warnings about BEC are ten-a-penny but this one refers specifically to those carried out against the two largest hosted email services, and the FBI believes that SMEs, with their limited IT resources, are most at risk of these types of scams:

Between January 2014 and October 2019, the Internet Crime Complaint Center (IC3) received complaints totaling over $2.1 billion in actual losses from BEC scams targeting Microsoft Office 365 and Google G Suite.

As organisations move to hosted email, criminals migrate to follow them.

As with all types of BEC, after breaking into the account, criminals look for evidence of financial transactions, later impersonating employees to redirect payments to themselves.

For good measure, they’ll often also launch phishing attacks on contacts to grab even more credentials, and so the crime feeds itself a steady supply of new victims.

The deeper question is why BEC scams continue to be such a problem when it’s well understood that they can be defended against using technologies such as multi-factor authentication (MFA).

Microsoft Exchange Server Flaw Exploited by multiple nation state (APT) groups

A vulnerability in Microsoft Exchange servers is being actively exploited by multiple APT groups, researchers warn.

Multiple threat groups are actively exploiting a vulnerability in Microsoft Exchange servers, researchers warn. If left unpatched, the flaw allows authenticated attackers to execute code remotely with system privileges.

The vulnerability in question (CVE-2020-0688) exists in the control panel of Exchange, Microsoft’s mail server and calendaring server, and was fixed as part of Microsoft’s February Patch Tuesday updates. However, researchers in a Friday advisory said that unpatched servers are being exploited in the wild by unnamed advanced persistent threat (APT) actors.

Cyberattackers are delivering malware by using links from whitelisted sites

Legitimate-looking links from OneDrive, Google Drive, iCloud, and Dropbox slip by standard security measures.

Bad actors have added a new snare to their bag of social engineering tricks— malicious OneDrive, Google Drive, iCloud, and Dropbox links. A new whitepaper asking "Is SaaS the New Trojan Horse in the Age of the Cloud?" describes this latest attack vector.

Links to these legitimate sites can often slip by standard security measures that stop malware and block access to suspicious sites. Many of these services are whitelisted by security products because they are approved services, meaning that an enterprise has few or no defences against these advanced attacks. These services are the latest tactic designed to dupe users into divulging their credentials or unknowingly download and install malware.

Tech Firms Offer Free Remote Working Tools, as Coronavirus Cases Surge

Move comes as companies scramble to polish remote working processes

Six technology companies are rolling out free or upgraded enterprise collaboration tools under a new “Open for Business” hub, in a bid to capture new users – and support enterprises scrambling to implement remote working protocols as coronavirus cases surge.

In the US, Amazon, Microsoft and Facebook have advised Seattle-area employees to work from home for the next few weeks. In the UK most companies are holding fire for now, but are most are rapidly updating policies and assessing tools.

Large organisations might be able to work through some of the emerging provisioning issues that come with a surge of remote workers — i.e. by increasing the number of licenses for their firewalls and VPNs — many small businesses don’t have the ability to quickly provision the resources they need to support their employees when working remotely.

This includes things like a clear desk policy to ensure confidential papers are not left on your desk overnight, or ensuring employees don't read confidential documents on a train with other passengers, or worse still throwing away documents in a public bin when instead they should be shredded.

Cyber Security is the subsection of Information Security that refers to being connected to the Internet and online systems.

It includes storing documents on your computer or cloud server, or sending documents by email, or accessing online payments systems.

All these require strong controls to prevent unauthorised access.

Your objective is to protect the confidentiality, integrity and the availability of the information.
