Black Arrow Cyber Threat Briefing 30 July 2021: Many Workers Ignore Security Risks To Maximize Productivity; Financial Services Accounting For Nearly 40% Of All Phishing URLs; Half Of Organisations Are Ineffective At Countering Phishing And Ransomware Threats; 36% Of Organisations Suffered A Serious Cloud Security Data Leak Or A Breach In The Past Year; HP Finds 75% Of Threats Were Delivered By Email In First Six Months Of 2021
Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.
Top Cyber Stories of the Last Week
Many Workers Ignore Security Risks To Maximize Productivity
A large proportion of employees often take shortcuts to optimize productivity at work, despite understanding the security risks, new data suggests. According to a survey which polled 8,000 workers worldwide, almost four in five (79%) have engaged in one or more “risky activity” in the past twelve months. In a third of cases (35%), this involved saving passwords to their browser. A similar percentage admitted to using a single password across multiple online accounts, while 23% connected personal devices to corporate networks.

Financial Services Accounting For Nearly 40% Of All Phishing URLs
A report was released for H1 2021, which revealed that there has been a major jump in phishing attacks since the start of the year with a 281 percent spike in May and another 284 percent increase in June, for a total of 4.2 billion phishing emails detected for June alone. For this 6-month window researchers identified Crédit Agricole as the most impersonated brand, with 17,555 unique phishing URLs, followed by Facebook, with 17,338, and Microsoft, with 12,777.

Half Of Organisations Are Ineffective At Countering Phishing And Ransomware Threats
Half of organisations are not effective at countering phishing and ransomware threats. The findings come from a study compiled from interviews with 130 cyber security professionals in mid-sized and large organisations. “Phishing and ransomware were already critical enterprise security risks even before the pandemic hit and, as this report shows, the advent of mass remote working has increased the pressure of these threats,”. “Organisations need multi-layered defences in place to mitigate these risks.”

36% Of Organisations Suffered A Serious Cloud Security Data Leak Or A Breach In The Past Year
As cloud adoption accelerates and the scale of cloud environments grows, engineering and security teams say that risks—and the costs of addressing them—are increasing. The findings are part of the State of Cloud Security 2021 survey. The survey of 300 cloud pros (including cloud engineers; security engineers; DevOps; architects) found that 36% of organisations suffered a serious cloud security data leak or a breach in the past 12 months, and eight out of ten are worried that they’re vulnerable to a major data breach related to cloud misconfiguration. 64% say the problem will get worse or remain unchanged over the next year.

HP Finds 75% Of Threats Were Delivered By Email In First Six Months Of 2021
According to the latest HP Report, email is still the most popular way for malware and other threats to be delivered, with more than 75% of threats being sent through email messages. The report -- covering the first half of 2021 -- is compiled based on customers who opt to share their threat alerts with the company. HP's researchers found that there has been a 65% rise in the use of hacking tools downloaded from underground forums and filesharing websites from H2 2020 to H1 2021. Some of the tools can solve CAPTCHA challenges using computer vision techniques.
Data Breach Costs Hit Record High Due To Pandemic
Data breaches have always proved costly for victimized organisations. But the coronavirus pandemic made a bad situation even worse. A report released Wednesday looks at how and why the average cost of dealing with a data breach has jumped to a new high. The average cost of a data breach among companies surveyed reached $4.24 million per incident, the highest in 17 years.

Top 30 Critical Security Vulnerabilities Most Exploited By Hackers
Intelligence agencies in Australia, the U.K., and the U.S. issued a joint advisory on Wednesday detailing the most exploited vulnerabilities in 2020 and 2021, once again demonstrating how threat actors can swiftly weaponize publicly disclosed flaws to their advantage. The top 30 vulnerabilities span a wide range of software, including remote work, virtual private networks (VPNs), and cloud-based technologies, that cover a broad spectrum of products from Microsoft, VMware, Pulse Secure, Fortinet, Accellion, Citrix, F5 Big IP, Atlassian, and Drupal.
https://thehackernews.com/2021/07/top-30-critical-security.html
Average Time To Fix High Severity Vulnerabilities Grows From 197 Days To 246 Days In 6 Months: Report
A recent report has found that the remediation rate for severe vulnerabilities is on the decline, while the average time to fix is on the rise. The report, which is compiled monthly, covers window of exposure, vulnerability by class and time to fix. The latest report found that the window of exposure for applications has increased over the last six months while the top-5 vulnerability classes by prevalence remain constant, which the researchers behind the report said was a "systematic failure to address these well-known vulnerabilities." According to researchers, the time to fix vulnerabilities has dropped 3 days, from 205 days to 202 days. The average time to fix is 202 days, the report found, representing an increase from 197 days at the beginning of the year. The average time to fix for high vulnerabilities grew from 194 days at the beginning of the year to 246 days at the end of June.
Why Remote Working Leaves Us Vulnerable To Cyber Attacks
An industry survey found 56% of senior IT technicians believe their employees have picked up bad cyber security habits while working from home. For Example. A cyber-crime group known as REvil took meticulous care when picking the timing for its most recent attack - US Independence Day, 4 July. They knew many IT specialists and cyber-security experts would be on leave, enjoying a long weekend off work. Before long, more than 1,000 companies in the US, and at least 17 other countries, were under attack from hackers. Many firms were forced into a costly downtime period as a result. Among those targeted during the incident was a well-known software provider, Kaseya. REvil used Kaseya as a conduit to spread its ransomware - a malware that can scramble and steal an organisation's computer data - through other corporate and cloud-based networks that use the software.

Stop Mitigating Cyber Security Threats And Start Preventing Them
The impacts of a successful cyber attack can be devastating. Through multiple forms of extortion, criminals can use stolen data and other business-critical assets, including sensitive financial and customer data to hold companies hostage with just one campaign. The average cost of a phishing attack last year was $832,500, with zero-day attacks costing around $1,238,000. Spending this amount of money to recover from a cyber attack could bring a company to its knees. Today’s cyber attacks present very real existential threats to businesses and C-level executives are beginning to fully realize the gravity of these threats. It is critical that organizations invest in solutions that are going to help stop these attackers before they enter their environments.

Black Arrow Cyber Threat Briefing 05 March 2021: New Strain Of Ransomware Implements Self-Spreading Capabilities; One In Four People Use Work Passwords For Consumer Websites; Massive Rise In Threats Across Expanding Attack Surfaces; Half of Orgs Concerned Remote Working Puts Them at Greater Risk of Cyber Attacks; Microsoft Patches Four Zero-Day Exchange Server Bugs; A Booming Trade In Bugs Is Undermining Cyber Security; Weaponized Spectre Exploit Discovered; Solarwinds Security Fiasco May Have Started With Simple Password Blunders
Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.
Top Cyber Stories of the Last Week
New Strain Of Ransomware Implements Self-Spreading Capabilities
French experts spotted a new Ryuk ransomware variant that implements self-spreading capabilities to infect other devices on victims’ local networks.
This new version has a new attribute that allows it to self replicate over the local network allowing the malware to propagate itself – machine to machine – within the Windows domain. Once launched, it will spread itself to every Windows machine it can reach.
https://securityaffairs.co/wordpress/115064/reports/ryuk-ransomware-self-spreading-capabilities.html
One In Four People Use Work Passwords For Consumer Websites
The report found that one in four consumers admit to using their work email or passwords to log in to consumer websites and applications such as food delivery apps, online shopping sites and even dating apps. The report found that consumers are neglecting to implement fundamental security safeguards across smart IoT devices at home, which could have serious security ramifications on both the individual and the enterprise amid increased and ongoing remote work spurred by the COVID-19 pandemic.
https://www.helpnetsecurity.com/2021/02/26/use-work-passwords-for-consumer-websites/
Massive Rise In Threats Across Expanding Attack Surfaces
New malware samples nearly doubled: New ransomware samples increased 106% year-over-year. Trojans increased 128%, with threat actors using trojans to exploit lower-severity vulnerabilities. Sophisticated, multi-staged attacks and malware-as-a-service have become the norm. Vulnerabilities hit a new high: 18,341 new vulnerabilities in 2020 have been reported. To stay ahead of attacks, security and risk leaders need sophisticated insights into which vulnerabilities are high-risk and remediation options for all assets, including non-patching options.
https://www.helpnetsecurity.com/2021/02/26/expanding-attack-surfaces/
Half of Organisations Concerned Remote Working Puts Them at Greater Risk of Cyber Attacks
Half of organizations are concerned that the shift to remote work is putting them a greater risk of Cyber Attacks, according to a new study with IDG. A survey of UK CIOs, CTOs and IT decision makers revealed that insecure practices are regularly taking place among remote workers, providing more opportunities for Cyber Criminals to strike.
https://www.infosecurity-magazine.com/news/half-orgs-remote-working-risk/
Microsoft Patches Four Zero-Day Exchange Server Bugs
Microsoft has been forced to release out-of-band patches to fix multiple zero-day vulnerabilities being exploited by Chinese state-backed threat actors. The unusual step was taken to protect customers running on-premises versions of Microsoft Exchange Server.
https://www.infosecurity-magazine.com/news/microsoft-patch-four-zeroday/
A Booming Trade In Bugs Is Undermining Cyber Security
If you discover that a favourite vending-machine dispenses free chocolate when its buttons are pressed just so, what should you do? The virtuous option is to tell the manufacturer, so it can fix it. The temptation is to gorge.
Is Your Browser Extension A Botnet Backdoor?
A company that rents out access to more than 10 million Web browsers so that clients can hide their true Internet addresses has built its network by paying browser extension makers to quietly include its code in their creations. This story examines the lopsided economics of extension development, and why installing an extension can be such a risky proposition.
https://krebsonsecurity.com/2021/03/is-your-browser-extension-a-botnet-backdoor/
Cyber Attack Shuts Down Online Learning At 15 UK Schools
A threat actor was able to access the trust's central network infrastructure and while an investigation took place, all existing phone, email, and website communication had to be pulled. Students are still learning remotely in England. Schools are set to reopen on March 8, but in the meantime, only a small subset of children are attending school physically, such as the children of key workers.
https://www.zdnet.com/article/cyberattack-shuts-down-online-learning-at-15-uk-schools/
First Fully Weaponized Spectre Exploit Discovered Online
A fully weaponized exploit for the Spectre CPU vulnerability was uploaded on the malware-scanning website VirusTotal last month, marking the first time a working exploit capable of doing actual damage has entered the public domain. The exploit was discovered and targets Spectre, a major vulnerability that was disclosed in January 2018. According to its website, the Spectre bug is a hardware design flaw in the architectures of Intel, AMD, and ARM processors that allows code running inside bad apps to break the isolation between different applications at the CPU level and then steal sensitive data from other apps running on the same system.

Solarwinds Security Fiasco May Have Started With Simple Password Blunders
We still do not know just how bad the SolarWinds security breach is. We do know over a hundred US government agencies and companies were cracked. "The largest and most sophisticated attack the world has ever seen," with more than a thousand hackers behind it. It may have all started when an intern first set an important password to "'solarwinds123." Then, adding insult to injury, the intern shared the password on GitHub.

Black Arrow Cyber Threat Briefing 22 January 2021
Black Arrow Cyber Threat Briefing 22 January 2021: Ransomware Biggest Cyber Concern; Ransomware Payments Grew 311% In 2020; Cyber Security Spending To Soar In 2021; Ransomware Provides The Perfect Cover For Other Attacks; Gdpr Fines Skyrocket As Eu Gets Tough On Data Breaches; Popular Pdf Reader Has Database Of 77 Miliion Users Leaked Online; Malware Incidents On Remote Devices Increase
Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities and cyber related news from the last week.
Top Cyber Headlines of the Week
Ransomware is now the biggest Cyber Security concern for CISOs
Ransomware is the biggest cyber security concern facing businesses, according to those responsible for keeping organisations safe from hacking and cyberattacks. A survey of chief information security officers (CISOs) and chief security officers (CISOs found that ransomware is now viewed as the main cyber security threat to their organisation over the course of the next year. Almost half – 46% – of CISOs and CISOs surveyed said that ransomware or other forms of extortion by outsiders represents the biggest cyber security threat.
https://www.zdnet.com/article/ransomware-is-now-the-biggest-cybersecurity-concern-for-cisos/
Crypto ransomware payments grew 311% in 2020
Crypto payments associated with ransomware grew at least 311% in 2020. “Ransomware” refers to a category of malicious computer programs that force users into paying ransoms. Just 0.34% of all cryptocurrency transactions last year were criminal, down from 2.1% in 2019. But that number is bound to go up, said the firm.
https://decrypt.co/54648/crypto-crime-ransomware-chainalysis-report-2020
The SolarWinds hackers used tactics other groups will copy
One of the most chilling aspects of Russia's recent hacking spree—which breached numerous United States government agencies among other targets—was the successful use of a “supply chain attack” to gain tens of thousands of potential targets from a single compromise at the IT services firm SolarWinds. But this was not the only striking feature of the assault. After that initial foothold, the attackers bored deeper into their victims' networks with simple and elegant strategies. Now researchers are bracing for a surge in those techniques from other attackers.
https://www.wired.com/story/solarwinds-hacker-methods-copycats/
Global Cyber Security spending to soar in 2021
The worldwide cyber security market is set to grow by up to 10% this year to top $60bn, as the global economy slowly recovers from the pandemic. Double-digit growth from $54.7bn in 2020 would be its best-case scenario. However, even in the worst case, cyber security spending would reach 6.6%. That would factor in a deeper-than-anticipated economic impact from lockdowns, although the security market has proven to be remarkably resilient thus far to the pandemic-induced global economic crisis. That said, SMB spending was hit hard last year, along with certain sectors like hospitality, retail and transport.
https://www.infosecurity-magazine.com/news/global-cybersecurity-spending-to/
Cyber criminals publish more than 4,000 stolen Sepa files
Sepa rejected a ransom demand for the attack, which has been claimed by the international Conti ransomware group. Contracts, strategy documents and databases are among the 4,000 files released. The data has been put on the dark web - a part of the internet associated with criminality and only accessible through specialised software.
https://www.bbc.co.uk/news/uk-scotland-55757884
Ransomware provides the perfect cover for other attacks
Look at any list of security challenges that CISOs are most concerned about and you’ll consistently find ransomware on them. It’s no wonder: ransomware attacks cripple organizations due to the costs of downtime, recovery, regulatory penalties, and lost revenue. Unfortunately, cybercriminals have added an extra sting to these attacks: they are using ransomware as a smokescreen to divert security teams from other clandestine activities behind the scenes
https://www.helpnetsecurity.com/2021/01/21/ransomware-cover/
Popular PDF reader has database of 77 million users hacked and leaked online
A threat actor has leaked a 14 GB database online containing over 77 million records relating to thousands of users of the Nitro PDF reader software, with users' email addresses, full names, hashed passwords, company names, IP addresses, and other system-related information.
Ransomware victims that have backups are paying ransoms to stop hackers leaking their stolen data
Some organisations that fall victim to ransomware attacks are paying ransoms to cyber-criminal gangs despite being able to restore their own networks from backups, in order to prevent hackers publishing stolen data. Over the course of the past year, many of the most successful ransomware gangs have added an additional technique in an effort to coerce victims into paying ransoms after compromising their networks – publishing stolen data if a payment isn't received.
GDPR fines skyrocket as EU gets tough on data breaches
Europe’s new privacy protection regime has led to a surge in fines for bad actors, according to research published today. Law firm DLA Piper says that, since January 28th, 2020, the EU has issued around €158.5 million (around $192 million) in financial penalties. That’s a 39-percent increase on the previous 20-month period Piper examined in its report, published this time last year. And as well as the increased fines, the number of breach notifications has shot up by 19 percent across the same 12-month period.
https://www.engadget.com/gdpr-fines-dla-piper-report-144510440.html
Malware incidents on remote devices increase
Devices compromised by malware in 2020, 37% continued accessing corporate emails after being compromised and 11% continued accessing cloud storage, highlighting a need for organizations to better determine how to configure business tools to ensure fast and safe connectivity for all users in 2021.

Black Arrow Cyber Threat Briefing - 30 October 2020
Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities and cyber related news from the last week.
Threats
Ransomware
Furniture Giant Steelcase Hit by Suspected Ransomware Attack
Steelcase, the world’s largest maker of office furniture, revealed in a filing with the US Securities and Exchange Commission (SEC) that it had become the latest big name to be hit by a major ransomware attack.
The firm claimed to have detected a cyber-attack on its IT systems last Thursday, October 22.
“The company promptly implemented a series of containment measures to address this situation including temporarily shutting down the affected systems and related operations,” it continued. “The company is actively engaged in restoring the affected systems and returning to normal levels of operations.”
https://www.infosecurity-magazine.com/news/furniture-giant-steelcase/
Multinational energy company Enel Group hit by ransomware again, Netwalker demands $14 million
Multinational energy company Enel Group has been hit by a ransomware attack for the second time this year. This time by Netwalker, who is asking a $14 million ransom for the decryption key and to not release several terabytes of stolen data.
Enel is one of the largest players in the European energy sector, with more than 61 million customers in 40 countries. As of August 10, it ranks 87 in Fortune Global 500, with a revenue of almost $90 billion in 2019.
Ransomware vs WFH: How remote working is making cyber attacks easier to pull off
The unique conditions of 2020 mean businesses are more reliant on being digitally connected than ever before. Cyber criminals know this, which is why ransomware attacks have become even more pervasive – and effective during the course this year.Hackers are breaking into networks of organisations ranging from tech companies to local governments and almost every other sector; encrypting servers, services and files with ransomware before demanding a bitcoin ransom that can be measured in hundreds of thousands or even millions of dollars.
REvil ransomware gang claims over $100 million profit in a year
REvil ransomware developers say that they made more than $100 million in one year by extorting large businesses across the world from various sectors.
They are driven by profit and want to make $2 billion from their ransomware service, adopting the most lucrative trends in their pursuit of wealth.
Phishing
Remote Workers Ignore Training to Open Suspicious Emails
Remote workers are increasingly putting corporate data and systems at risk by failing to follow best practice security, according to new research from Mimecast.
The email security vendor polled over 1000 global respondents working from corporate machines to compile its latest report, Company-issued computers: What are employees really doing with them?
It found a litany of risky behaviour: for example, 73% of respondents frequently use their company-issued device for personal matters such as checking webmail (47%), carrying out financial transactions (38%) and online shopping (35%).
https://www.infosecurity-magazine.com/news/remote-workers-ignore-training/
Malware
Emotet campaign used parked domains to deliver malware payloads
Researchers tracking malicious use of parked domains have spotted the Emotet botnet using such domains to deliver malware payloads as part of a large scale phishing campaign.
Domain owners park their domains using parking service providers to monetize them via advertisement networks while they're not being used to host an active website or online service.
The world of malware has a new rising star - and that's a big problem
A fast-spreading malware-as-a-service offering could be providing an alternative to other well-known malware loaders like Emotet and BazarLoader, experts have warned.
Buer was first discovered in August 2019, when it was used to compromise Windows PCs, acting as a gateway for further attacks to follow.
Buer comes with bot functionality, specific to each download. The bots can be configured depending on a variety of filters, including whether the infected machine is 32 or 64 bits, the country where the exploit is taking place and what specific tasks are required.
https://www.techradar.com/uk/news/the-world-of-malware-has-a-new-rising-star-and-thats-a-problem
Akamai sees doubling in malicious internet traffic as remote world’s bad actors' boom, too
Akamai Technologies’ CEO Tom Leighton is impressed by the amazing traffic levels on the internet during the coronavirus pandemic, and the world technology infrastructure’s ability to handle it. But during the stay-at-home boom, the web and cyber security expert also has been closely watching a boom in bad actors.
With so many people working from home, hackers are taking advantage, and massively increasing the number of attacks as daily routine changes caused by the pandemic are prolonged and become potentially permanent.

News of the security incident emerged over the weekend of October 23 when multiple users took to Twitter to voice their confusion over an email they had received from Amazon.
In an email notification the tech giant explained that it had fired an employee after they unlawfully disclosed some customers’ email addresses to a third party.
'Act of War' Clause Could Nix Cyber Insurance Payouts
Companies relying on their business interruption or property insurance policies to cover ransomware attacks and other cyber damages are running the risk of not having coverage during a major attack if insurers are successful in shielding themselves using the ubiquitous "act of war" clause, according to cyber security and insurance experts.
Therapy patients blackmailed for cash after clinic data breach

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.

Coronavirus Scams: Prepare for Phishing Emails, Fake Alerts and Cyberthreats
As new global stories emerge by the hour on the coronavirus, bad actors are (again) trying to confuse online updates with phishing scams and destructive malware. Here’s why action is required now.
Wherever you turn for news coverage online, coronavirus alarm bells are ringing louder.
But users should not trust all of those bells, as fake news, phishing scams and even malicious malware is actively being distributed under the coronavirus umbrella.
Sadly, a perfect storm may be brewing. As government officials and health experts appeal louder for calm, the public is actually getting more worried and searching the Internet for answers.

Metamorfo Returns with Keylogger Trick to Target Financial Firms
The malware uses a tactic to force victims to retype passwords into their systems – which it tracks via a keylogger.
Researchers have discovered a recent spate of phishing emails spreading a new variant of Metamorfo, a financial malware known for targeting Brazilian companies. Now, however, it’s expanding its geographic range and adding a new technique.
Metamorfo was first discovered in April 2018, in various campaigns that share key commonalities (like the use of “spray and pray” spam tactics). These campaigns however have small, “morphing” differences — which is the meaning behind its name.
This newest variant, which targets payment-card data and credentials at financial institutions with Windows platforms, packs a new trick up its sleeve. Once executed, the malware kills the auto-suggest data entry fields in browsers, forcing victims to write out their passwords – which it then tracks via a keylogger.

What's in your network? Shadow IT and shadow IoT challenge technology sensibilities
A couple of years ago, a survey found most CIOs thought they had roughly 30 to 40 apps running within their enterprises, but researchers at Symantec estimated that the average enterprise actually had at least 1,516 applications -- a number that has doubled over a three-year period.
It's not that CIOs are naive. It's just that shadow IT is a difficult thing to measure, since employees pull down apps outside the official channels, and off budget sheets. To some degree, it's even purposely overlooked, condoned, or even encouraged, as employees need the right tools to do their jobs, and IT can't always be there.
Now, it appears CIOs are battling shadow IT on two fronts. There's the user-initiated apps and clouds, and there's something more insidious -- "shadow IoT."

Remote workers prime targets for cyber attacks
According to a study into the future of work, more than half of CIOs expect a rise in employees working remotely, while 97% say that soon their workforce will be widely dispersed across geographies and time zones. Businesses are being forced to adapt to the rising demand for a dynamic working environment, which can manifest as anything from workers bringing their own devices to work to employees using corporate machines at home as part of a flexible work schedule. However, this increases the security burden through the need for better identity management.

Critical Cisco vulnerabilities put millions of network devices at risk
Five different critical vulnerabilities, collectively known as CPDwn, have been discovered in Cisco’s Discovery Protocol, potentially putting tens of millions of enterprise network devices such as desk phones, cameras, and network switches, at risk.
Cisco Discovery Protocol (CDP) is a level 2 protocol that is used to discover information about Cisco equipment that are directly connected nearby.
According to researchers, this flaw could allow hackers to control the products deep within the network without any human intervention. This could be done remotely by just sending a malicious CDP packet to the target device.
This latest phishing scam is spreading fake invoices loaded with malware - campaigns are launched against financial institutions in the US and UK.
A notorious malware campaign is targeting banks and financial institutions in the US and the UK with cyberattacks that are not only destructive in their own right, but could also be used as the basis for future intrusions by other hackers.
Emotet started life as a banking trojan, but has also evolved into a botnet, with its criminal operators leasing out its capabilities to those who want to distribute their own malware to compromise machines.
Such is the power of Emotet that at one point last year it accounted for almost two-thirds of malicious payloads delivered in phishing attacks.
Emotet activity appeared to decline during December, but it sprung back to life in January – and it currently shows no signs of slowing down as researchers have detailed yet another campaign.

90% of UK Data Breaches Due to Human Error in 2019
Human error caused 90% of cyber data breaches in 2019, according to a CybSafe analysis of data from the UK Information Commissioner’s Office (ICO).
According to the cybersecurity awareness and data analysis firm, nine out of 10 of the 2376 cyber-breaches reported to the ICO last year were caused by mistakes made by end-users. This marked an increase from the previous two years, when respectively, 61% and 87% of cyber-breaches were ascribed to user error.
CybSafe cited phishing as the primary cause of breaches in 2019, accounting for 45% of all reports to the ICO. ‘Unauthorized access’ was the next most common cause of cyber-breaches in 2019, with reports relating to malware or ransomware, hardware/software misconfiguration and brute force password attacks also noted.

Police Warning: Cyber Criminals Are Using Cleaners to Hack Your Business
Criminal gangs are planting “sleepers” in cleaning companies so that they can physically access IT infrastructure, a senior police officer with responsibility for cyber crime has warned, urging businesses to bolster their physical security processes in the face of the growing threat.
Shelton Newsham, who manages the Yorkshire and Humber Regional Cyber Crime Team, told an audience at the SINET security event that he was seeing a “much larger increase in physical breaches” as cyber crime groups diversify how they attack and move laterally inside institutions.

The Mirai IoT botnet holds strong in 2020
The Mirai botnet has been a constant IoT security threat since it emerged in fall 2016. The subsequent release of its source code only extended Mirai's reach and is one of the many reasons it has been labelled the "king of IoT malware."
Mirai continues to be successful for a well-known reason: Its targets are IoT devices with hardcoded credentials found in a simple web search. Such devices listen for inbound telnet access on certain ports and have backdoors through which Mirai can enter. Once a device is subsumed in the botnet it immediately scans for other victims.

Governments Are Soft Targets for Cyber-criminals
New research has found that governments are more vulnerable to cyber-attacks than other organisations.
A report on the security of municipal governments and agencies identified three key factors that made governments particularly soft targets. Researchers found that governments had larger attack surfaces, lower usage rates of even the most basic email authentication schemes, and much higher rates of internal hosting than other organisations.
Government attack surfaces, consisting of open ports and applications, were found to be on average 33% larger than those risked by other organisations.

BYO Hardware Driver: New Ransomware Attacks Kernel Memory and brings its own vulnerability
A ransomware strain dubbed “RobbinHood” is using a vulnerability in a “legitimate” and signed hardware driver to delete security products from targeted computers before encrypting users files, according to security researchers.
The ransomware exploits a known vulnerability in the driver from Taiwan’s GIGABYTE to subvert a setting in kernel memory in Windows 10, 8 and 7, meaning it “brings its own vulnerability” and can attack otherwise patched systems.
