Top Cyber Stories of the Last Week

World’s Biggest Meat Producer JBS Pays $11m Cyber Crime Ransom

JBS, the world’s biggest meat processor, has paid an $11m (£7.8m) ransom after a cyber attack shut down operations, including abattoirs in the US, Australia and Canada. While most of its operations have been restored, the Brazilian-headquartered company said it hoped the payment would head off any further complications including data theft. JBS, which supplies more than a fifth of all beef in the US, reportedly made the payment in bitcoin.

Jackware: A New Type Of Ransomware Could Be 10 Times As Dangerous

Between the attacks on Colonial Pipeline and JBS, which disrupted nearly half of the East Coast’s gasoline supply for a week and threatened 20% of the U.S. meat market, respectively, consumers are finally experiencing the first physical impacts to their daily lives from cyber attacks. As bad as these attacks are, they could get a lot worse. Cyber criminals are constantly evolving, and what is keeping many security professionals up at night is the growing risk of “jackware” — a new type of ransomware that could be 10 times more dangerous because instead of encrypting Windows computers and servers. Jackware hijacks the actual physical devices and machines that make modern life possible. It’s only a matter of when we will see these attacks happen

Lewd Phishing Lures Aimed At Business Explode

Attackers have amped up their use of X-rated phishing lures in business email compromise (BEC) attacks. A new report found a stunning 974-percent spike in social-engineering scams involving suggestive materials, usually aimed at male-sounding names within a company. The Threat Intelligence team with GreatHorn made the discovery and explained it’s not simply libido driving users to click on these suggestive scams. Instead, these emails popping up on people’s screens at work are intended to shock the user, opening the door for them to make a reckless decision to click. It’s a tactic GreatHorn called “dynamite phishing.”

UK Schools Forced To Shut Following Critical Ransomware Attack

Two schools in the south of England have been forced to temporarily close their doors after a ransomware attack that encrypted and stole sensitive data. The Skinners' Kent Academy and Skinners' Kent Primary School were attacked on June 2, according to a statement on the trust’s website which said it is currently working with third-party security experts, the police, and the National Cyber Security Centre (NCSC). It revealed that on-premises servers were targeted at the Tunbridge Well-based schools. As student and staff emergency contact details, medical records, timetables, and registers were encrypted by the attackers, the decision was taken to close on Monday.

Emerging Ransomware Targets Dozens Of Businesses Worldwide

An emerging ransomware strain in the threat landscape claims to have breached 30 organisations in just four months since it went operational by riding on the coattails of a notorious ransomware syndicate. First observed in February 2021, "Prometheus" is an offshoot of another well-known ransomware variant called Thanos, which was previously deployed against state-run organisations in the Middle East and North Africa last year. The affected entities are believed to be government, financial services, manufacturing, logistics, consulting, agriculture, healthcare services, insurance agencies, energy and law firms in the U.S., U.K., and a dozen more countries in Asia, Europe, the Middle East, and South America.

COVID-19 Has Transformed Work, But Cyber Security Is Not Keeping Pace, Report Finds

An international survey of tech professionals from the Thales Group finds some bleak news for the current state of data security: the COVID-19 pandemic has upended cyber security norms, and security teams are struggling to keep up. The problems appear to be snowballing; lack of preparation has led to a scramble resulting in poor data protection practices, outdated security infrastructure not receiving needed overhauls, a jumble of new systems that only make matters worse and priority misalignment between security teams and leadership.

Colonial Pipeline Ransomware Attack Was The Result Of An Old VPN Password

It took only one dusty, no-longer-used password for the DarkSide cyber criminals to breach the network of Colonial Pipeline Co. last month, resulting in a ransomware attack that caused significant disruption and remains under investigation by the U.S. government and cyber security experts. Attackers used the password to a VPN account that was no longer in use but still allowed them to remotely access Colonial Pipeline’s network, Charles Carmakal, senior vice president at FireEye’s cyber security consulting firm Mandiant, told Bloomberg in an interview, according to a published report on the news outlet’s website.

https://threatpost.com/darkside-pwned-colonial-with-old-vpn-password/166743/

Evil Corp Rebrands Ransomware To Escape Sanctions

Threat actors behind a notorious Russian cyber crime group appear to have rebranded their ransomware once again in a bid to escape US sanctions prohibiting victims from paying them. Experts took to Twitter to point out that a leak site previously run by the Babuk group, which famously attacked Washington DC’s Metropolitan Police Department (MPD), had rebranded to “PayloadBin.” The Babuk group claimed that it was shutting down its affiliate model for encrypting victims and moving to a new model back in April. A ‘new’ ransomware variant with the same name has also been doing the rounds of late, but according to CTO of Emsisoft, Fabian Wosar, it’s nothing more than a copycat effort by Evil Corp.

https://www.infosecurity-magazine.com/news/evil-corp-rebrands-ransomware/

Billions Of Passwords Leaked Online From Past Data Breaches

A list of leaked passwords discovered on a hacker forum may be one of the largest such collections of all time. A 100GB text file leaked by a user on a popular hacker forum contains 8.4 billion passwords, likely gathered from past data breaches.

Top Cyber Stories of the Last Week

Two Thirds Of CISOs Across World Expect Damaging Cyber Attack In Next 12 Months

More than 1,000 CISOs around the world have expressed concerns about the security ramifications of the massive shift to remote work since the beginning of the pandemic. One hundred CISOs from the US, Canada, the UK, France, Germany, Italy, Spain, Sweden, the Netherlands, UAE, Saudi Arabia, Australia, Japan, and Singapore were interviewed for the report, with many highlighting significant problems in the current cyber security landscape.

Ransomware: Don't Pay Up, It Just Shows Cyber Criminals That Attacks Work, Warns Home Secretary

For victims of ransomware attacks, paying the ransom does not guarantee that their network will be restored – and handing money to criminals only encourages them to try their luck infecting more companies with the file-encrypting malware. The impact of ransomware attacks continues to rise as cyber criminals encrypt networks, while also blackmailing victims with the prospect of stolen data being published, to generate as much money as possible from extortion.

The Most Significant Cyber Attacks From 2006-2020, By Country

Committing a cyber crime can have serious consequences. In the US, a cyber criminal can receive up to 20 years in prison for hacking into a government institution if it compromises national security. Yet, despite the consequences, cyber criminals continue to wreak havoc across the globe. But some countries seem to be targeted more than others. Using data from SpecOps Software, this graphic looks at the countries that have experienced the most significant cyber attacks over the last two decades.

The Shape Of Fraud And Cyber Crime: 10 Things We Learned From 2020

While it remains true that the older you are, the greater the financial loss, why would fraudsters target the young, who are arguably less well off? The answer lies in volume. Criminals have been offsetting higher monetary gain for higher attack rates, capitalising on the fact that the young are perhaps both more liberal with personal information (and privacy in general) and, at the same time, heavy digital users (social media, surveys, games, and so on). In fact, it is scary to see how much value the humble email address can have for criminals. We often forget that once obtained, it can be used further down the line to commit more fraud.

Is Third-Party Software Leaving You Vulnerable To Cyber Attacks?

When companies buy digital products, they expect them to be secure. In most cases, they do not test for vulnerabilities down the digital supply chain — and do not even have adequate processes or tools to do so. Hackers have taken note, and incidents of supply chain cyber attacks, which exploit weaknesses within the digital supply chain to break into organisations’ internal networks, are on the rise. As a result, there have been many headline incidents that not only bring shame to the companies involved, but rachet up the visibility of these threats to top executives who want to know their offerings are secure.

US Pipeline Ransomware Attack Serves As Fair Warning To Persistent Corporate Inertia Over Security

Organisations that continue to disregard the need to ensure they have adopted basic cyber security hygiene practices should be taken to task. This will be critical, especially as cyber criminals turn their attention to sectors where cyber threats can result in real-world risks, as demonstrated in the US Colonial Pipeline attack. In many of my conversations with cyber security experts, there is a shared sense of frustration that businesses still are failing to get some of the most basic things right. Default passwords are left unchanged, frontline staff and employees are still falling for common scams and phishing attacks, and major businesses think nothing of using technology that are decades old.

https://www.zdnet.com/article/us-pipeline-ransomware-attack-serves-as-fair-warning-to-persistent-corporate-inertia-over-security/

Ransomware Attackers Are Now Using Triple Extortion Tactics

The number of organisations affected by ransomware so far this year has more than doubled, compared with the same period in 2020, according to the report. Since April, Check Point researchers have observed an average of 1,000 organisations impacted by ransomware every week. For all of 2020, ransomware cost businesses worldwide around $20 billion, more than 75% higher than the amount in 2019. The healthcare sector has been seeing the highest volume of ransomware with around 109 attacks per organization each week. Amid news of a ransomware attack against gas pipeline company Colonial Pipeline, the utilities sector has experienced 59 attacks per organization per week. Organisations in the insurance and legal sector have been affected by 34 such attacks each week.

AXA Pledges To Stop Reimbursing Ransom Payments For French Ransomware Victims

Insurance company AXA has revealed that, at the request of French government officials, it will end cyber insurance policies in France that pay ransomware victims back for ransoms paid out to cyber criminals. While unconfirmed, the Associated Press reported that the move was an industry first. AXA is one of the five biggest insurers in Europe and made the decision as ransomware attacks become a daily occurrence for organisations across the world.

The Dystopic Future Of Cyber Security And The Importance Of Empowering CISOs

Over a decade ago, in 2007, the first iPhone was released and with it emerged an ecosystem of apps that continues to expand to this day. This was a watershed moment, not solely for the technology industry, but civilization. It was a catalyst for what was to come. Suddenly, every consumer could access the internet at a touch of a button, and the accumulation of their data by private companies began en masse. It was at this point that data was established as an increasingly valuable commodity, and in turn, became a heightened exploitation risk. It also instigated a wave of innovation that has yet to break and is only growing rapidly in pace. In this state, technology providers, users, and manufacturers get excited about new functionalities, new features, new developments, while little thought is given to the negative consequences that could arise as a result. Indeed, fear has no place in the state of innovation as it is this primal thinking that inhibits creativity.

Cyber Security Experts Warn Over Online Wine Scams

Online wine scams became a bigger threat as cyber criminals sought to take advantage of more people and businesses organising virtual drinks and ordering bottles on the internet in the wake of Covid-19 restrictions, suggests the report. So-called ‘phishing emails’ were a particular concern, according to findings published in April by US-based group Recorded Future in partnership with Area 1 Security. From January 2020 onwards, the authors found a significant rise in legitimate wine-themed web domain registrations using terms like Merlot, Pinot, Chardonnay or Vino.

Top Cyber Stories of the Last Week

61 Percent Of Employees Fail Basic Cyber Security Quiz

Nearly 70% of employees polled in a new survey said they recently received cyber security training from their employers, yet 61% nevertheless failed when asked to take a basic quiz on the topic. This was one of the leading findings of a research study that sought to understand the cyber security habits of some 1,200 workers, as well as their knowledge of best practices and ability to recognize security threats.

https://www.scmagazine.com/home/security-news/61-percent-of-employees-fail-basic-cybersecurity-quiz/

More Than 1,900 Distinct Hacking Groups Are Active Today

There are currently more than 1,900 distinct hacking groups that are active today, a number that grew from 1,800 groups recorded at the end of 2019. In its yearly cyber crime report, the company said it discovered 650 new threat actors during 2020, but new evidence also allowed it to remove 500 groups from its threat actor tracker due to overlaps in activity and hacking infrastructure with previously known clusters.

https://therecord.media/fireeye-more-than-1900-distinct-hacking-groups-are-active-today/

Ransomware: The Internet's Biggest Security Crisis Is Getting Worse

Organisations continue to fall victim to ransomware, and yet progress on tackling these attacks, which now constitute one of the biggest security problems on the internet, remains slow. From small companies to councils, government agencies and big business, the number and range of organisations hit by ransomware is rising. One recent example; schools with 36,000 students have been hit, leaving pupils without access to email as attempts were made to get systems back online. That is at least four chains of schools attacked in the last month.

Enterprise Security Attackers Are One Password Away From Your Worst Day

If the definition of insanity is doing the same thing over and over and expecting a different outcome, then one might say the cyber security industry is insane.

Criminals continue to innovate with highly sophisticated attack methods, but many security organisations still use the same technological approaches they did 10 years ago. The world has changed, but cyber security hasn’t kept pace.

Distributed systems, with people and data everywhere, mean the perimeter has disappeared. And the hackers couldn’t be more excited. The same technology approaches, like correlation rules, manual processes and reviewing alerts in isolation, do little more than remedy symptoms while hardly addressing the underlying problem.

Credentials are supposed to be the front gates of the castle, but as the SOC is failing to change, it is failing to detect. The cyber security industry must rethink its strategy to analyse how credentials are used and stop breaches before they become bigger problems.

Microsoft’s April Update Patches 114 Bugs—Half Of Which Allow Remote Code Execution

The fourth Patch Tuesday of 2021 is another big one. Today, Microsoft revealed 114 vulnerabilities fixed in the monthly security, over half of which could potentially be exploited for remote code execution by attackers. Of the 55 remote execution bugs, over half were tied to Windows’ Remote Procedure Call (RPC) interface. Four more were Microsoft Exchange bugs (all urgent fixes) reported to Microsoft by the National Security Agency. In addition, six Chrome vulnerabilities that were previously addressed by Google are included in the roll-up.

Nation-State Cyber Attacks Targeting Businesses Are On The Rise

Businesses are increasingly coming under fire from nation state-backed hackers as governments around the world engage in attacks to steal secrets or lay the foundations for future attacks. Nation States, Cyberconflict and the Web of Profit, a study by cyber security researchers at HP and criminologists at the University of Surrey, warns that the number of key nation-state attacks has risen significantly over the past three years – and that enterprises and businesses are increasingly being targeted. An analysis of nation-state cyber attacks between 2017 and 2020 reveals that just over a third of organisations targeted were businesses: cyber defence, media, government, and critical infrastructure are all also common targets in these attacks, but enterprise has risen to the top of the list.

Cyber Criminals Are Installing Cryptojacking Malware On Unpatched Microsoft Exchange Servers

Cyber criminals are targeting vulnerable Microsoft Exchange servers with cryptocurrency mining malware in a campaign designed to secretly use the processing power of compromised systems to make money. Zero-day vulnerabilities in Microsoft Exchange Server were detailed last month when Microsoft released critical security updates to prevent the exploitation of vulnerable systems. Cyber attackers ranging from nation-state-linked hacking groups to ransomware gangs have rushed to take advantage of unpatched Exchange servers -- but they are not the only ones.

NAME:WRECK DNS Vulnerabilities Affect Over 100 Million Devices

Security researchers have disclosed nine vulnerabilities affecting network communication stacks running on at least 100 million devices. Collectively referred to as NAME: WRECK, the flaws could be leveraged to take offline affected devices or to gain control over them. The vulnerabilities were found in a wide range of products, from high-performance servers and networking equipment to operational technology (OT) systems that monitor and control industrial equipment. According to researchers threat actors could exploit NAME:WRECK vulnerabilities to deal significant damage to government or enterprise servers, healthcare facilities, retailers, or companies in the manufacturing business by stealing sensitive data, modifying or taking equipment offline for sabotage purposes.

Brits Still Confused By Multi-Factor Authentication

The British public are still woefully underinformed and unaware of the security benefits of multi-factor authentication (MFA). The industry association, founded in 2012 to promote authentication standards and reduce global reliance on passwords, recently polled over 4000 consumers in the UK, France, Germany, and the US. It revealed that half (49%) UK consumers have had their social media accounts compromised or know a friend or family member who has. However, despite a continued number of high-profile account takeovers, 43% said this does not make them enhance security on their accounts, even though they “feel like” they should. Part of the problem seems to be a general lack of understanding about the benefits of MFA in protecting account holders from phishing, as well as credential stuffing and other brute force attack types. Although such features are offered by all social media companies today, over a quarter (26%) of respondents said they were not using or didn’t know about them.

623K Payment Cards Stolen From Cyber Crime Forum

The Swarmshop cyber underground “card shop” has been hit by hackers, who lifted the site’s database of stolen payment-card data and leaked it online. That is according to researchers, who said that the database was posted on a rival underground forum. Card shops, are online cyber criminal forums where stolen payment-card data is bought and sold. Researchers said the database in question contains 623,036 payment-card records from card-issuers in Brazil, Canada, China, France, Mexico, Saudi Arabia, Singapore, the U.K., and the U.S.

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.

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.

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.

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.

Ransomware accounted for 41% of all cyber insurance claims in H1 2020

Ransomware incidents have accounted for 41% of cyber insurance claims filed in the first half of 2020, according to a report published today by one of the largest providers of cyber insurance services in North America.

The high number of claims comes to confirm previous reports from multiple cyber-security firms that ransomware is one of today's most prevalent and destructive threats.

Ransomware doesn't discriminate by industry. An increase in ransom attacks has been seen across almost every industry.

In the first half of 2020 alone, they observed a 260% increase in the frequency of ransomware attacks amongst their policyholders, with the average ransom demand increasing 47%.

Among the most aggressive gangs, the cyber insurer listed Maze and DoppelPaymer, which have recently begun exfiltrating data from hacked networks, and threatening to release data on specialized leak sites, as part of double extortion schemes.

Why this matters:

Ransomware remains, and is likely to remain, by far one of the biggest menaces on the web, it is indiscriminate, anyone can be affected, it can be business destroying, and it is getting worse all the time.

Microsoft’s Patch Tuesday Packed with Critical RCE Bugs

Microsoft has released patches for 129 security bugs in its September Patch Tuesday update. These include 23 critical flaws, 105 that are important in severity and one moderate bug. Fortunately, none are publicly known or under active exploitation, Microsoft said.

The most severe issue in the bunch is CVE-2020-16875, according to researchers. This is a memory-corruption problem in Microsoft Exchange that allows remote code-execution (RCE) just by sending an email to a target. Running arbitrary code could grant attackers the access they need to create new accounts, access, modify or remove data, and install programs.

Why this matters:

Many organisations are struggling to keep up with the volume of updates and keeping on top of them, or knowing which to prioritise, is critical for firms. At a time while many organisations continue to struggle to support the ongoing distribution of remote workers, Microsoft continues to pile on the updates and finding an efficient method for rolling out these patches has become even more imperative as companies begin to abandon the idea of a short-term fix and shift operations to embrace remote work as part of a lasting, long-term progression of how organisations operate moving forward.

Firms are beginning to realise the negative outcomes of the lenient security measures put in place to quickly adapt to a decentralised workforce and it’s become more important than ever to establish patching policies that can securely support remote endpoints for the foreseeable future.

60 percent of emails in May and June were fraudulent

The COVID-19 pandemic has seen a spike in scams, phishing and malware across all platforms and attack vectors. The latest mid-year threat landscape report from Bitdefender shows that in May and June, an average of 60 percent of all received emails were fraudulent.

In addition there’s been a five-fold increase in the number of coronavirus-themed attacks and a 46 percent increase in attacks aimed at home IoT devices.

IoT malware has become versatile, robust, and is constantly updated. IrcFlu, Dark_Nexus7 and InterPLanetary Storm are some of the examples malware that gained in popularity during the first half of 2020.

Mobile malware has been quick to capitalise too, with malware developers rushing to weaponise popular applications, such as the Zoom video conferencing application, used by employees now working from home. Packing RAT (Remote Access Trojan) capabilities, or bundling them with ransomware, banking malware, or even highly aggressive adware, Android malware developers were also fully exploiting the pandemic wave.

Why this matters:

As we keep saying malicious actors never let a good crisis or tragedy go to waste and will exploit whatever is going on in the world or anything there is a collective interest in to real in unsuspecting victims.

Good awareness and education are key in keeping your employees and users safe and ensuring users at all levels, including board members – who present a significant risk, are up to date with latest tactics and threats.

Email in particular will remain primary vector for attack and this is unlikely to change any time soon.

Businesses [should] Fear Insider-Enabled Data Breaches

Businesses fear suffering a data breach and expect it to be caused by an insider or internal error.

A survey of 500 IT professionals found that 94% of respondents have experienced a data breach, and 79% were worried their organisation could be next.

The fear associated with breaches stems from the security culture within the organisation, along with the security reporting structure.

Having security teams in close dialogue with executive leadership, supporting the leadership to make informed risk-based decisions and driving the business strategy, including the technologies used, reduces this fear significantly.

Secondly, not understanding information security, its components and principles drives fear and anxiety of the unknown, so having security education training, and developing awareness and consciousness of threats, will enable and empower the entire organisation to act with a ‘security first’ mindset.

Finally, recognising the importance of access control to protect systems and data is a foundational level control that organisations can apply to reduce the risk of a data breach. Hand in hand with this is partnering with trusted identity and access control platform providers who can provide enterprises with that security expertise and industry leadership.

Why this matters:

In terms of what is causing the breaches, 40% of respondents to the survey said accidental employee incidents were to blame, compared to 21% who said it is external attackers. Asked if this is a case of businesses not having a handle on what leaves their organisations (either intentionally or accidentally), insiders already have access and can leave with data invisibly, which might turn up somewhere embarrassing later.

4 top vulnerabilities ransomware attackers exploited in 2020

As more employees work from home, attackers have more endpoints to target. These unpatched vulnerabilities in remote access tools and Windows makes their job easier.

The biggest security trend for 2020 has been the increase of COVID-19-related phishing and other attacks targeting remote workers. New York City, for example, has gone from having to protect 80,000 endpoints to around 750,000 endpoints in its threat management since work-from-home edicts took place.

As noted in a recent Check Point Software Technologies mid-year review, “The first impact of the pandemic was the proliferation of malware attacks that used social engineering techniques with COVID-19 thematic lures for the delivery stage.”  Domain names were set up and parked with names relating to the pandemic. As workers started to use videoconferencing platforms, attacks moved to attacking Zoom, Teams and other videoconferencing platforms.

One disturbing trend is that 80% of the observed attacks in the first half of 2020 used vulnerabilities reported and registered in 2017 and earlier, according to the Check Point report, and more than 20% of the attacks used vulnerabilities that are at least seven years old. This showcases that we have a problem in keeping our software up to date.

Why this matters:

Ransomware remains a big threat 2020 and expanding attack surfaces with staff working from home is making the situation worse. Attackers use vulnerabilities in tools used for remote access into Windows networks.

Click read more below to find out the top four vulnerabilities the researchers identified.

APT Groups Increasingly Targeting Linux-Based Devices

APT groups are increasingly executing targeted attacks against Linux-based devices as well as developing more Linux-focused tools, according to an investigation by Kaspersky.

This is as a result of a growing number of organisations’ selecting Linux ahead of Windows to run their strategically important servers and systems, and the perception that the Linux operating system is safer and less likely to be targeted by malware as it is less popular.

However, threat-actors have been observed to adapt their tactics to take advantage of this trend, and Kaspersky noted that “over a dozen APT actors have been observed to use Linux malware or some Linux-based modules” during the past eight years.

These include notorious groups such as Turla, Lazarus, Barium, Sofacy, the Lamberts and Equation. Kaspersky highlighted the example of Russian speaking APT group Turla using Linux backdoors as part of its changing toolset in recent years.

Why this matters:

Attacks that target Linux-based systems are still fewer in number than attacks on Windows based systems, but there is still malware designed to target them, including webshells, backdoors, rootkits and even custom-made exploits.

Major Chilean bank shuts down all branches following ransomware attack

Banco Estado, the only public bank in Chile and one of the three largest in the country, had to shut down its nationwide operations on Monday due to a cyberattack that turned out to be a ransomware launched by REvil.

According to a public statement, the branches will remain closed for at least one day, but clarified that customers’ funds have not been affected by the incident.

Sources close to the investigation reported that the REvil ransomware gang is behind the attack. It reportedly originated from an Office document infected with the malware that an employee received and proceeded to open.

The incident was reported to the Chilean authorities, who issued a cyber-security alert that warned about a massive ransomware campaign targeting the private sector in the country.

Why this matters:

As above ransomware is not going away and is getting worse all the time. Too many users don’t realise that simply opening a document or clicking on a link in an email could bring down their entire organisations. Staff and users need to be educated about the role they play in securing their organisations.

Vulnerabilities discovered in PAN-OS, which powers Palo Alto Networks’ firewalls

Palo Alto Networks this week remediated vulnerabilities in PAN-OS (operating systems version 8.1 or later) which command injection, cross site scripting and the ability to upload unauhtoised files to a directory which might lead to denial of service.

Why this matters:

Attackers can use these vulnerabilities to gain access to sensitive data or develop the attack to gain access to the internal segments of the network of a company that uses vulnerable protection tools.

Any security fixes for known vulnerabilities across any different product, software or firmware should be tested and applied as soon as possible, so those vulnerabilities cannot be used against you or your organisation.

Russia, China and Iran hackers target Trump and Biden, Microsoft says

Hackers with ties to Russia, China and Iran are attempting to snoop on people and groups involved with the US 2020 presidential election, Microsoft says.

The Russian hackers who breached the 2016 Democratic campaign are again involved, said the US tech firm.

Microsoft said it was "clear that foreign activity groups have stepped up their efforts" targeting the election.

Both President Donald Trump and Democrat Joe Biden's campaigns are in the cyber-raiders' sights.

Russian hackers from the Strontium group have targeted more than 200 organisations, many of which are linked to US political parties - both Republicans and Democrats, Microsoft said in a statement.

Why this matters:

The same attackers have also targeted British political parties, said Microsoft, without specifying which ones. Any meddling in politics by foreign states is a clear threat to the democratic process and shows that unfriendly states will interfere to further their own agendas.

TikTok battles to remove video of livestreamed suicide

TikTok is battling to remove a graphic video of a livestreamed suicide, after the footage was uploaded to the service on Sunday night from Facebook, where it was initially broadcast.

Although the footage was rapidly taken down from TikTok, users spent much of Monday re-uploading it, initially unchanged, but later incorporated into so-called bait-and-switch videos, which are designed to shock and upset unsuspecting users.

One such video, for instance, begins with a conventional video of an influencer talking to camera, before cutting without warning to the graphic footage.

Why this matters:

Parents, especially of younger children, may think that certain sites and social media channels are safe for children and the content is suitable vetted and controlled, but as this illustrates that is often not the case and caution should be exercised in allow young children unfettered access to social media.

Travelex Forced into Administration After Ransomware Attack

Ransomware victim Travelex has been forced into administration, with the loss of over 1000 jobs.

PwC announced late last week that it had been appointed joint administrators of the currency exchange business.

The Sodinokibi (REvil) ransomware variant is believed to have struck the firm on New Year’s Eve last year, forcing its website offline and impacting its bricks-and-mortar stores and banking services. It took until January 17 for the firm to get its first customer-facing systems live again in the UK.

Why this matters:

Firms of any size can call victim to ransomware and many firms will not survive a significant cyber event such as this. Unconfirmed reports at the time suggested that a critical unpatched vulnerability in a VPN (Virtual Private Network) may have allowed attackers to remotely execute malicious code. A security researcher said he reached out to the firm in September 2019 to flag the issue but was ignored. This again shows the importance of ensuring all security updates are applied quickly. Has this software had the security updates applied those vulnerabilities would not have been able to be used in this attack.

Microsoft August 2020 Patch Tuesday fixes 120 vulnerabilities, two zero-days

Microsoft’s August 2020 Patch Tuesday security updates fell this week and this month the company has patched 120 vulnerabilities across 13 different products, from Edge to Windows, and from SQL Server to the .NET Framework.

Among these 120 vulnerabilities, 17 bugs have received the highest severity rating of "Critical," and there are also two zero-days — vulnerabilities that have been exploited by hackers before Microsoft was able to provide a fix.

Why this matters:

All security updates should be applied as soon as possible to prevent vulnerabilities from being exploited in attacks. When vulnerabilities are announced criminals will waste no time in weaponizing them (creating exploits to use in attacks) so the quicker the vulnerabilities are closed the safer you will be.

More ransomware victims are paying up, even when data recovery is possible

The proportion of ransomware attack victims actually paying ransoms increased in the last quarter, even in instances where ransomed data could be recovered, new figures have revealed.

According to a commercial ransomware recovery service, data exfiltration attacks are becoming more common and blending with traditional ransomware hacks. Data exfiltration extortion involves an attacker taking possession of stolen data and putting it up for sale on forums or marketplaces. Once monetised, the hacker asks the victim to pay a ransom to prevent the information’s release.

The recover firm added that tools currently on the market vary wildly when it comes to data recovery success following a ransomware attack. What’s more, the company has noted an uptick in the number of companies experiencing operating system and registry corruption even after ransomed data is restored.

Why this matters:

It used to be that backups were the best defence against ransomware attacks, but if your data is stolen a backup won’t help you avoid having to pay out to keep your sensitive or confidential data out of the public domain.

Intel, SAP, and Citrix release critical security updates

Intel released 18 advisories, including fixes for Denial of Service, Information Disclosure and Elevation of Privilege flaws affecting various products on Windows, Chrome OS and Linux OS.

SAP’s released 15 security notes and an update to a previously released one to address flaws in a variety of offerings, including SAP ERP, SAP Business Objects Business Intelligence Platform, SAP S/4 HANA and various SAP NetWeaver components.

Citrix’s has released patches for a set of vulnerabilities in certain on-premises instances of Citrix Endpoint Management (aka XenMobile Server).

Why this matters:

Security upgrades should always be applied as soon as possible. Whether announced vulnerabilities are already being exploited or not as they become known they likely will be exploited and patching them (applied the fixes made available) prevent them from being exploited.

IT Pros Name Misconfiguration #1 Cloud Security Threat

Configuration errors are the number one threat to cloud security, according to a new poll of IT and security professionals.

A security vendor interviewed 653 industry professionals to compile its 2020 Cloud Security Report.

Three-quarters (75%) claimed to be “very” or “extremely” concerned about cloud security, with most (52%) believing that the risks are higher in the public cloud than on-premises.

The top four threats were cited as: misconfiguration (68%), unauthorized cloud access (58%), insecure interfaces (52%), and account hijacking (50%).

These security concerns have created multiple barriers to further adoption of cloud services. The top inhibitor of adoption was a lack of qualified staff (55%), up from fifth place last year.

This may go some way to explaining respondents’ concerns around configuration errors, especially as 68% of these organisations are using two or more public cloud providers — adding to the complexity.

Why this matters?

Organisations’ cloud migrations and deployments are racing ahead of their security teams’ abilities to defend them against attacks and breaches. Their existing security solutions only provide limited protections against cloud threats, and teams often lack the expertise needed to improve security and compliance processes

RedCurl cybercrime group has hacked companies for three years

Security researchers have uncovered a new Russian-speaking hacking group that they claim has been focusing on the past three years on corporate espionage, targeting companies across the world to steal documents that contain commercial secrets and employee personal data.

Named RedCurl, the activities of this new group have been detailed in a 57-page report released this week.

Researchers have been tracking the group since the summer of 2019 and have since identified 26 other RedCurl attacks, carried out against 14 organisations, going as far back as 2018.

Why this matters:

This Russian group have targeted victims across different countries and industry sectors, and included construction companies, retailers, travel agencies, insurance companies, banks, and law and consulting firms from countries like Russia, Ukraine, Canada, Germany, Norway, and the UK. Many firms could fall victim to cyber crime groups like this if their defences are not able to withstand such attackers.

Why You Must Beware What You Ask Amazon Alexa

The same cyber team that cracked open TikTok, WhatsApp, Microsoft’s cloud and even Philips lightbulbs has just turned its attention to Amazon’s Alexa. And, unsurprisingly, it hasn’t disappointed. After “speculating” that Amazon’s 200 million devices “could be a prime entry-point for hackers,” Check Point Research has just lifted the lid to unmask “serious security flaws in Alexa.” According to the team, “in just one click, a user could have given up their voice history, home address and control of their Amazon account.”

Why this matters:

Warnings about the dangers of smart speakers and their extended families of virtual assistants are not new. These are the same devices that causes such scandal last year, when it transpired humans were listening to conversations to better train the AI. The issue here is different, much more akin to the broader problem of IoT security. Every different gadget you connect to the internet becomes a potential vulnerability and the methods needed to crack Amazon’s devices were not particularly sophisticated.

Ex-Uber engineer sentenced to 18 months in prison for stealing driverless car secrets from Google

A star engineer who admitted stealing self-driving car secrets from Google has been sentenced to 18 months in prison.

Anthony Levandowski, who helped found Google's self-driving car project, now known as Waymo, pleaded guilty to downloading documents containing data about the company's work and accessing one of them after he had left to found his own trucking startup.

Sentencing him in a San Francisco court, the judge said he was imposing prison time as a deterrent.

An early star in the self-driving car scene, Mr Levandowski pushed for Google to develop the technology but later became disillusioned, leaving in early 2016 to start trucking company Otto, which was bought by Uber less than eight months later. 

Waymo sued Uber, a case which was settled in 2018, with Uber paying out $245m (£187m) in equity and agreeing not to use its technology.

Uber had signed an indemnification agreement with Mr Levandowski, forcing it to pay his legal fees, but has refused to pay a $179m debt he owes to the Google spin-out, a consequence of separate legal action relating to his departure. 

Why this matters:

Your staff present one of your biggest risks, and a disgruntled or disillusioned employee can be very dangerous. The theft of intellectual property for personal gain is a classic example of this kind of behaviour. Data Loss Prevention (DLP) systems can help to spot unusual behaviour in employees and detect sensitive data being extracted from corporate systems.

Google and Amazon are now the most imitated brands for phishing

You may want to think twice about opening that email claiming to be from Google or Amazon, after new research found the tech giants were being used as lures for phishing scams.

Earlier this year, Check Point revealed that Apple was the most imitated brand for phishing, but over the course of the last few months, the iPhone maker has fallen to seventh place with Google and Amazon now taking the top spots.

Why this matters:

Phishing is estimated to be the starting point of over 90 percent of all cyberattacks and according to Verizon's 2019 Data Breach Investigations Report, nearly one third (32%) of all data breaches involved phishing activity. Additionally phishing was present in 78 percent of cyber espionage incidents and the installation and use of backdoors in company networks.

Cyber-Attacks on UK Organisations Up 30% in Q1 2020

New research has revealed that the volume of cyber-attacks on UK businesses increased by almost a third in the first three months of 2020.

Analysts identified 394,000 unique IP addresses used to attack UK businesses in the first quarter of 2020, discovering that companies with internet connections experienced 157,000 attacks each, on average – the equivalent of more than one a minute.

This rate of attack was 30% higher than the same period in 2019 when UK businesses received 120,000 internet-borne attempts to breach their systems each.

IoT applications were cited as the most common targets for cyber-criminals in the first quarter, attracting almost 19,000 online attacks per company. Company databases and file-sharing systems were also targeted frequently, with companies experiencing approximately 5000 attacks for each application, on average.

COVID-19 blamed for 238% surge in cyber attacks against banks

The coronavirus pandemic has been connected to a 238% surge in cyber attacks against banks, new research claims.

On Thursday, VMware Carbon Black released the third edition of the Modern Bank Heists report, which says that financial organizations experienced a massive uptick in cyber attack attempts between February and April this year -- the same months in which COVID-19 began to spread rapidly across the globe.  

The cyber security firm's research, which includes input from 25 CIOS at major financial institutions, adds that 80% of firms surveyed have experienced more cyber attacks over the past 12 months, an increase of 13% year-over-year.

VMware Carbon Black data already indicates that close to a third -- 27% -- of all cyber attacks target either banks or the healthcare sector.

An interesting point in the report is how there appears to have been an uptick in financially-motivated attacks around pinnacles in the news cycle, such as when the US confirmed its first case of COVID-19.

In total, 82% of chief information officers contributing to the report said that alongside a spike in attacks, techniques also appear to be improving -- including the use of social engineering and more advanced tactics to exploit not only the human factor but also weak links caused by processes and technologies in use by the supply chain.

Thunderbolt flaw ‘Thunderspy’ allows access to a PC’s data in minutes

Vulnerabilities discovered in the Thunderbolt connection standard could allow hackers to access the contents of a locked laptop’s hard drive within minutes, a security researcher from the Eindhoven University of Technology has announced. Reports state that the vulnerabilities affect all Thunderbolt-enabled PCs manufactured before 2019.

Although hackers need physical access to a Windows or Linux computer to exploit the flaws, they could theoretically gain access to all data in about five minutes even if the laptop is locked, password protected, and has an encrypted hard drive. The entire process can reportedly be completed with a series of off-the-shelf components costing just a few hundred dollars. Perhaps most worryingly, the researcher says the flaws cannot be patched in software, and that a hardware redesign will be needed to completely fix the issues.

A hacker group is selling more than 73 million user records on the dark web

A hacker group going by the name of ShinyHunters claims to have breached ten companies and is currently selling their respective user databases on a dark web marketplace for illegal products.

The hackers are the same group who breached last week Tokopedia, Indonesia's largest online store. Hackers initially leaked 15 million user records online, for free, but later put the company's entire database of 91 million user records on sale for $5,000.

Encouraged and emboldened by the profits from the Tokopedia sale, the same group has, over the course of the current week, listed the databases of 10 more companies.

This includes user databases allegedly stolen from organizations such as:

·         Online dating app Zoosk (30 million user records)

·         Printing service Chatbooks (15 million user records)

·         South Korean fashion platform SocialShare (6 million user records)

·         Food delivery service Home Chef (8 million user records)

·         Online marketplace Minted (5 million user records)

·         Online newspaper Chronicle of Higher Education (3 million user records)

·         South Korean furniture magazine GGuMim (2 million user records)

·         Health magazine Mindful (2 million user records)

·         Indonesia online store Bhinneka (1.2 million user records)

·         US newspaper StarTribune (1 million user records)

The listed databases total for 73.2 million user records, which the hacker is selling for around $18,000, with each database sold separately.

A cybercrime store is selling access to more than 43,000 hacked servers

MagBo, a shadowy online marketplace where hackers sell and buy hacked servers, is doing better than ever and has soared in popularity to become the largest criminal marketplace of its kind since its launch in the summer of 2018.

Two years later, the MagBo portal has grown more than 14 times in size and is currently selling access to more than 43,000 hacked websites, up from the 3,000 sites listed in September 2018.

Today, MagBo has become the de-facto go-to marketplace for many cybercrime operations. Some groups register on the MagBo platform to sell hacked servers, while others are there just to buy.

Those who buy, do it either in bulk (for black-hat SEO or for malware distribution) or selectively, for intrusions at high-value target (e-commerce stores for web skimming, intranets for ransomware).

All in all, the MagBo platform cannot be ignored anymore, as it appears to be here to stay, and is placing itself at the heart of many of today's cybercrime operations.

Ransomware: Why paying the crooks can actually cost you more in the long run

Ransomware is so dangerous because in many cases the victim doesn't feel like they have any other option other than to pay up – especially if the alternative is the whole organisation being out of operation for weeks, or even months, as it attempts to rebuild the network from scratch.

But handing over a bitcoin ransom to cyber criminals can actually double the cost of recovery according to analysis by researchers at Sophos, published in the new State of Ransomware 2020 report, which has been released three years to the day from the start of the global WannaCry ransomware outbreak.

A survey of organisations affected by ransomware attacks found that the average total cost of a ransomware attack for organisations that paid the ransom is almost $1.4m, while for those who didn't give into ransom demands, the average cost is half of that, coming in at $732,000.

Often, this is because retrieving the encryption key from the attackers isn't a simple fix for the mess they created, meaning that not only does the organisation pay out a ransom, they also have additional costs around restoring the network when some portions of it are still locked down after the cyber criminals have taken their money.

According to the report, one in four organisations said they paid the ransom in order to get their files back. It's one of the key reasons why ransomware remains a successful tactic for crooks, because victims pay up – often sums of six-figures or more – and are therefore encouraging cyber criminals to continue with attacks that often can't be traced back to a culprit.

This powerful Android malware stayed hidden for years, infecting tens of thousands of smartphones

A carefully managed hacking and espionage campaign is infecting smartphones with a potent form of Android malware, providing those behind it with total control of the device, while also remaining completely hidden from the user.

Mandrake spyware abuses legitimate Android functions to help gain access to everything on the compromised device in attacks that can gather almost any information about the user.

The attacker can browse and collect all data on the device, steal account credentials for accounts including banking applications. secretly take recordings of activity on the screen, track the GPS location of the user and more, all while continuously covering their tracks.

The full capabilities of Mandrake – which has been observed targeting users across Europe and the Americas – are detailed in a paper released by cybersecurity researchers this week. Mandrake has been active since 2016 and researchers previously detailed how the spyware operation was specifically targeting Australian users – but now it's targeting victims around the world.

Companies wrestle with growing cyber security threat: their own employees

Businesses deploy analytic tools to monitor staff as remote working increases data breach risk

As cyber criminals and hackers ramp up their attacks on businesses amid coronavirus-related disruption, companies are also facing another equally grave security threat: their own employees. 

Companies are increasingly turning to Big Brother-style surveillance tools to stop staff from leaking or stealing sensitive data, as millions work away from the watchful eyes of their bosses and waves of job cuts leave some workers disgruntled.

In particular, a brisk market has sprung up for cyber security groups that wield machine learning and analytics to crunch data on employees’ activity and proactively flag worrying behaviours.

Cognizant: Ransomware Costs Could Reach $70m

IT services giant Cognizant has admitted that a ransomware attack it suffered back in April may end up costing the company as much as $70m.

The firm announced revenue of $4.2bn for the first quarter of 2020, an increase of 2.8% year-on-year. In this context, the $50-70m hit it expects to take in Q2 from the ransomware attack will not make a huge impact on the company.

However, the big numbers involved are illustrative of the persistent financial threat posed by ransomware, not to mention the reputational impact on customers.

The firm claimed on an earnings call that the company responded immediately to the threat, proactively taking systems offline after some internal assets were compromised. However, the resulting downtime and suspension of some customer accounts took their toll financially.

“Some clients opted to suspend our access to their networks,” they explained. “Billing was therefore impacted for a period of time, yet the cost of staffing these projects remained on our books.”

Remote workers were also affected as the attack hit the firm’s system for supporting its distributed workforce during the current pandemic.

Package delivery giant Pitney Bowes confirms second ransomware attack in 7 months

Package and mail delivery giant Pitney Bowes has suffered a second ransomware attack in the past seven months, ZDNet has learned.

The incident came to light earlier in the week after a ransomware gang known as Maze published a blog post claiming to have breached and encrypted the company's network.

The Maze crew provided proof of access in the form of 11 screenshots portraying directory listings from inside the company's computer network.

Pitney Bowes confirmed the incident stating they had detected a security incident related to Maze ransomware.

The company said it worked with third-party security consultants to take steps to stop the attack before any of its data was encrypted.

This is the second ransomware incident for Pitney Bowes in seven months.

In October 2019, Pitney Bowes disclosed a first ransomware attack. At the time, the company said it had some critical systems infected and encrypted by the Ryuk ransomware gang. The incident caused limited downtime to some package tracking systems.

Both the Ryuk and Maze ransomware gangs are what experts call "human-operated" ransomware strains. These types of ransomware infections take place after hackers breach a company's network, and take manual control of the malware to expand access to as many internal systems as possible before executing the actual ransomware to encrypt data and demand a ransom.

Law Firm Representing Drake, Lady Gaga, Madonna And More Hit By Cyber Attack As Hackers Claim To Have Stolen Personal Information And Contracts

A law firm representing many of the world's most famous celebrities has been hacked.

The website of Grubman Shire Meiselas & Sacks has been taken offline, and hackers claim to have stolen some 756GB of data relating to its clients.

Singers, actors and other stars have worked with the law firm, according to old versions of its website, with more than 200 very high-profile celebrities and companies said to have used its services.

They include Madonna, Lady Gaga, Elton John and Drake.

The hackers behind the attack claim to have person information on celebrities including letters, as well as official contracts.

Hackers have already released a purported screenshot of a Madonna contract in an attempt to prove they have access to personal files.

It is not known what the hackers are demanding in return for the files, or whether negotiations are ongoing.

"We can confirm that we've been victimised by a cyber-attack," the firm said in a media statement. "We have notified our clients and our staff.

"We have hired the world's experts who specialise in this area, and we are working around the clock to address these matters."

The hack used a piece of software known as REvil or Sodinokibi. Similar software took foreign exchange company Travelex offline in January, as part of a major hack.

Traditionally, such ransomware has been used to lock down computers and demand money from their owners to unlock them again, and grant access to files.

Increasingly, hackers threaten to release those files to the public if their demands are not met.

Lights stay on despite cyber-attack on UK's electricity system

Britain’s energy system has fallen victim to a cyber-attack targeting the IT infrastructure used to run the electricity market.

The electricity system’s administrator, Elexon, confirmed that it was affected by a cyber-attack on Thursday afternoon but that the key systems used to govern the electricity market were not affected.

National Grid is investigating whether the attack could affect the part of its business tasked with keeping the lights on.

A spokesman for the energy system operator said electricity supplies had not been affected, and there were “robust cybersecurity measures in place” to make sure the UK continues to receive reliable electricity.

“We’re aware of a cyber intrusion on Elexon’s internal IT systems. We’re investigating the matter and any potential impact on our own IT networks,” he said.

Elexon is a vital part of the UK electricity market because it carefully monitors the electricity generated by energy companies to match this with what National Grid expects to receive, and to make sure that generators are paid the correct amount for the energy they generate.

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.

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.

Android malware can steal Google Authenticator 2FA codes

A new version of the "Cerberus" Android banking trojan will be able to steal one-time codes generated by the Google Authenticator app and bypass 2FA-protected accounts.

Security researchers say that an Android malware strain can now extract and steal one-time passcodes (OTP) generated through Google Authenticator, a mobile app that's used as a two-factor authentication (2FA) layer for many online accounts.

Google launched the Authenticator mobile app in 2010. The app works by generating six to eight-digits-long unique codes that users must enter in login forms while trying to access online accounts.

Google launched Authenticator as an alternative to SMS-based one-time passcodes. Because Google Authenticator codes are generated on a user's smartphone and never travel through insecure mobile networks, online accounts who use Authenticator codes as 2FA layers are considered more secure than those protected by SMS-based codes.

Ransomware victims thought their backups were safe. They were wrong

Ransomware victims are finding out too late that their vital backups are online and also getting encrypted by crooks, warns cyber security agency.

The UK's cyber security agency has updated its guidance on what to do after a ransomware attack, following a series of incidents where organisations were hit with ransomware, but also had their backups encrypted because they had left them connected to their networks.

Keeping a backup copy of vital data is a good way of reducing the damage of a ransomware attack: it allows companies to get systems up and running again without having to pay off the crooks. But that backup data isn't much good if it's also infected with ransomware -- and thus encrypted and unusable -- because it was still connected to the network when the attack took place.

The UK's National Cyber Security Centre (NCSC) said it has now updated its guidance by emphasising offline backups as a defence against ransomware.

Data breach at City watchdog FCA exposes records of thousands of complainants

The records of 1,600 people who complained to the City watchdog have been exposed following a major data breach at the regulator.

The Financial Conduct Authority (FCA) mistakenly published the personal records of complainants on its website, where anyone could access the information.

The data was visible between November 2019 and February 2020 and included the records of people who made a complaint between January 2018 and July 2019.

This leaked information included the name of the complainant, the company they represent, the status of the complaint and other information. In some instances addresses and telephone numbers were also visible.

Certain media outlets disclosed that the list contained the names of several high-profile individuals.

Hackers are getting better at tricking people into handing over passwords — here's what to look out for, according to experts

Hackers don't break in, they log in.

That mantra, often repeated by security experts, represents a rule of thumb: The vast majority of breaches are the result of stolen passwords, not high-tech hacking tools.

These break-ins are on the rise. Phishing scams — in which attackers pose as a trustworthy party to trick people into handing over personal details or account information — were the most common type of internet crime last year, according to a recent FBI report. People lost more than $57.8 million in 2019 as the result of phishing, according to the report, with over 114,000 victims targeted in the US.

And as phishing becomes more profitable, hackers are becoming increasingly sophisticated in the methods they use to steal passwords, according to Microsoft's Security Research team.

Most of the attackers have now moved to phishing because it's easy

Government authorities fail to train employees on ransomware detection, prevention

New research suggests that the majority of state and local governments are not rising to the challenge of mitigating ransomware threats. (and it’s not just Government)

The majority of state and local government agencies are failing to prepare their employees to spot cyber attacks or teach them how to handle ransomware incidents in the workplace, new research suggests.

On Thursday, IBM Security released the results of a new study, conducted on its behalf by The Harris Poll, containing responses from close to 700 US local and state employees in IT, education, emergency services, and security departments.

The research, taking place between January and February this year, reveals that only 38% of local and state employees have received any training in general ransomware prevention, which may include learning how to spot phishing attempts, the threat of social engineering, and basic security hygiene in the workplace.
