Black Arrow Cyber Threat Briefing 16 April 2021: 61% Of Employees Fail Basic Cyber Security Quiz; More Than 1,900 Hacking Groups Active Today; Ransomware Crisis Worsens; Enterprise Security Attackers Are One Password Away From Your Worst Day; Microsoft’s April Update Patches 114 Bugs; Nation-State Attacks Targeting Businesses Rise; Criminals Installing Cryptojacking Malware On Unpatched Exchange Servers; Network Vulns Affect Over 100 Million Devices; Brits Still Confused By Multi-Factor Authentication
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
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.

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.

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
Boards Still Aren't Taking Cyber Security Seriously, That Means Everyone Is At Risk
Cyber security still is not taken as seriously as it should be by boardroom executives – and that's leaving organisations open to cyber attacks, data breaches and ransomware, the new boss of the National Cyber Security Centre (NCSC) has warned. In her first speech since taking the helm of the UK cyber security agency, CEO Lindy Cameron said cyber security should be viewed with the same importance to CEOs as finance, legal or any other vital day-to-day part of the enterprise.
Nearly 40% Of New Ransomware Families Use Both Data Encryption And Data Theft In Attacks
2020 saw an explosion of ransomware that also steals data, giving the attackers more leverage over their victims. If organisations first refuse to pay a ransom to decrypt their data, attackers threaten to leak the stolen information, increasing pressure on victims to pay. This evolution, referred to as Ransomware 2.0 in the report, was a significant development in 2020. Only one ransomware group was observed using this type of extortion in 2019. By the end of 2020, 15 different ransomware families had adopted this approach. Furthermore, nearly 40% of ransomware families discovered in 2020, as well as several older families, were known to also steal data from victims by the end of last year.
https://www.helpnetsecurity.com/2021/03/31/ransomware-families-data-encryption/
Ransomware: Why We Are Now Facing A Perfect Storm
Ransomware is becoming more successful than ever before because of a combination of factors that allow cyber criminals to easily gain access to corporate networks – and they are finding success because a significant number of organisations that fall victim to attacks are willing to pay the ransom. A report warns that the 'perfect storm' of conditions have come together and allowed ransomware attacks to run rampant against organisations around the world.
https://www.zdnet.com/article/ransomware-why-were-now-facing-a-perfect-storm/
Ransomware: Nearly A Fifth Of Victims Who Pay Off Extortionists Fail To Get Their Data Back
The poll found that close to half (46%) of UK ransomware victims paid the ransom to restore access to their data last year, yet an unfortunate 11% of victims who shelled out did not have their stolen data returned. Whether they paid or not, only 18% of 1,006 UK victims surveyed were able to restore all their encrypted or blocked files following an attack. Internationally the picture is still worse with more than half (56%) paying off extortionists and nearly one in five of whom (17%) failing to get their data back even after paying out.
Billions Of Records Have Been Hacked Already. Make Cyber Security A Priority Or Risk Disaster
More data records have been compromised in 2020 alone than in the past 15 years combined, in what is described as a mounting "data breach crisis" in the latest study from analysis. Over the past 12 months, 31 billion data records have been compromised. This is up 171% from the previous year and constitutes well over half of the 55 billion data records that have been compromised in total since 2005.
Ransomware Gang Urges Victims’ Customers To Demand A Ransom Payment
A ransomware operation known as 'Clop' is applying maximum pressure on victims by emailing their customers and asking them to demand a ransom payment to protect their privacy. A common tactic used by ransomware operations is to steal unencrypted data before encrypting a victim's network. This data is then used in a double-extortion tactic where they threaten to release the data if a ransom is not paid.
Employee Lockdown Stress May Spark Cyber Security Risk
Stressed-out employees in a remote-working world could be a major contributor to poor cybersecurity postures for companies, according to a survey. Among other findings, the survey found that younger employees as well as people caring for children or other family members reported more stress in their lives, as well riskier IT behaviours when compared to other demographics. For instance, 67 percent of employees under 30 said they use shadow IT (unsanctioned apps, services, and equipment) to help them to perform certain tasks more easily, compared to 27 percent of older workers.
https://threatpost.com/employee-lockdown-stress-cybersecurity-risk/165050/
Shadow IT Is Your Organisation's Next Remote-Working Nightmare
Shadow IT refers to the use of devices, systems and software outside of those permitted by an organisational IT department. According to new research by software company Forcepoint, more than a third (37%) of UK employees are now relying on shadow IT at home, increasing companies' exposure to cyber security risks.
The use of personal devices appears to be one of the biggest culprits: 48% of respondents admitted to using their own devices to access work documents and corporate networks while working from home. Meanwhile, 34% of employees reported using private email or file-sharing cloud services for work purposes – again against the advice of employers.

Top Cyber Stories of the Last Week
Tens Of Thousands Of Microsoft Exchange Customers Are Under Assault From Hackers, Experts Warning Of Unprecedented Damage, Exploits Being Targeted By "At Least 10 Hacker Groups"
Four exploits in Microsoft Exchange Server hit the news last week, when we heard that a Chinese hacking group had targeted the email servers of some 30,000 U.S. government and commercial organisations. The exploits had been patched by Microsoft, but the hacking group known as “Hafnium” had doubled-up on efforts targeting unpatched servers. Security researchers found that at least 10 APT groups are taking advantage of the exploits in an attempt to compromise servers around the world. Winniti Group, Calypso, Tick, and more are among the groups identified.

Over $4.2 Billion Officially Lost To Cyber Crime In 2020
Cyber crime affecting victims in the U.S., noting a record number of complaints and financial losses in 2020 compared to the previous year. The Internet Crime Complaint Center (IC3) received last year 791,790 complaints - up by 69% from 2019 - of suspected internet crime causing more than $4 billion in losses. While most complaints were for phishing, non-payment/non-delivery scams, and extortion, about half of the losses are accounted by business email compromise (BEC), romance and confidence scams, and investment fraud.
Cyber Attacks Multiply On Wealthy Investors
An email nearly cost a wealthy British art collector £6m, after hackers monitored email correspondence between the client and an art dealer the client had been negotiating with for a year, with hackers impersonating the genuine art dealer, learning to impersonate the tone and language used — even gleaning private family news and the names of partners and children.
Just when the collector and the art dealer finally reached a conclusion on price, the client received an email to say something along the lines of, I hope the children are recovering from their colds — we have just amended our bank details for security and here they are. As it matched the tone of previous emails the art-loving client didn't think anything was amiss.
Fortunately, his family office phoned the real dealer to check the transaction before approving a transfer and the scam was discovered in time, but many people are not so lucky.

Cyber Strength Now Key To National Security, Says UK
In what has been billed as the largest security and foreign policy strategy revamp since the Cold War, the UK government has outlined new defence priorities – with at their heart, the imperative to boost the use of new technologies to safeguard the country. Prime minister Boris Johnson unveiled the integrated review this week, which has been in the making for over a year and will be used as a guide for spending decisions in the future. Focusing on foreign policy, defense and security, the review sets goals for the UK to 2025; and underpinning many of the targets is the objective of modernizing the country's armed forces.

Largest Ransomware Demand Now Stands At $30 Million As Crooks Get Bolder
Ransomware shows no sign of slowing down as the average ransom paid to cyber criminals by organisations that fall victim to these attacks has nearly tripled over the past year. Cyber security researchers analysed ransomware attacks targeting organisations across North America and Europe and found that the average ransom paid in exchange for a decryption key to unlock encrypted networks rose from $115,123 in 2019 to $312,493 in 2020.
Mimecast: SolarWinds Attackers Stole Source Code
Hackers who compromised Mimecast networks as part of the SolarWinds espionage campaign have swiped some of the security firm’s source code repositories, according to an update by the company. The email security firm initially reported that a certificate compromise in January was part of the sprawling SolarWinds supply-chain attack that also hit Microsoft, FireEye and several U.S. government agencies.

71 Percent Of Office 365 Users Suffer Malicious Account Takeovers
88 percent of companies have accelerated their cloud and digital transformation projects due to COVID-19. But it also finds that 71 percent of Microsoft Office 365 deployments have suffered an account takeover of a legitimate user's account, not just once, but on average seven times in the last year.
https://betanews.com/2021/03/17/office-365-malicious-account-takeovers/
More Than 16 Million Covid-Themed Cyber Attacks Launched In 2020
COVID-19 dominated everyone's lives throughout 2020 but a new report from a cyber security company found that the pandemic was also the main theme of nearly 16.5 million threats and attacks launched against its customers. Researchers wrote that they dealt with 16,393,564 threats that had a COVID-19-related tint to them, with 88% of the threats coming in spam emails and another 11% coming in the form of URLs. Malware accounted for 0.2%, or nearly 33,000, of the threats
“Expert” Hackers Used 11 0-Days To Infect Windows, iOS, And Android Users
Using novel exploitation and obfuscation techniques, a mastery of a wide range of vulnerability types, and a complex delivery infrastructure, the group exploited four zero-days in February 2020. The hackers’ ability to chain together multiple exploits that compromised fully patched Windows and Android devices led members of Google’s Project Zero and Threat Analysis Group to call the group “highly sophisticated.”
Cyber Attacks: Is The ‘Big One’ Coming Soon?
2020 was the year that the COVID-19 crisis also brought a cyber pandemic. Late last year, the security industry’s top experts from global cyber security company leadership predicted even worse cyber security outcomes for 2021 compared to what we saw in 2020. In December, we learned about how SolarWinds’ Orion vulnerability was compromised, causing one of the worst data breaches in history that is still evolving for about 18,000 organisations.
