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

  • Ransomware Is the Biggest Global Cyber Threat. And The Attacks Are Still Evolving

Ransomware is the biggest cyber security threat facing the world today, with the potential to significantly affect whole societies and economies – and the attacks are unrelenting, the head of the National Cyber Security Centre (NCSC) has warned.

"Even with a war raging in Ukraine – the biggest global cyber threat we still face is ransomware. That tells you something of the scale of the problem. Ransomware attacks strike hard and fast. They are evolving rapidly, they are all-pervasive, they're increasingly offered by gangs as a service, lowering the bar for entry into cyber crime," said Lindy Cameron, CEO of the NCSC in a speech at Tel Aviv Cyber Week.

She added that the NCSC has dealt with "nationally significant incidents" along with hundreds of general cyber incidents that "affect the UK more widely every year".

While she didn't detail any specific instances of responding to ransomware incidents, Cameron warned that "these complex attacks have the potential to affect our societies and economies significantly", and implied that if it weren't for the work of NCSC incident responders, alongside their counterparts in the industry and international counterparts, the attacks could have had a major impact.

  • Study Reveals Traditional Data Security Tools Have a 60% Failure Rate Against Ransomware and Extortion

Titaniam, Inc., the data security platform, announced the ‘State of Data Exfiltration & Extortion Report.’ The survey revealed that while over 70% of organisations have an existing set of prevention, detection, and backup solutions, nearly 40% of organisations have been hit with ransomware attacks in the last year, and more than 70% have experienced one in the previous five years, proving existing solutions to be woefully inadequate in managing the risks and impacts from these attacks.

Data exfiltration during ransomware attacks is up 106% relative to where it was five years ago. We are seeing the emergence of a new trend where cyber criminals are no longer limiting themselves to just encrypting entire systems—they are making sure to steal data ahead of the encryption so that they can have additional leverage on the victim. The survey found that 65% of those who have experienced a ransomware attack have also experienced data theft or exfiltration due to the incident. Of those victims, 60% say the hackers used the data theft to extort them further, known as double extortion. Most of them, i.e., 59% of victims, paid the hackers, implying that they were not helped by their backup or data security tools to prevent this fate.

Data is being exposed for theft and extortion in other ways too. Nearly half (47%) uncovered publicly exposed data in their systems in the last 24 months. It was found that respondents have a mix of data security & protection (78%), prevention & detection (75%), and backup and recovery (73%) in their cyber security stacks. Still, exposure and extortion numbers imply a missing puzzle piece regarding attacks.

  • Patchable and Preventable Security Issues Lead Causes of Q1 Attacks

Attacks against companies spiked in Q1 2022 with patchable and preventable external vulnerabilities responsible for the bulk of attacks.

Eighty-two percent of attacks on organisations in Q1 2022 were caused by the external exposure of known vulnerabilities in the victim’s external-facing perimeter or attack surface. Those unpatched bugs overshadowed breach-related financial losses tied to human error, which accounted for 18 percent.

The numbers come from Tetra Defense and its quarterly report that sheds light on a notable uptick in cyber attacks against United States organisations between January and March 2022.

The report did not let employee security hygiene, or a lack thereof, off the hook. Tetra revealed that a lack of multi-factor authentication (MFA) mechanisms adopted by firms and compromised credentials are still major factors in attacks against organisations.

  • Three in Four Vulnerability Management Programs Ineffective

How at risk are organisations to unsecured vulnerabilities in their networks? NopSec, a threat and exposure management provider, gives us the answers in a new study of some 430 cyber security professionals.

Are security teams finding successful approaches to their vulnerability management, or are “open doors around their attack surface” leaving them susceptible to disaster in their organisation? The answer, as it turns out, is that some organisations are better at detection, response and remediation of their vulnerabilities.

Perhaps more importantly, others are not as locked down as they believe, according to the report. Keeping track of known vulnerabilities and responding quickly is one thing, but locating flaws they did not previously know existed is quite another.

Seventy percent of respondent say their vulnerability management program (VMP) is only somewhat effective or worse, blind spots and shadow IT remain top challenges, and vulnerabilities take too long to patch.

  • EMEA Continues to Be a Hotspot for Malware Threats

Ransomware detections in the first quarter of this year doubled the total volume reported for 2021, according to the latest quarterly Internet Security Report from the WatchGuard Threat Lab. Researchers also found that the Emotet botnet came back in a big way, the infamous Log4Shell vulnerability tripled its attack efforts and malicious cryptomining activity increased.

Although findings from the Threat Lab’s Q4 2021 report showed ransomware attacks trending down year over year, that all changed in Q1 2022 with a massive explosion in ransomware detections. While Q4 2021 saw the downfall of the infamous REvil cybergang, WatchGuard analysis suggests that this opened the door for the LAPSUS$ extortion group to emerge, which along with many new ransomware variants such as BlackCat – the first known ransomware written in the Rust programming language – could be contributing factors to an ever-increasing ransomware and cyber-extortion threat landscape.

The report also shows that EMEA continues to be a hotspot for malware threats. Overall regional detections of basic and evasive malware show WatchGuard Fireboxes in EMEA were hit harder than those in North, Central and South America (AMER) at 57% and 22%, respectively, followed by Asia-Pacific (APAC) at 21%.

  • A New, Remarkably Sophisticated Malware Is Attacking Home and Small Office Routers

An unusually advanced hacking group has spent almost two years infecting a wide range of routers in North America and Europe with malware that takes full control of connected devices running Windows, macOS, and Linux, researchers reported on June 28.

So far, researchers from Lumen Technologies' Black Lotus Labs say they've identified at least 80 targets infected by the stealthy malware, including routers made by Cisco, Netgear, Asus, and DrayTek. Dubbed ZuoRAT, the remote access Trojan is part of a broader hacking campaign that has existed since at least the fourth quarter of 2020 and continues to operate.

The discovery of custom-built malware written for the MIPS architecture and compiled for small-office and home-office routers is significant, particularly given its range of capabilities. Its ability to enumerate all devices connected to an infected router and collect the DNS lookups and network traffic they send and receive, and remain undetected, is the hallmark of a highly sophisticated threat actor.

"While compromising small office/home office (SOHO) routers as a vector to gain access to an adjacent LAN is not a novel technique, it has seldom been reported," Black Lotus Labs researchers wrote. "Similarly, reports of person-in-the-middle style attacks, such as DNS and HTTP hijacking, are even rarer and a mark of a complex and targeted operation. The use of these two techniques congruently demonstrated a high level of sophistication by a threat actor, indicating that this campaign was possibly performed by a state-sponsored organisation."

The campaign comprises at least four pieces of malware, three of them written from scratch by the threat actor. The first piece is the MIPS-based ZuoRAT, which closely resembles the Mirai internet-of-things malware that achieved record-breaking distributed denial-of-service attacks that crippled some Internet services for days. ZuoRAT often gets installed by exploiting unpatched vulnerabilities in SOHO devices.

  • What Are Shadow IDs, and How Are They Crucial in 2022?

Just before last Christmas, in a first-of-a-kind case, JPMorgan was fined $200M for employees using non-sanctioned applications for communicating about financial strategy. No mention of insider trading, naked shorting, or any malevolence. Just employees circumventing regulation using, well, Shadow IT. Not because they tried to obfuscate or hide anything, simply because it was a convenient tool that they preferred over any other sanctioned products (which JPMorgan certainly has quite a few of.)

Visibility into unknown and unsanctioned applications has been required by regulators and also recommended by the Center for Internet Security community for a long time. Yet it seems that new and better approaches are still in demand. Gartner has identified External Attack Surface Management, Digital Supply Chain Risk, and Identity Threat Detection as the top three trends to focus on in 2022, all of which are closely intertwined with Shadow IT.

"Shadow IDs," or in other words, unmanaged employee identities and accounts in third-party services, are often created using a simple email-and-password-based registration. Cloud access security broker (CASB) and corporate single-sign-on (SSO) solutions are limited to a few sanctioned applications, and are not widely adopted on most websites and services either. This means, that a large part of an organisation's external surface - as well as its user identities - may be completely invisible.

  • Zero-Days Aren't Going Away Anytime Soon, and What Leaders Need to Know

Few security exploits are the source of more sleepless nights for security professionals than zero-day attacks. Just recently, researchers discovered a new vulnerability enabling hackers to achieve remote code execution within Microsoft Office. Dubbing the evolving threat the Follina exploit, researchers say all versions of Office are at risk. And because the internal security teams have no time to prepare or patch their systems to defend against these software vulnerabilities, crafty threat actors can take advantage, taking their time after they've accessed an organisation's environment to observe and exfiltrate data while remaining completely unseen.

And though sophisticated threat actors and nations have exploited zero-days for nearly two decades, last year saw a historic rise in the number of vulnerabilities detected. Both Google and Mandiant tracked a record number of zero-days last year, with the caveat that more zero-days are being discovered because security companies are getting better at finding them — not necessarily because hackers are coming up with new vulnerabilities. Not all zero-days are created equal, though. Some require sophisticated and novel techniques, like the attack on SolarWinds, and others exploit simple vulnerabilities in commonly used programs like Windows. Thankfully, there's some basic cyber hygiene strategies that can keep your organisation sufficiently prepared to mitigate zero-day exploits.

https://www.darkreading.com/attacks-breaches/zero-days-aren-t-going-away-anytime-soon-and-what-leaders-need-to-know

  • Half of 2022's Zero-Days Are Variants of Previous Vulnerabilities

Google Project Zero has observed a total of 18 exploited zero-day vulnerabilities in the first half of 2022, at least half of which exist because previous bugs were not properly addressed.

According to Google Project Zero researcher Maddie Stone, nine of the in-the-wild zero-days seen so far this year could have been prevented had organisations applied more comprehensive patching.

“On top of that, four of the 2022 zero-days are variants of 2021 in-the-wild zero-days. Just 12 months from the original in-the-wild zero-day being patched, attackers came back with a variant of the original bug,” Stone says.

The most recent of these issues is the Follina vulnerability in the Windows platform. Tracked as CVE-2022-30190, it is a variant of an MSHTML zero-day tracked as CVE-2021-40444.

CVE-2022-21882 is another Windows vulnerability that is a variant of an in-the-wild zero-day that was improperly resolved last year, namely CVE-2021-1732.

An iOS IOMobileFrameBuffer bug (CVE-2022-22587) and a type confusion flaw in Chrome’s V8 engine (CVE-2022-1096) are two other zero-days that are variants of exploited security flaws found last year – CVE-2021-30983 and CVE-2021-30551, respectively.

Other 2022 zero-days that are variants of improperly addressed security defects are CVE-2022-1364 (Chrome), CVE-2022-22620 (WebKit), CVE-2021-39793 (Google Pixel), CVE-2022-26134 (Atlassian Confluence), and CVE-2022-26925 (Windows flaw called PetitPotam).

  • Human Error Remains the Top Security Issue

Human error remains the most effective vector for conducting network infiltrations and data breaches.

The SANS Institute security centre issued its annual security awareness report Wednesday, which was based on data from 1,000 infosec professionals and found that employees and their lack of security training remain common points of failure for data breaches and network attacks. The report also tracked the maturity level of respondents' security awareness programs and their effectiveness in reducing human risk.

"This year's report once again identifies what we have seen over the past three years: that the most mature security awareness programs are those that have the most people dedicated to managing and supporting it," the cyber security training and education organisation said.

"These larger teams are more effective at working with the security team to identify, track, and prioritise their top human risks, and at engaging, motivating, and training their workforce to manage those risks."

The SANS Institute study ranked maturity by five levels, from lowest to highest: nonexistent, compliance-focused, promoting awareness and behaviour change, long-term sustainment and culture change, and metrics framework. The report found that while approximately 400 respondents said their programs promote awareness and behaviour change - the highest such response for any maturity level - the number represented a 10% decrease from the previous year's report.

  • Carnival Cruises Torpedoed by US States, Agrees to Pay $6m After Wave of Cyber Attacks

Carnival Cruise Lines will cough up more than $6 million to end two separate lawsuits filed by 46 states in the US after sensitive, personal information on customers and employees was accessed in a string of cyber attacks.

A couple of years ago, as the coronavirus pandemic was taking hold, the Miami-based business revealed intruders had not only encrypted some of its data but also downloaded a collection of names and addresses; Social Security info, driver's license, and passport numbers; and health and payment information of thousands of people in almost every American state.

It all started to go wrong more than a year prior, as the cruise line became aware of suspicious activity in May 2019. This apparently wasn't disclosed until 10 months later, in March 2020.

Back in 2019, the security operations team spotted an internal email account sending spam to other addresses. It turned out miscreants had hijacked 124 employee Microsoft Office 365 email accounts, and were using them to send phishing emails to harvest more credentials. This, we're told, gave the intruders access to personal data on 180,000 Carnival employees and customers. It's likely the miscreants first broke in using phishing mails or brute-forcing passwords; either way, there was no multi-factor authentication.

Then in August 2020, the company said it was hit with the aforementioned ransomware, and copies of its files were siphoned. In January 2021, it was infected again with malware, and again sensitive information – specifically, customer passport numbers and dates of birth, and employee credit card numbers – were downloaded. And in March that year, a staffer's work email account was compromised again to send out a phishing email; more sensitive information was exposed.

  • Uber Ex-Security Chief Accused of Hacking Coverup Must Face Fraud Charges, Judge Rules

A federal judge on Tuesday said a former Uber Technologies Inc. security chief must face wire fraud charges over his alleged role in trying to cover up a 2016 hacking that exposed personal information of 57 million passengers and drivers.

The US Department of Justice had in December added the three charges against Joseph Sullivan to an earlier indictment, saying he arranged to pay money to two hackers in exchange for their silence, while trying to conceal the hacking from passengers, drivers and the US Federal Trade Commission.

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

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.

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.

Top Cyber Stories of the Last Week

‘Really Messy’: Why The Hack of Microsoft’s Email System Is Getting Worse, With Attacks Doubling Every Two Hours

The cyber security community sprang into action after Microsoft first announced a series of vulnerabilities that let hackers break into the company's Exchange email and calendar programs. China has used it to spy on a wide range of industries in the United States ranging from medical research to law firms to defence contractors, the company said. China has denied responsibility. In the past 24 hours, the team has observed "exploitation attempts on organizations doubling every two to three hours." The countries feeling the brunt of attack attempts are Turkey, the United States, and Italy, accounting for 19%, 18%, and 10% of all tracked exploit attempts, respectively.

Trickbot Malware Is Now Your Biggest Security Headache

Trickbot malware has risen to fill the gap left by the takedown of the Emotet botnet, with a higher number of criminals shifting towards it to distribute malware attacks. Emotet was the world's most prolific and dangerous malware botnet before it was disrupted by an international law enforcement operation in January this year.

Cyber Criminals Are Increasingly Targeting Browser Zero Days

As more and more of our work is done within our browsers, cyber criminals have begun to leverage web browser exploits to compromise endpoint systems, according to new research from Menlo Security. At the same time, enterprises around the world were forced to make an almost overnight transition to remote work last year and this surge in employees working from home along with the shift to cloud computing have resulted in a greatly increased attack surface.

https://www.techradar.com/news/cybercriminals-are-increasingly-targeting-browser-zero-days

More Than 1m Small Businesses ‘At Risk Of Collapse’ Due To Cyber Threats

The research, commissioned by Vodafone, also showed that 16 per cent of firms would likely be forced to lay off staff in the event of a hack. As a result, the report called on ministers to beef up the country’s corporate cyber defences, warning that a failure to do so could hamper the post-pandemic economic recovery. It urged the government to expand a dedicated business cyber security within the National Cyber Security Centre (NCSC), which is part of GCHQ, and introduce a five per cent VAT cut on cybersecurity products for small companies.

Number Of Ransomware Attacks Grew By More Than 150%

By the end of 2020, the ransomware market, fueled by the pandemic turbulence, had turned into the biggest cyber crime money artery. Based on the analysis of more than 500 attacks observed during Group-IB’s own incident response engagements and cyber threat intelligence activity, researchers estimate that the number of ransomware attacks grew by more than 150% in 2020.

Hackers Are Using Home Office Selfies To Steal Your Personal Data

The pandemic has been the source of plenty of memes and new internet trends, not least the remote working selfie, which involves people taking photos of their home office setup or video conferencing sessions. However, a new blog suggests cyber criminals are capitalizing on this new genre of selfie to steal a range of personal data that could be used to execute identity or financial fraud.
