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
Cyber Insurers Clamp Down on Clients' Self-Attestation of Security Controls
After one company suffered a breach that could have been headed off by the MFA it claimed to have, insurers are looking to confirm claimed cyber security measures.
A voided lawsuit from a cyber insurance carrier claiming its customer misled it on its insurance application could potentially pave the way to change how underwriters evaluate self-attestation claims on insurance applications.
The case — Travelers Property Casualty Company of America v. International Control Services Inc. (ICS) — hinged on ICS claiming it had multifactor authentication (MFA) in place when the electronics manufacturer applied for a policy. In May the company experienced a ransomware attack. Forensics investigators determined there was no MFA in place, so Travelers asserted it should not be liable for the claim. The case was filed in the US District Court for the Central District of Illinois on July 6 and at the end of August, the litigants agreed to void the contract, ending ICS's efforts to have its insurer cover its losses.
This case was unusual in that Travelers maintained the misrepresentation "materially affected the acceptance of the risk and/or the hazard assumed by Travelers" in the court filing. Taking a client to court is a departure from other similar cases where an insurance company simply denied the claim.
Sean O'Brien of Yale Law School notes that security should be proactive, stopping possible breaches before they occur rather than simply responding to each successful attack. The insurance industry is likely to become more and more pernickety as cyber security claims rise, defending their bottom line and avoiding reimbursement wherever possible. This has always been the role of insurance adjusters, of course, and their business is in many ways adversarial to your organisation's interests after the dust settles from a cyber attack.
That said, organisations should not expect a payout for poor cyber security policies and practices, he notes.
Survey Shows CISOs Losing Confidence in Ability to Stop Ransomware Attacks
Despite an 86% surge in budget resources to defend against ransomware, 90% of organisations were impacted by attacks last year, a survey reveals.
An annual survey of CISOs from Canada, the UK, and US reveals that security teams are starting to lose hope that they can defend against the next ransomware attack. The survey was conducted by SpyCloud, and it showed that although budgets to protect against cyber attacks have swelled by 86%, a full 90% of organisations surveyed said they had been impacted by a ransomware over the past year.
More organisations have implemented 'Plan B' measures this year, from opening cryptocurrency accounts to purchasing ransomware insurance. These findings suggest that organisations realise threats are slipping through their defences and a ransomware attack is inevitable.
The survey did show some bright spots on the cyber security front — nearly three-quarters of those organisations surveyed are using multifactor authentication (MFA), with an increase from 44% to 73% year-over-year. The report added that respondents said they are focused on stopping credential-stealing malware, particularly on unmanaged network devices.
MFA Fatigue: Hackers’ New Favourite Tactic in High-Profile Breaches
Hackers are more frequently using social engineering attacks to gain access to corporate credentials and breach large networks. One component of these attacks that is becoming more popular with the rise of multi-factor authentication is a technique called MFA Fatigue.
When breaching corporate networks, hackers commonly use stolen employee login credentials to access VPNs and the internal network. The reality is that obtaining corporate credentials is far from difficult for threat actors, who can use various methods, including phishing attacks, malware, leaked credentials from data breaches, or purchasing them on dark web marketplaces.
To counter this, enterprises have increasingly adopted multi-factor authentication to prevent users from logging into a network without first entering an additional form of verification. This additional information can be a one-time passcode, a prompt asking you to verify the login attempt, or the use of hardware security keys.
While threat actors can use numerous methods to bypass multi-factor authentication, most revolve around stealing cookies through malware or man-in-the-middle phishing attack frameworks. However, a social engineering technique called 'MFA Fatigue' is growing more popular with threat actors as it does not require malware or phishing infrastructure and has proven to be successful in attacks.
An MFA Fatigue attack is when a threat actor runs a script that attempts to log in with stolen credentials over and over, causing what feels like an endless stream of MFA push requests to be sent to the account's owner's mobile device. The goal is to keep this up, day and night, to break down the target's cyber security posture and inflict a sense of "fatigue" regarding these MFA prompts.
Credential Stuffing Accounts for One-third Of Global Login Attempts
Okta’s global State of Secure Identity Report has found that credential stuffing is the top threat against customer accounts, outpacing legitimate login traffic in some countries. The report presents trends, examples and observations unearthed from the billions of authentications on Okta’s Auth0 platform.
Credential stuffing is when attacks take advantage of the practice of password reuse. It begins with a stolen login or password pair, then threat actors use these credentials across other common sites, using automated tooling used to “stuff” credential pairs into login forms. When an account holder reuses the same (or similar) passwords on multiple sites, it creates a domino effect in which a single credential pair can be used to breach multiple applications.
Across all industries globally, Okta found there were almost 10 billion credential stuffing attempts in the first 90 days of 2022, which amounts to 34% of authentication traffic.
Ransomware Operators Might Be Dropping File Encryption in Favour of Corrupting Files
Corrupting files is faster, cheaper, and less likely to be stopped by endpoint protection tools than encrypting them.
A recent attack that involved a threat actor believed to be an affiliate of the BlackCat/ALPHV ransomware-as-a-service (RaaS) operation was found to use a data exfiltration tool dubbed Exmatter. Exmatter is a tool that allows attackers to scan the victim computer's drives for files with certain extensions and then upload them to an attacker-controlled server in a unique directory created for every victim. The tool supports several exfiltration methods including FTP, SFTP, and webDAV.
The way the Eraser function works is that it loads two random files from the list into memory and then copies a random chunk from the second file to the beginning of the first file overwriting its original contents. This doesn't technically erase the file but rather corrupts it. The researchers believe this feature is still being developed because the command that calls the Eraser function is not yet fully implemented and the function’s code still has some inefficiencies. Since the selected data chunk is random, it can sometimes be very small, which makes some files more recoverable than others.
Why destroy files by overwriting them with random data instead of deploying ransomware to encrypt them? At a first glance these seem like similar file manipulation operations. Encrypting a file involves overwriting it, one block at a time, with random-looking data (the ciphertext). However, there are ways to detect these encryption operations when done in great succession and many endpoint security programs can now detect when a process exhibits this behaviour and can stop it. Meanwhile, the kind of file overwriting that Exmatter does is much more subtle.
The act of using legitimate file data from the victim machine to corrupt other files may be a technique to avoid heuristic-based detection for ransomware and wipers, as copying file data from one file to another is much more plausibly benign functionality compared to sequentially overwriting files with random data or encrypting them.
Another reason is that encrypting files is a more intensive task that takes a longer time. It's also much harder and costly to implement file encryption programs, which ransomware essentially are, without bugs or flaws that researchers could exploit to reverse the encryption. There have been many cases over the years where researchers found weaknesses in ransomware encryption implementations and were able to release decryptors. This has happened to BlackMatter, the Ransomwware-as-a-Service (RaaS) operation with which the Exmatter tool has been originally associated.
With data exfiltration now the norm among threat actors, developing stable, secure, and fast ransomware to encrypt files is a redundant and costly endeavour compared to corrupting files and using the exfiltrated copies as the means of data recovery.
It remains to be seen if this is the start of a trend where ransomware affiliates switch to data destruction instead of encryption, ensuring the only copy is in their possession, or if it's just an isolated incident where BlackMatter/BlackCat affiliates want to avoid mistakes of the past. However, data theft and extortion attacks that involve destruction are not new and have been widespread in the cloud database space. Attackers have hit unprotected S3 buckets, MongoDB databases, Redis instances, and ElasticSearch indexes for years, deleting their contents and leaving behind ransom notes so it wouldn't be a surprise to see this move to on-premises systems as well.
Revolut Hack Exposes Data Of 50,000 Users, Fuels New Phishing Wave
Revolut has suffered a cyber attack that gave an unauthorised third party access to personal information of tens of thousands of clients. The incident occurred over a week ago, on Sunday night, and has been described as "highly targeted."
Founded in 2015, Revolut is a financial technology company that has seen a rapid growth, now offering banking, money management, and investment services to customers all over the world. In a statement a company spokesperson said that an unauthorised party had access "for a short period of time" to details of only a 0.16% of its customers.
"We immediately identified and isolated the attack to effectively limit its impact and have contacted those customers affected. Customers who have not received an email have not been impacted" , Revolut said.
According to the breach disclosure to the State Data Protection Inspectorate in Lithuania, where Revolut has a banking license, 50,150 customers have been impacted. Based on the information from Revolut, the agency said that the number of affected customers in the European Economic Area is 20,687, and just 379 Lithuanian citizens are potentially impacted by this incident.
Details on how the threat actor gained access to the database have not been disclosed but it appears that the attacker relied on social engineering. The Lithuanian data protection agency notes that the likely exposed information includes:
Email addresses
Full names
Postal addresses
Phone numbers
Limited payment card data
Account data
However, in a message to an affected customer, Revolut says that the type of compromised personal data varies for different customers. Card details, PINs, or passwords were not accessed.
Researchers Say Insider Threats Play a Larger Role In Security Incidents
Insider threats are becoming an increasingly common part of the attack chain, with malicious insiders and unwitting assets playing critical roles in incidents over the past year, according to Cisco Talos research.
In a blog post, Cisco Talos researchers said organisations can mitigate these types of risks via education, user-access control, and ensuring proper processes and procedures are in place when and if employees leave the organisation.
There are a variety of reasons a user may choose to become a malicious insider, and unfortunately many of them are occurring today. The most obvious being financial distress, where a user has a lot of debt and selling the ability to infect their employer can be a tempting avenue. There have been examples of users trying to sell access into employer networks for more than a decade, having spotted them on dark web forums. The current climate, with the economy tilting toward recession, is ripe for this type of abuse.
The cyber crime underground remains a hot spot for insider threat recruitment efforts because of the relative anonymity, accessibility, and low barrier of entry it affords. Malicious actors use forums and instant messaging platforms to advertise their insider services or, vice versa, to recruit accomplices for specific schemes that require insider access or knowledge.
By far, the most popular motivation for insider threats is financial gain. There are plenty of examples of financially-motivated threat actors seeking employees at companies to provide data and access to sell in the underground or leverage against the organisation or its customers. There have also been instances where individuals turn to underground forums and instant messaging platforms claiming to be employees at notable organisations to sell company information.
SMBs vs. Large Enterprises: Not All Compromises Are Created Equal
Attackers view smaller organisations as having fewer security protocols in place, therefore requiring less effort to compromise. Lumu has found that compromise is significantly different for small businesses than for medium-sized and large enterprises.
There is no silver bullet for organisations to protect themselves from compromise, but there are critical steps to take to understand your potential exposure and make sure that your cyber security protocols are aligned accordingly.
Compromise often stay undetected for long periods of time – 201 days on average with compromise detection and containment taking approximately 271 days. It’s critical for smaller businesses to know they are more susceptible and to get ahead of the curve with safeguards.
Results from the Lumu Ransomware Assessment show a few reasons why attacks continue to stay undetected for such long periods of time:
· 58% of organisations aren’t monitoring roaming devices, which is concerning with a workforce that has embraced remote working
· 72% of organisations either don’t or only partially monitor the use of network resources and traffic, which is problematic given that most compromises tend to originate from within the network
· Crypto-mining doesn’t appear to be a concern for the majority of organisations as 76% either do not know or only partially know how to identify it; however, this is a commonly used technique for cyber criminals
Additionally, threat data unveils attack techniques used and how they vary based on the size of the organisation.
Small businesses are primarily targeted by malware attacks (60%) and are also at greater risk of Malware, Command and Control, and Crypto-Mining. Medium-sized businesses and large enterprises don’t see as much malware and are more susceptible to Domain Generated Algorithms (DGA). This type of attack allows adversaries to dynamically identify a destination domain for command and control traffic rather than relying on a list of static IP addresses or domains.

Cyber Attack Costs for Businesses up by 80%
In seven out of eight countries, cyber attacks are now seen as the biggest risk to business — outranking COVID-19, economic turmoil, skills shortages, and other issues. The "Hiscox Cyber Readiness Report 2022," which assesses how prepared businesses are to fight back against cyber incidents and breaches, polled more than 5,000 corporate cyber security professionals in the US, UK, Belgium, France, Germany, Ireland, Spain, and the Netherlands. These experts had some enlightening things to say.
According to the report, IT pros are more worried about cyber attacks (46%) than the pandemic (43%) or skills shortages (38%). And the data prove it. The survey indicates that in the past 12 months, US businesses weathered a 7% increase in cyber attacks. Approximately half of all US businesses (47%) suffered an attack in the past year.
Remote work has caused many smaller organisations to use cloud solutions instead of utilizing in-house IT services. However, with more cloud applications and APIs in use, the attack surface has broadened, too, making these organisations more vulnerable to cyber crime.
Although the proportion of staff working remotely almost halved in the past year — from 62% of the workforce in 2021 to 39% in 2022 — overall IT expenditures doubled, from $11.5 million in 2021 to $24.2 million this year. "Despite 61% of survey respondents now being back in the office, businesses are still experiencing a hangover from the pandemic," Hiscox said in a statement. "Remote working provided a year-long Christmas for cyber criminals, and we can see the results of their cyber-feast in the increased frequency and cost of attacks. As we move into a new era of hybrid working, we all have an increased responsibility to continue learning, and managing our own cyber security."
It may come as no surprise that as more organisations evolve and scale their digital business models, the median cost of an attack has surged — from $10,000 last year to $18,000 in 2022. The US is bearing the brunt of generally higher cyber attack costs, with 40% of attack victims incurring costs of $25,000 or higher. The most common vulnerability — i.e., the entry point for cyber criminals — was a cloud-based corporate server.
However, in terms of attack costs, the report reveals major regional disparities. While one organisation in the UK suffered total attack costs of $6.7 million, the hardest-hit firms in Germany, Ireland, and the Netherlands paid out more than $5 million. In turn, Belgium, France, Germany, and Spain all experienced stable or lower median costs.

Morgan Stanley Fined $35m By SEC For Data Security Lapse, Sold Devices Full of Customer PII
American financial services giant Morgan Stanley agreed to pay the Securities and Exchange Commission (SEC) a $35m penalty on Tuesday over data security lapses.
According to the SEC's complaint, the firm would have allowed roughly 1000 unencrypted hard drives (HDDs) and about 8000 backup tapes from decommissioned data centres to be resold on auction sites without first being wiped.
The improper disposal of the devices reportedly started in 2016 and per the SEC complaint, was part of an "extensive failure" that exposed 15 million customers' data.
In fact, instead of destroying the hard drives or employing an internal IT team to erase them, Morgan Stanley would have contracted an unnamed third–party moving company with allegedly no experience in decommissioning storage media to take care of the hardware.
The moving company initially subcontracted an IT firm to wipe the drives, but their business relationship went sour, so the mover started selling the storage devices to another firm that auctioned them online without erasing them.
"This is an astonishing security mistake by one of the world's most prestigious banks, who would be expected to have well–established procedures in system life cycle management," Jordan Schroeder, managing CISO at Barrier Networks, told Infosecurity Magazine.
"Not only does the situation mean that the bank put customer data at risk, but it also demonstrates the organisation was not following an expected policy which explained the secure disposing of IT equipment."

Eyeglass Reflections Can Leak Information During Video Calls
A group of academic researchers have devised a method of reconstructing text exposed via participants’ eyeglasses and other reflective objects during video conferences.
Zoom and other video conferencing tools, which have been widely adopted over the past couple of years as a result of the Covid-19 pandemic, may be used by attackers to leak information unintentionally reflected in objects such as eyeglasses, the researchers say.
Using mathematical modelling and human subjects experiments, this research explores the extent to which emerging webcams might leak recognizable textual and graphical information gleaming from eyeglass reflections captured by webcams.
Dubbed ‘webcam peeking attack’, a threat model devised by academics shows that it is possible to obtain an accuracy of over 75% when reconstructing and recognizing text with heights as small as 10 mm, captured by a 720p webcam.
According to the academics, attackers can also rely on webcam peeking to identify the websites that the victims are using. Moreover, they believe that 4k webcams will allow attackers to easily reconstruct most header texts on popular websites.
To mitigate the risk posed by webcam peeking attacks, the researchers propose both near- and long-term mitigations, including the use of software that can blur the eyeglass areas of the video stream. Some video conferencing solutions already offer blurring capabilities, albeit not fine-tuned.

Uber Says It Was Likely Hacked by Teenage Hacker Gang LAPSUS$
Uber has published additional information about how it was hacked, claiming that it was targeted by LAPSUS$, a cyber criminal gang with a hefty track record that is thought to be composed largely of teenagers.
Last week, someone broke into Uber’s network and used the access to cause all sorts of chaos. The culprit, who claims to be 18 years old, managed to spam company staff with vulgar Slack messages, post a picture of a penis on the company’s internal websites, and leak images of Uber’s internal environment to the web. Now, the ride-share giant has released a statement providing details on its ordeal.
In its update, the company has clarified how it was hacked, largely confirming an account made by the hacker themself. Uber says that the hacker exploited the login credentials of a company contractor to initially gain access to the network. The hacker may have originally bought access to those credentials via the dark web, Uber says. The hacker then used them to make multiple login attempts to the contractor’s account. The login attempts prompted a slew of multi-factor authentication requests for the contractor, who ultimately authenticated one of them. The hacker has previously claimed that it conducted a social engineering scheme to convince the contractor to authenticate the login attempt.
Security experts have called this an “MFA fatigue” attack. This increasingly common intrusion tactic seeks to overwhelm a victim with authentication push requests until they validate the hacker’s illegitimate login attempt.
Most interestingly, Uber has also claimed that whoever was behind this hacking episode is affiliated with the cyber crime gang “LAPSUS$.” It’s not totally clear how Uber knows that.

Top Cyber Stories of the Last Week
Covid Impact Heightens Risk Of Cyber Security Breaches
CYBER SECURITY breaches are the biggest staff-related risk as Covid-19 and recruitment difficulties continue to impact workplaces, according to a survey of Channel Island employers.
Seven out of ten senior HR professionals and business leaders saw a cyber security breach as the greatest staff-related risk for a regulated financial services business – way ahead of employees leaving (16%) and employees working from home (10%). Some 57% of employers said Covid-19 had changed their policies, procedures and systems ‘moderately’, with 29.5% reporting ‘significant’ changes, according to the research undertaken at a virtual employment conference organised by Walkers last month.
https://guernseypress.com/news/2021/11/12/covid-impact-heightens-risk-of-cyber-security-breaches/
81% of Organisations Experienced Increased Cyber Threats During COVID-19
More than four in five (81%) organisations experienced increased cyber-threats during the COVD-19 pandemic, according to a new study by McAfee and FireEye.
The global survey of 1451 IT and line of business decision-makers found that close to half (43%) have suffered from downtime due to a cyber concern. This resulted in costs of $100,000 for some organisations.
Despite the increased threat landscape and the fact that over half (57%) of organisations saw a rise in online/web activity, 24% of respondents revealed they have had their technology and security budgets reduced over this period.

Phishing Attacks Grow 31.5% Over 2020, Social Media Attacks Continue To Climb
Phishing remains the dominant attack vector for bad actors, growing 31.5 percent over 2020, according to a PhishLabs report. Notably, attacks in September 2021 were more than twice as high as the previous year.
https://www.helpnetsecurity.com/2021/11/11/phishing-attacks-grow-2020/
Threat from Organised Cyber Crime Syndicates Is Rising
Europol reports that criminal groups are undermining the EU’s economy and its society, offering everything from murder-for-hire to kidnapping, torture and mutilation.
From encrypting communications to fencing ill-gotten gains on underground sites, organised crime is cashing in on the digital revolution.
The latest organised crime threat assessment from Europol issues a dire warning about the corrosive effect the rising influence of criminal syndicates is having on both the economy and society of the European Union. And it’s all happening online.

Ransomware Gangs Are Using These 'Ruthless' Tactics As They Aim For Bigger Payouts
More sophisticated ransomware attacks are on the way as cyber criminals tailor campaigns to raise the chances of a ransom payment.
Ransomware attacks are becoming more sophisticated as cyber criminals continue to develop new techniques to make campaigns more effective and increase their chances of successfully demanding a ransom payment.
According to the European law enforcement agency Europol there was a 300% increase in the number of ransom payments between 2019 and 2020 alone – and that doesn't account for 2021 being another bumper year for cyber criminals launching ransomware attacks, as they've taken advantage of security vulnerabilities presented by the rise in remote working.
Europol's Internet Organised Crime Threat Assessment (IOCT) shows that while cybercrime, including malware and DDoS attacks, continues to evolve, it's ransomware attacks that have been a significant amount of disruption over the course of the past year.
Firms Will Struggle to Secure Extended Attack Surface in 2022
Companies are relying more heavily on third parties, remote employees, and partners, expanding their attack surface area beyond traditional boundaries.
In 2022, much of cybersecurity will boil down to managing the security of relationships, as companies adapt to the post-pandemic remote workforce and the increased use of third-party providers, a panel of analysts stated at the Forrester Research Security & Risk 2021 Conference.
Among five predictions for the coming year, the analysts argued that companies' attempts to manage remote employees would stray into intrusive territory, causing workers to push back and hampering security-focused monitoring, such as that for insider threats. Other predictions maintain that 60% of security incidents in the next year will come from issues with third parties, while the cybersecurity workforce will suffer from burnout and join what's been called the "Great Resignation," the recent trend of workers leaving the workforce.

Millions Of Home Wi-Fi Routers Threatened By Malware — What To Do
Netgear, Linksys, D-Link routers among those targeted
There's a nasty new piece of malware out there targeting Wi-Fi routers, and you'll want to make sure yours is fully updated so it doesn't get infected.
The AT&T researchers who discovered the malware are calling it BotenaGo, and it's apparently different from the Mirai botnet malware that's been attacking routers since 2016. BotenaGo packs in exploits for 33 different known vulnerabilities in 12 different router brands, including D-Link, Linksys, Netgear, Tenda, Totolink, Zyxel and ZTE. A full list is on the AT&T Cybersecurity blog post.
To avoid infection, ensure you update your router with the latest firmware.

80% Of Organisations Experienced Employees Misusing And Abusing Access To Business Apps
Organisations continue to operate with limited visibility into user activity and sessions associated with web applications, despite the ever-present risk of insider threats and credential theft, a CyberArk research reveals.
While the adoption of web applications has brought flexibility and increased productivity, organisations often lag in implementing the security controls necessary to mitigate risk of human error or malicious intent.

Gen Z Is Behaving Recklessly Online - And Will Live To Regret It
Handing out personal information could be a slippery slope
Members of Generation Z, the cohort of people born in the first decade of the 21st century, care about digital privacy, but their desire for online fame and popularity is greater, a new study from ExpressVPN suggests.
The VPN provider surveyed 1,500 young adults from the US to evaluate their online habits and attitudes towards social media, and identified a troubling pattern that could have dire consequences.
The survey found that Generation Z isn’t trusting of the social media platforms they frequent, expressing concern that platforms may be using their images for facial recognition (67%) and wariness about oversharing personal information (66%).
