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

Businesses Found to Neglect Cyber Security Until it is Too Late

Businesses only take cyber security seriously after falling victim to an attack, according to a report published by the UK's Department for Culture, Media and Sport (DCMS) this week.

For the research, the UK government surveyed IT professionals and end users in 10 UK organisations of varying sizes that have experienced cyber security breaches in the past three years. This analysed their existing level of security prior to a breach, the business impacts of the attack and how cyber security arrangements changed in the wake of the incident.

Nearly all respondents said their organisation took cyber security much more seriously after experiencing a breach, including reviewing existing practices and significantly increased investment in technology solutions.

While there was a consensus among participants that there is a greater need for vigilance and investment in cyber security, there was significant variation between organisations’ practices in this area. Medium and large organisations tended to have formal plans in place and budget allocated for further cyber security investment, but smaller businesses mostly did not due to resource constraints.

Cyber Tops Staff Retention as Biggest Business Risk

Cyber security concerns represent the most serious risk facing organisations, beating inflation, talent acquisition/retention and rising production costs, according to a new PwC study.

The PwC Pulse: Managing business risks in 2022 report was compiled from interviews with 722 US C-suite executives.

Two-fifths (40%) ranked cyber-attacks as a serious risk, rising to 51% of board members. PwC said boardrooms may be getting more attuned to cyber risk after new SEC proposals were published in March that would require directors to oversee cyber security risk and be more transparent about their cyber expertise.

In fact, executives appear to be getting more proactive with cyber security on a number of fronts.

Some 84% said they are taking action or monitoring closely policy areas related to cyber security, privacy and data protection. A further 79% said they’re revising or enhancing their cyber risk management approaches, and half (49%) pointed to increased investments in cyber security and privacy.

By way of comparison, 53% said they’re increasing investment in digital transformation and 52% in IT.

Cyber security is a strategic business enabler – technology is the central nervous system of many companies – and confirming its data is secure and protected can be brand defining.

There’s now heightened attention from a wider range of business leaders and corporate directors as they recognise that cyber security and data privacy should be part of not only a risk management strategy, but also a broader corporate strategy. C-suite and boards are actively taking steps to better understand the global threat landscape, confirm a foundational cyber security program is in place, and manage these risks to create opportunities.

Cyber Criminals Weaponising Ransomware Data for BEC Attacks

Cyber criminals and other threat actors are increasingly using data dumped from ransomware attacks in secondary business email compromise (BEC) attacks, according to new analysis by Accenture Cyber Threat Intelligence.

The ACTI team analysed data from the 20 most active ransomware leak sites, measured by number of featured victims, between July 2021 and July 2022. Of the 4,026 victims (corporate, non-governmental organisations, and governmental entities) uncovered on various ransomware groups’ dedicated leak sites, an estimated 91% incurred subsequent data disclosures, ACTI found.

Dedicated leak sites most commonly provide financial data, followed by employee and client personally identifiable information and communication documentation. The rise of double extortion attempts – where attack groups use ransomware to exfiltrate data and then publicise the data on dedicated leak sites – has made large amounts of sensitive corporate data available to any threat actor. The most valuable types of data most useful for conducting BEC attacks are financial, employee, and communication data, as well as operational documents. There is a significant overlap between the types of data most useful for conducting BEC attacks and the types of data most commonly posted on these ransomware leak sites, ACTI said.

The data is a “rich source for information for criminals who can easily weaponise it for secondary BEC attacks,” ACTI said. “The primary factor driving an increased threat of BEC and VEC attacks stemming from double-extortion leaks is the availability of [corporate and communication data].”

Callback Phishing Attacks See Massive 625% Growth Since Q1 2021

Hackers are increasingly moving towards hybrid forms of phishing attacks that combine email and voice social engineering calls as a way to breach corporate networks for ransomware and data extortion attacks.

According to Agari's Q2 2022 cyber-intelligence report, phishing volumes have only increased by 6% compared to Q1 2022. However, the use of 'hybrid vishing' is seeing a massive 625% growth.

Vishing, "voice phishing," involves some form of a phone call to perform social engineering on the victim. Its hybrid form, called "callback phishing," also includes an email before the call, typically presenting the victim with a fake subscription/invoice notice.

The recipient is advised to call on the provided phone number to resolve any issues with the charge, but instead of a real customer support agent, the call is answered by phishing actors.

The scammers then offer to resolve the presented problem by tricking the victim into disclosing sensitive information or installing remote desktop tools on their system. The threat actors then connect to the victim's device remotely to install further backdoors or spread to other machines.

These callback phishing attacks were first introduced by the 'BazarCall/BazaCall' campaigns that appeared in March 2021 to gain initial access to corporate networks for ransomware attacks.

The attacks work so well that multiple ransomware and extortion gangs, such as Quantum, Zeon, and Silent Ransom Group, have adopted the same technique today to gain initial network access through an unsuspecting employee.

"Hybrid Vishing attacks reached a six-quarter high in Q2, increasing 625% from Q1 2021. This threat type also contributed to 24.6% of the overall share of Response-Based threats," details the Agari report.

"While this is the second quarter hybrid vishing attacks have declined in share due to the overall increase of response-based threats, vishing volume has steadily increased in count over the course of the year."

Credential Phishing Attacks Skyrocketing, 265 Brands Impersonated in H1 2022

Abnormal Security released a report which explores the current email threat landscape and provides insight into the latest advanced email attack trends, including increases in business email compromise, the evolution of financial supply chain compromise, and the rise of brand impersonation in credential phishing attacks.

The research found a 48% increase in email attacks over the previous six months, and 68.5% of those attacks included a credential phishing link. In addition to posing as internal employees and executives, cyber criminals impersonated well-known brands in 15% of phishing emails, relying on the brands’ familiarity and reputation to convince employees to provide their login credentials. Most common among the 265 brands impersonated in these attacks were social networks and Microsoft products.

“The vast majority of cyber crime today is successful because it exploits the people behind the keyboard,” said Crane Hassold, director of threat intelligence at Abnormal Security.

“By compromising people rather than networks, it’s easier for attackers to circumvent conventional security measures. This is especially true with brand impersonation, where attackers use urgency and fear to encourage their targets to provide usernames and passwords.”

LinkedIn took the top spot for brand impersonation, but Outlook, OneDrive and Microsoft 365 appeared in 20% of all attacks. What makes these attacks particularly dangerous is that phishing emails are often the first step to compromising employee email accounts. Acquiring Microsoft credentials enables cyber criminals to access the full suite of connected products, allowing them to view sensitive data and use the account to send business email compromise attacks.

Are Cloud Environments Secure Enough for Today’s Threats?

Cyber security is a major problem right now. Not only is it the highest priority of any given business to keep their own data and their customers’ and clients’ data secure, but changes in the workplace have had a knock-on effect on cyber security. The concept of working from home has forced businesses all around the world to address old and new cyber security threats. People taking their laptops, and therefore their data, home to public networks that can be hacked or leaving access details like passwords scribbled on notebooks has meant that access to a business and therefore their customers’ data is a lot more accessible.

The saving grace was said to be the cloud. Beyond retraining cyber security in staff workforces, the practical solution was to move data into the cloud. But we’re now a few years from the point when the cloud really gained popularity. Is it still the answer to all our cyber security problems? Is there a chance of risk to using the cloud?

Cloud data breaches do happen and misconfiguration is a leading cause of them, mainly due to businesses inadequate cyber security strategies. This is due to several factors, such as the fundamental nature of the cloud designed to be easy for anyone to access, and businesses unable to completely see or control the cloud’s infrastructure and therefore relying on the cyber security controls that are provided by the cloud service provider (or CSP).

Unauthorised access is also a risk. The internet, which is a readily available public resource to most of the world, makes it easy for hackers to access data if they have the credentials to get past the cyber security set up by the individual business. This is where the ugliness of internal cloud breaches happens. If security is not configured well or credentials like passwords and secret questions are compromised, an attacker can easily access the cloud.

However, it’s not only through an employee that hackers access credentials. Phishing is a very common means of gaining information that would allow access to a customer or business data.

Plus, the simple nature of sharing data can easily backfire on a company. A lot of data access is granted with a link to someone external, which can then be forwarded, either sold or stolen, to an attacker to access the cloud’s data.

Most Q2 Attacks Targeted Old Microsoft Vulnerabilities

Attacks targeting a remote code execution vulnerability in Microsoft's MSHTML browser engine — which was patched last September — soared during the second quarter of this year, according to a Kaspersky analysis.

Researchers from Kaspersky counted at least 4,886 attacks targeting the flaw (CVE-2021-40444) last quarter, an eightfold increase over the first quarter of 2022. The security vendor attributed the continued adversary interest in the vulnerability to the ease with which it can be exploited.

Kaspersky said it has observed threat actors exploiting the flaw in attacks on organisations across multiple sectors including the energy and industrial sectors, research and development, IT companies, and financial and medical technology firms. In many of these attacks, the adversaries have used social engineering tricks to try and get victims to open specially crafted Office documents that would then download and execute a malicious script. The flaw was under active attack at the time Microsoft first disclosed it in September 2021.

Attacks targeting a remote code execution vulnerability in Microsoft's MSHTML browser engine — which was patched last September — soared during the second quarter of this year, according to a Kaspersky analysis. Researchers from Kaspersky counted at least 4,886 attacks targeting the flaw last quarter, an eightfold increase over the first quarter of 2022. The security vendor attributed the continued adversary interest in the vulnerability to the ease with which it can be exploited. According to Kaspersky, exploits for Windows vulnerabilities accounted for 82% of all exploits across all platforms during the second quarter of 2022. While attacks on the MSHTML vulnerability increased the most dramatically, it was by no means the most exploited flaw, which was a remote code execution vulnerability in Microsoft Office that was disclosed and patched four years ago that was attacked some 345,827 times last quarter.

Cyber Resiliency Isn't Just About Technology, It's About People

Cyber attacks are on the rise — but if we're being honest, that statement has been true for quite a while, given the acceleration of cyber incidents over the past several years. Recent research indicates that organisations experienced 50% more attack attempts per week on corporate networks in 2021 than they did in 2020, and tactics such as phishing are becoming increasingly popular as attackers refine their tried-and-true methods to more successfully entice unsuspecting targets.

It's no surprise, then, that cyber resiliency has been a hot topic in the cyber security world. But although cyber resiliency refers broadly to the ability of an organisation to anticipate, withstand, and recover from cyber security incidents, many experts make the mistake of applying the term specifically to technology. And while it's true that detection and remediation tools, backup systems, and other resources play an important role in cyber resiliency, organisations that focus exclusively on technology risk are overlooking an equally important element: people.

People are often thought of as the weak link in cyber security. It's easy to understand why. People fall for phishing scams. They use weak passwords and procrastinate on installing security updates. They misconfigure hardware and software, leave cloud assets unsecured, and send confidential files to the wrong recipient. There's a reason so much cyber security technology is moving toward automation: removing people from the equation is seen as one of the most obvious ways to improve security. To many security experts, that's just common sense.

Except — is it, really? It's true that people make mistakes — it's called "human error" for a reason, after all — but many of those mistakes come when employees aren't put in a position to succeed. Phishing is a great example. Most people are familiar with the concept of phishing, but many may not be aware of the nefarious techniques that today's attackers deploy. If employees have not been properly trained, they may not be aware that attackers often impersonate real people within the organisation, or that the CEO asking them to buy gift cards "for a company happy hour" probably isn't legit. Organisations that want to build strong cyber-resiliency cannot pretend that people don't exist. Instead, they need to prioritise the resiliency of their people just as highly as the resiliency of their technology.

Training the organisation to recognise the signs of common attack tactics, practice better password and cyber hygiene, and report signs of suspicious activity can help ease the burden on IT and security personnel by providing them better information in a more timely manner. It also avoids some of the pitfalls that create a drain on their time and resources. By ensuring that people at every level of the business are more resilient, today's organisations will discover that their overall cyber-resiliency will improve significantly.

The “Cyber Insurance Gap” Is Threatening Most Companies

A new study by BlackBerry and Corvus Insurance confirms a “cyber insurance gap” is growing, with a majority of businesses either uninsured or under insured against a rising tide of ransomware attacks and other cyber threats.

Only 19% of all businesses surveyed have ransomware coverage limits above the median ransomware demand amount ($600,000)
Among SMBs with fewer than 1,500 employees, only 14% have a coverage limit in excess of $600,000
37% of respondents with cyber insurance do not have any coverage for ransomware payment demands
43% of those with a policy are not covered for auxiliary costs such as court fees or employee downtime
60% say they would reconsider entering into a partnership or agreement with another business or supplier if the organisation did not have comprehensive cyber insurance
Endpoint detection and response (EDR) software is frequently a key component to obtaining a policy
34% of respondents have been previously denied cyber coverage by insurance providers due to not meeting EDR eligibility requirements

Easing the Cyber-Skills Crisis with Staff Augmentation

Filling cyber security roles can be costly, slow, and chancy. More firms are working with third-party service providers to quickly procure needed expertise.

There are many possible solutions to the cyber security skills shortage, but most of them take time. Cyber security education, career development tracks, training programs, employer-sponsored academies, and internships are great ways to build a talent pipeline and develop skill sets to meet organisational needs in years to come.

But sometimes the need to fill a gap in capability is more immediate.

An organisation in the entertainment industry recently found itself in such a position. Its primary cyber security staff member quit suddenly without notice, taking along critical institutional knowledge and leaving various projects incomplete. With its key defender gone, the organisation's environment was left vulnerable. In a scarce talent market, the organisation faced a long hiring process to find a replacement — too long to leave its digital estate unattended. It needed expertise, and quickly.

According to a 2021 ESG report, 57% of organisations have been impacted by the global cyber security skills crisis. Seventy-six percent say it's difficult to recruit and hire security professionals. The biggest effects of this shortage are increasing workloads, positions open for weeks or months, and high cyber security staff burnout and attrition.

In this climate, more companies are turning to third parties for cyber security staff reinforcement. According to a NewtonX study, 56% of organisations are now subcontracting up to a quarter of their cyber security staff. Sixty-nine percent of companies rely on third-party expertise to assist in mitigating the risk of ransomware — up from 58% in 2017 — per a study by Ponemon and CBI, a Converge Company.

One way that companies gain this additional support is via third-party staff augmentation and consulting services. Cyber security staff augmentation, or strategic staffing, entails trained external consultants acting as an extension of an organisation's security team in a residency. Engagements can be anywhere from a few weeks to a few years, and roles can range from analysts and engineers to architects, compliance specialists, and virtual CISOs.

Mailchimp Suffers Second Breach In 4 Months

Mailchimp suffered another data breach earlier this month, and this one cost it a client.

In a statement Friday, Mailchimp disclosed that a security incident involving phishing and social engineering tactics had targeted cryptocurrency and blockchain companies using the email marketing platform. It was the second Mailchimp breach to target cryptocurrency customers in a four-month span.

Though Mailchimp said it has suspended accounts where suspicious activity was detected while an investigation is ongoing, it did not reveal the source of the breach or scope of the attack.

More details were provided Sunday by one of the affected customers, DigitalOcean, which cut ties with Mailchimp on Aug. 9.

The cloud hosting provider observed suspicious activity beginning Aug. 8, when threat actors used its Mailchimp account for "a small number of attempted compromises" of DigitalOcean customer accounts -- specifically cryptocurrency platforms.

While it is not clear whether any DigitalOcean accounts were compromised, the company did confirm that some email addresses were exposed. More importantly, the statement attributed a potential source of the most recent Mailchimp breach.

Firm Told It Can't Claim Full Cyber Crime Insurance After Social Engineering Attack

A Minnesota computer store suing its cyber insurance provider has had its case dismissed, with the courts saying it was a clear instance of social engineering, a crime for which the insurer was only liable to cover a fraction of total losses.

SJ Computers alleged in a November lawsuit that Travelers Casualty and Surety Co. owed it far more than paid on a claim for nearly $600,000 in losses due to a successful business email compromise (BEC) attack.

According to its website, SJ Computers is a Microsoft Authorised Refurbisher, reselling Dell, HP, Lenovo and Acer products, as well as providing tech services including software installs and upgrades.

Travelers, which filed a motion to dismiss, said SJ's policy clearly delineated between computer fraud and social engineering fraud. The motion was granted with prejudice last Friday.

In the dismissal order, the US District Court for Minnesota found that the two policy agreements are mutually exclusive, as well as finding SJ's claim fell squarely into its social engineering fraud agreement with Travelers, which has a cap of $100,000.

When SJ filed its claim with Travelers, the court noted, it did so only under the social engineering fraud agreement. After realising the policy limit on computer fraud was 10 times higher, "SJ Computers then made a series of arguments – ranging from creative to desperate – to try to persuade Travelers that its loss was not the result of social-engineering-fraud (as SJ Computers itself had initially said) but instead the result of computer fraud," the district judge wrote in the order.
