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

Coalition Finds More Than Half of Cyber Insurance Claims Originate in the Email Inbox

The 2024 Cyber Claims Report by insurer Coalition reveals critical vulnerabilities and trends affecting cyber insurance policyholders. Notably, over half of the claims in 2023 stemmed from funds transfer fraud (FTF) and business email compromise (BEC), underlining the critical role of email security in cyber risk management. The report also indicated heightened risks associated with boundary devices like firewalls and VPNs, particularly if they are exposed online and have known vulnerabilities. Additionally, the overall claims frequency and severity rose by 13% and 10% respectively, pushing the average loss to $100,000. These insights emphasise the necessity of proactive cyber security measures and the valuable role of cyber insurance in mitigating financial losses from cyber incidents.

Unmasking the True Cost of Cyber Attacks: Beyond Ransom and Recovery

The global cost of cyber crime is expected to soar to $10.5 trillion annually by 2025, a steep rise from $3 trillion in 2015, underscoring a significant improvement in the methods of cyber criminals, according to Cybersecurity Ventures. Beyond direct financial losses like ransomware payments, the hidden costs of cyber attacks for businesses include severe operational disruptions, lost revenue, damaged reputations, strained customer relationships, and regulatory fines. These incidents, further exacerbated by increased insurance premiums, collectively contribute to substantial long-term financial burdens. The report indicates that 88% of data breaches are attributable to human error, underscoring the importance of comprehensive employee training alongside technological defences. To combat these evolving cyber threats effectively, organisations must adopt a multi-pronged strategy that includes advanced security technologies, regular system updates, employee education, and comprehensive security audits.

According to another report from SiliconAngle, cyber insurance claims increased 13% year-over-year in 2023, with the 10% rise in overall claims severity attributed to mounting ransomware attack claims.

Why Cyber Security Should Be Driving Your Enterprise Risk Management Strategy

Cyber security has transformed from a secondary concern into the cornerstone of corporate risk management. The historical view of cyber security as merely a component of broader risk strategies is outdated; it now demands a central role in safeguarding against operational, financial, and reputational threats. Many businesses, recognising the vital role of technology in all operations, have begun elevating the position of Chief Information Security Officer (CISO) to integrate cyber security into their overall enterprise risk frameworks. This shift not only enhances visibility and strategic alignment at the highest organisational levels but also fosters more robust defences against cyber threats. As such, adopting a cyber security-centric approach is crucial for compliance and long-term resilience in the face of growing digital threats.

Ransomware Double-Dip: Re-Victimisation in Cyber Extortion

A recent cyber security study reveals a troubling trend of re-victimisation among organisations hit by cyber extortion or ransomware attacks. Analysis of over 11,000 affected organisations shows recurring victimisation due to repeated attacks, data reuse among criminal affiliates, or cross-affiliate data sharing. Notably, cyber extortion incidents have surged by 51% year-on-year. Additionally, a separate study reports payments exceeding $1 billion and a 20% increase in ransomware attack victims since early 2023. These findings underscore the increasing sophistication and persistence of cyber criminals. Despite law enforcement efforts, adaptable cyber crime groups swiftly resume operations, complicating effective threat mitigation. Organisations must enhance their cyber security measures to avoid becoming repeated targets.

AI is a Major Threat and Many Financial Organisations Are Not Doing Enough

Artificial intelligence (AI) is a major concern for organisations, especially for the financial services sector due to the information they hold. Recent reports have found that AI has driven phishing up by 60% and AI tools have been linked to data exposure in 1 in 5 UK organisations. But it is not just attackers utilising AI: a separate report found that 20% of employees have exposed data via AI.

Currently, many financial organisations are not doing enough to secure themselves to fight AI. In a recent survey, 69% of fraud-management decision makers, AML professionals, and risk and compliance leaders reported that criminals are more advanced at using AI for financial crime than firms are in defending against it.

6 out of 10 Businesses Struggle to Manage Cyber Risk

A report has found that 6 in 10 businesses are struggling to manage their cyber risk and just 43% have confidence in their ability to address cyber risk. Further, 35% of total respondents worry that senior management does not see cyber attacks as a significant risk; the same percentage also reported a struggle in hiring skilled professionals. When it came to implementing their security policy, half of respondents found difficulty, and when it came to securing the supply chain, a third reported worries.

Given the inevitability of a cyber attack, organisations need to prepare themselves. Those that struggle to manage their cyber risk and/or hire skilled professions will benefit from outsourcing to skilled, reputable cyber security organisations who can guide them through the process.

'Junk Gun' Ransomware: New Low-Cost Cyber Threat Targets SMBs

Sophos’ research reveals a concerning trend: ‘junk gun’ ransomware variants are now traded on the dark web. Rather than going the traditional route of selling or buying ransomware to or as an affiliate, attackers have now begun creating and selling unsophisticated ransomware variants for a one-time cost. Priced at a median of $375, they attract lower-skilled attackers, especially those targeting small and medium-sized businesses (SMBs). As major ransomware players fade, these variants pose significant threats, accounting for over 75% of cyber incidents affecting SMBs in 2023.

Penetration Testing Infrequency Leaves Security Gaps

Many organisations are struggling to maintain the balance between penetration testing and IT changes within the organisation, leaving security gaps according to a recent report. The report found that 73% of organisations reported changes to their IT environments at least quarterly, however only 40% performed penetration testing at the same frequency.

The issue arises where there is a significant duration during which changes have been implemented without undergoing assessment, leaving organisations open to risk for extended periods of time. Consider the situation in which an organisation moves their infrastructure from on-premise to the cloud: they now have a different IT environment, and with that, new risks.

Black Arrow always recommends that a robust penetration test should be conducted whenever changes to internet facing infrastructure have been made, and at least annually.

Bank Prohibited from Opening New Accounts After Regulators Lose Patience with Poor Cyber Security Governance

A bank in India has been banned from signing up new customers, and instructed to focus on improving its cyber security after “serious deficiencies and non-compliances” were found within their IT environment. The compliances provided by the bank were described as “inadequate, incorrect or not sustained”. The bank is now subject to an external audit, which if passed, will consider the lifting of the restrictions placed upon them.

The Psychological Impact of Phishing Attacks on Your Employees

Phishing remains one of the most prevalent attack vectors for bad actors, and its psychological impact on employees can be severe, with many employees facing a loss in confidence and job satisfaction as well as an increase in anxiety. In a study by Egress, it was found that 74% of employees were disciplined, dismissed or left voluntarily after suffering a phishing incident, which can cause hesitation when it comes to reporting phishing.

Phishing incidents and simulations where employees have clicked should be seen as an opportunity to learn, not to blame, and to understand why a phish was successful and what can be done in future to prevent it. Organisations should perform security education and awareness training to help employees lessen their chance of falling victim, as well as knowing the reporting procedures.

Source: [Beta News]

Where Hackers Find Your Weak Spots

A recent analysis highlights social engineering as a primary vector for cyber attacks, emphasising its reliance on meticulously gathered intelligence to exploit organisational vulnerabilities. Attackers leverage various intelligence sources; Open Source Intelligence (OSINT) for public data, Social Media Intelligence (SOCMINT) for social media insights, Advertising Intelligence (ADINT) from advertising data, Dark Web Intelligence (DARKINT) from the DarkWeb, and the emerging AI Intelligence (AI-INT) using artificial intelligence. These methods equip cyber criminals with detailed knowledge about potential victims, enabling targeted and effective attacks. The report underscores the critical importance of robust information management and employee training to mitigate such threats, specifically advocating for regular training, AI-use policies, and proactive intelligence gathering by organisations to protect against the substantial risks posed by social engineering.

The Role of Threat Intelligence in Financial Data Protection

The financial industry’s reliance on digital processes has made it vulnerable to cyber attacks. Criminals target sensitive customer data, leading to financial losses, regulatory fines, and reputational damage. To combat these threats such as phishing, malware, ransomware, and social engineering, financial institutions must prioritise robust cyber security measures. One effective approach is threat intelligence, which involves ingesting reliable threat data, customised to your sector and the technology you have in place, and dark web monitoring.

Government Cannot Protect Business and Services from Cyber Attack, Decision Makers Say

According to a recent report, 66% of surveyed IT leaders expressed a lack of confidence in their government’s ability to defend people and enterprises from cyber attacks, especially those from nation state actors. This scepticism arises from the growing complexity of threats and the rapid evolution of cyber warfare. While governments play a critical role in national security, their agility in adapting to the ever-changing digital landscape leaves organisations finding themselves increasingly responsible for their own protection.

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 Attacks Reach Two-Year High Amid Ransomware Resurgence as Financial Service Firms Lose $32 Billion in 5 Years

The average weekly volume of cyber attacks reached a two-year high in the second quarter of 2023 amid a spike in activity among ransomware groups according to Check Point Research, with healthcare in particular facing a significant year-on-year increase. The impact of ransomware hits every organisation, with separate research finding global financial services organisations having lost over $32bn in downtime since 2018 due to ransomware breaches.

A recent report found that the ransomware gangs LockBit and Cl0p alone accounted for nearly 40% of all recorded ransomware attacks across June 2023. The impact from Cl0p’s MOVEit attack alone has been felt by over 400 organisations since May 2023. One of the key takeaways from the MOVEit attack is that no matter the sector, any organisation can be a victim and as such it is essential to have effective controls in place, incorporating defence-in-depth. It’s worth considering how many organisations are still running vulnerable instances of MOVEit, or have someone in their supply chain who is.

https://www.itpro.com/security/ransomware/weekly-cyber-attacks-reach-two-year-high-amid-ransomware-resurgence

  • MOVEit Body Count Closes in on 400 Organisations, 20M+ Individuals

The number of victims and the costs tied to the MOVEit file transfer hack continues to climb as the fallout from the massive supply chain attack enters week seven. In late May 2023, Russian ransomware gang Cl0p exploited a security hole in Progress Software's MOVEit product suite to steal documents from vulnerable networks. As of last week, the number of affected organisations was closing in on 400 and individual victims exceed 20 million.

The attack highlights the need for organisations to have policies and procedures in place for third parties, and to be aware of the data which a third party supplier has on them. It will be the organisation who will need to let their customers know in the event of a breach.

https://www.theregister.com/2023/07/20/moveit_victim_count/

  • IT Worker Jailed for Impersonating Ransomware Gang to Extort Employer

28-year-old Ashley Liles, a former IT employee, has been sentenced to over three years in prison for attempting to blackmail his employer during a ransomware attack. Liles, an IT security analyst at an Oxford-based company in the UK, exploited his position to intercept a ransomware payment following an attack suffered by his employer. To deceive the company, he impersonated the ransomware gang extorting them. He tried to redirect the ransomware payments by switching the cyber criminals' cryptocurrency wallet to one under his control. He also accessed a board member's private emails over 300 times.

Insider threat is a risk that organisations need to be aware of and, although it was malicious in this case, it can also come from employee negligence. Organisations looking to achieve a strong level of cyber resilience should incorporate insider risk into their training and controls.

  • Stabilising the Cyber Security Landscape: The CISO Exodus and the Rise of vCISOs

In today's evolving digital landscape, the role of a chief information security officer (CISO) is critical. These professionals defend against the rising tide of daily cyber threats. Yet many CISOs are leaving or considering leaving their jobs; this trend seems to reflect the intense pressure CISOs endure. They face a constant stream of complex cyber threats, manage compliance issues and struggle with a talent deficit in cyber security. Paired with high expectations, many reconsider their roles which can lead to a leadership gap.

A virtual CISO (vCISO) is an outsourced security practitioner who offers their expertise to businesses on a part-time or contractual basis. These professionals provide many of the same services as a traditional CISO, such as developing and implementing security strategies, ensuring compliance with regulations, training staff and managing a company's cyber security posture. vCISOs, such as from Black Arrow, are often part of a larger team and can bring a wide range of experiences and skills. They are exposed to diverse security landscapes across industries, and can provide a fresh perspective and innovative solutions to your security challenges. The vCISO model may not replace the need for a full-time CISO in all cases, but it can certainly add a flexible and cost-effective tool to the arsenal of businesses looking to bolster their cyber security posture.

  • Risk is Driving Medium-Sized Business Decisions

Small and medium sized businesses (SMBs) have long lacked the tools, expertise, staff and budget to make major cyber security investments. However, as threats become more mainstream and more advanced, the focus is shifting, so SMBs need to take the threats seriously and evaluate their cyber security controls.

In a survey of 140 SMBs, it was found that 40% of respondents believe they are very likely or extremely likely to experience a cyber security attack target in the next 12 months. That fear is founded, as 34% of organisations stated they experienced a malware attack in the past year, and 29% experienced a phishing or spear phishing incident. SMBs are putting their time, energy, and budget toward risk management. When it came to budgeting, 67% list their primary budgeting method as “risk-based”, and only 32% as “ad hoc/following an attack or breach”. It was found that over two-thirds of businesses would rather spend money now than pay a ransom later.

  • Talent and Governance, Not Technology, are Key to Drive Change Around Cyber Security

For the last 20 years, large organisations have been spending significant amounts of money on cyber security products and solutions, on managed services, or with consultancies large and small. Yet maturity levels remain elusive: a report found that 70% of firms surveyed had yet to fully advance to a mature-based approach. Cyber security good practices have been well established for the best part of the last 20 years and continue to provide, in most industries, an acceptable level of protection against most threats and an acceptable level of compliance against most regulations.

However cyber security is often viewed as something external to the business. This perspective leads to talent alienation and execution failures because the employees who should be invested in maintaining and improving cyber security may feel disconnected from these efforts. To make genuine progress, cyber security needs to be intrinsically linked to business values as a visible priority, owned and directed from the highest levels of an organisation.

This approach underlines the importance of governance in setting effective cyber security policies and procedures. It also highlights the crucial role of nurturing talent within the organisation to ensure active involvement in maintaining and improving cyber security measures. While technology is undoubtedly an essential element of cyber security, prioritising talent and governance can lead to lasting progress.

  • Hybrid Work, Digital Transformation can Exploit Security Gaps

A new study showed that larger organisations generally recognise malware threats but they lack protection against malicious actors and ways to properly remediate infections. The report revealed security leaders are concerned about attacks that leverage malware-exfiltrated authentication data. 53% say they are extremely concerned about attacks, with 1% of security leaders saying they weren’t concerned at all. 98% said that better visibility into at-risk applications would significantly improve their security posture.

The most overlooked entry points for malware include 57% of organisations allowing employees to sync browser data between personal and corporate devices. 54% of organisations struggle with shadow IT, due to employees’ unsanctioned adoption of applications and systems, creating gaps not only in visibility but also in basic security controls and corporate policies.

  • Human Cyber Risk Can Be Demonstrably Mitigated by Behaviour Changing Training

The process of encouraging secure cyber habits in end users is evolving from traditional awareness training toward changing end user behaviour. It reflects a growing acceptance that traditional methods haven’t worked. While traditional security awareness teaches users how to recognise social engineering, new behaviour changing trains the brain – almost pre-programs it – on the correct recognition and response to phishing.

What is considered a standard phishing email today may not be tomorrow, and changes in user behaviour will help to combat this. It is simply not enough to be shown one phishing email and be told to follow procedures. Training should instead be focused on going beyond; this should look to change how the user approaches things such as phishing, and gamifying the recognition and reporting of it.

  • AI Tool WormGPT Enables Convincing Fake Emails For BEC Attacks

A generative AI tool, WormGPT, has emerged as a powerful weapon in the hands of cyber criminals, specifically for launching business email compromise (BEC) attacks, according to new findings. The tool is designed for malicious purposes and has no restrictions on what a user can request. Such a tool allows for impeccable grammar in emails to reduce suspicion and allows sophistication with no restrictions on prompts. The lowered entry threshold enables cyber criminals with limited skills to execute sophisticated attacks, democratising the use of this technology.

https://www.independent.co.uk/tech/chatgpt-dark-web-wormgpt-hack-b2376627.html

  • Pro-Russian Hacktivists Increase Focus on Western Targets

‘Anonymous Sudan’, apparent pro-Russian hacktivists, claimed a one-hour distributed denial of service attack on the social platform OnlyFans last week. This was the latest in a string of operations aimed at targets in the US and Europe. The group’s digital assaults coincide with attacks coming from a broader network of hackers aligned with Moscow that seek attention by taking down high-profile victims and strategic targets; many of the targets support Ukraine in its ongoing war against Russia.

The pro-Russian group appears to be affiliated with Killnet, a pro-Russian hacktivist group that emerged in late 2021 or early 2022 and has claimed distributed denial of service (DDoS) attacks, data theft and leaks on perceived adversaries of the Russian government, according to an analysis from Google’s Mandiant released earlier this week. The collective’s apparent significant growth in capabilities, demonstrated by Microsoft’s confirmation that Anonymous Sudan was responsible for the outages they experienced, potentially indicates a significant increase in outside investment in the collective, further suggesting a potential tie to the Russian state.

  • Infosec Doesn't Know What AI Tools Organisations Are Using

With the marketplace awash in new artificial intelligence (AI) tools and new AI features being added to existing tools, organisations are finding themselves lacking visibility into what AI tools are in use, how they are used, who has access, and what data is being shared. As businesses try, adopt, and abandon new generative AI tools, it falls on enterprise IT, risk, and security leaders to govern and secure their use without hindering innovation. While developing security policies to govern AI use is important, it is not possible without knowing what tools are being used in the first place.

Enterprise security teams have to consider how to handle discovery, learning which generative AI tools have been introduced into the environment and by whom, as well as risk assessment.

https://www.darkreading.com/tech-trends/infosec-doesnt-know-what-ai-tools-orgs-are-using

  • Google Restricting Internet Access to Some Employees to Reduce Cyber Attack Risk

In a bid to shrink the attack surface of its employees, and thus boost security, Google is taking an experimental, and some might say extreme, approach: cutting some of their workstations off from the internet. The company originally selected more than 2,500 employees to participate and will disable internet access on the selected desktops, except for internal web-based tools and Google owned websites like Google Drive and Gmail. Some workers who need the internet to do their job will get exceptions, the company stated in materials.

Google is running the programme to reduce the risk of cyber attacks, according to internal materials. If a Google employee’s device is compromised, the attackers may have access to user data and infrastructure code, which could result in a major incident and undermine user trust. The program comes as companies face increasingly sophisticated cyber attacks. Just last week, Microsoft said Chinese intelligence hacked into company email accounts belonging to two dozen government agencies in the US and Western Europe, including the US State Department, in a “significant” breach.

  • Unlocking Business Potential: How CISOs are Transforming Cyber Security into a Strategic Asset

Enterprises are responding to growing cyber security threats by working to make the best use of tools and services to ensure business resilience, according to a recent report. Chief information security officers (CISOs) and virtual CISOs (vCISOS) in particular, want more solutions and services that help them align security measures with enterprise objectives and C-level executives have become more aware of the need for cyber resilience. As a result, security investments have expanded beyond detection and response to include rapid recovery and business continuity.

The report found that amongst other things, enterprises are investing in risk assessments and outsourcing more services. In some cases, where a CISO cannot be hired, organisations may look to hire a vCISO. It is important that the vCISO is able to understand cyber in context to the business and help to align security objectives with the organisations objectives. Black Arrow supports clients as their vCISO with specialist experience in cyber security risk management in a business context.

Black Arrow Cyber Advisory 17 July 2023 – Cisco SD-WAN vManage Vulnerable to Remote Unauthenticated Access

Black Arrow Cyber Advisory 17 July 2023 – Cisco SD-WAN vManage Vulnerable to Remote Unauthenticated Access

Executive Summary

A critical vulnerability has been identified and addressed in Cisco's network management software, SD-WAN vManage. The vulnerability allows a remote unauthenticated attacker to gain read or limited write permissions to the configuration of an affected Cisco SD-WAN vManage instance. This vulnerability only affects the REST API and does not affect the web-based management interface or the command line interface.

What’s the risk to me or my business?

A successful exploitation of the critical vulnerability allows a remote unauthenticated threat actor to read sensitive information from the compromised system, modify certain configurations, disrupt network operations. This will compromise the confidentiality, integrity, and availability of data in your organisation.

The following Cisco SD-WAN vManage versions are affected by the vulnerability:

  • v20.6.3.3 – fixed in v20.6.3.4

  • v20.6.4 – fixed in v20.6.4.2

  • v20.6.5 – fixed in v20.6.5.5

  • v20.7 – Migrate to fixed version v20.8 – Migrate to fixed version

  • v20.9 – fixed in v20.9.3.2

  • v20.10 – fixed in v20.10.1.2

  • v20.11 – fixed in v20.11.1.2

What can I do?

There are no workarounds for the critical vulnerability. As such, it is advised that patches are applied immediately.

Top Cyber Headlines of the Week

Ransomware is now the biggest Cyber Security concern for CISOs

Ransomware is the biggest cyber security concern facing businesses, according to those responsible for keeping organisations safe from hacking and cyberattacks. A survey of chief information security officers (CISOs) and chief security officers (CISOs found that ransomware is now viewed as the main cyber security threat to their organisation over the course of the next year. Almost half – 46% – of CISOs and CISOs surveyed said that ransomware or other forms of extortion by outsiders represents the biggest cyber security threat.

Crypto ransomware payments grew 311% in 2020

Crypto payments associated with ransomware grew at least 311% in 2020. “Ransomware” refers to a category of malicious computer programs that force users into paying ransoms. Just 0.34% of all cryptocurrency transactions last year were criminal, down from 2.1% in 2019. But that number is bound to go up, said the firm.

The SolarWinds hackers used tactics other groups will copy

One of the most chilling aspects of Russia's recent hacking spree—which breached numerous United States government agencies among other targets—was the successful use of a “supply chain attack” to gain tens of thousands of potential targets from a single compromise at the IT services firm SolarWinds. But this was not the only striking feature of the assault. After that initial foothold, the attackers bored deeper into their victims' networks with simple and elegant strategies. Now researchers are bracing for a surge in those techniques from other attackers.

Global Cyber Security spending to soar in 2021

The worldwide cyber security market is set to grow by up to 10% this year to top $60bn, as the global economy slowly recovers from the pandemic. Double-digit growth from $54.7bn in 2020 would be its best-case scenario. However, even in the worst case, cyber security spending would reach 6.6%. That would factor in a deeper-than-anticipated economic impact from lockdowns, although the security market has proven to be remarkably resilient thus far to the pandemic-induced global economic crisis. That said, SMB spending was hit hard last year, along with certain sectors like hospitality, retail and transport.

Cyber criminals publish more than 4,000 stolen Sepa files

Sepa rejected a ransom demand for the attack, which has been claimed by the international Conti ransomware group. Contracts, strategy documents and databases are among the 4,000 files released. The data has been put on the dark web - a part of the internet associated with criminality and only accessible through specialised software.

Ransomware provides the perfect cover for other attacks

Look at any list of security challenges that CISOs are most concerned about and you’ll consistently find ransomware on them. It’s no wonder: ransomware attacks cripple organizations due to the costs of downtime, recovery, regulatory penalties, and lost revenue. Unfortunately, cybercriminals have added an extra sting to these attacks: they are using ransomware as a smokescreen to divert security teams from other clandestine activities behind the scenes

Popular PDF reader has database of 77 million users hacked and leaked online

Ransomware victims that have backups are paying ransoms to stop hackers leaking their stolen data

Some organisations that fall victim to ransomware attacks are paying ransoms to cyber-criminal gangs despite being able to restore their own networks from backups, in order to prevent hackers publishing stolen data. Over the course of the past year, many of the most successful ransomware gangs have added an additional technique in an effort to coerce victims into paying ransoms after compromising their networks – publishing stolen data if a payment isn't received.

GDPR fines skyrocket as EU gets tough on data breaches

Europe’s new privacy protection regime has led to a surge in fines for bad actors, according to research published today. Law firm DLA Piper says that, since January 28th, 2020, the EU has issued around €158.5 million (around $192 million) in financial penalties. That’s a 39-percent increase on the previous 20-month period Piper examined in its report, published this time last year. And as well as the increased fines, the number of breach notifications has shot up by 19 percent across the same 12-month period.

Malware incidents on remote devices increase

Devices compromised by malware in 2020, 37% continued accessing corporate emails after being compromised and 11% continued accessing cloud storage, highlighting a need for organizations to better determine how to configure business tools to ensure fast and safe connectivity for all users in 2021.
