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 The historical view of cyber security as merely a component of broader risk strategies is outdated; it now demands a central role in safeguarding against operational, financial, and reputational threats.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.

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.

Black Arrow Cyber Advisory 19/07/2022 – Microsoft identifies Phishing campaign which can bypass MFA if additional controls are not in place

Executive Summary

Microsoft has released information on a new phishing campaign involving “adversary-in-the-middle” AiTM techniques, which has affected more than 10,000 organisations since September 2021. What is unique about this particular attack method is that it has the potential to bypass Multi-Factor Authentication (MFA). It is important to note that this attack does not make use of a vulnerability within MFA, and that MFA is still a key control in preventing credential compromise.

What’s the risk to me or my business?

As more organisations implement security controls such as MFA, malicious actors will be looking into possibilities of targeting these controls. This particular attack technique involves a proxy server being deployed in between the recipient and a valid targeted website. In short, a targeted user would receive a phishing email, the link to the phishing email would resolve in a valid website, with the traffic being re-directed through the server of a malicious actor. This allows the malicious actor to steal “authenticated session cookies”, after the user has logged into the valid website. The malicious actor can then use the authenticated session cookies to access the valid website with the targeted users credentials, which can then lead to further attacks such as Business Email Compromise as shown in the diagram below.

Figure 1: Overview of AiTM phishing campaign and follow-on BEC (Microsoft 365 Defender Research Team, 2022)

What can I do?

Microsoft recommends implementing conditional access policies, which can limit user access in different scenarios, such as only allowing access to trusted locations, compliant devices or trusted IP addresses. This would prevent a stolen session cookie from granting access to an account outside of these conditions. Anti-Phishing solutions can also be used to block phishing emails from arriving in end-users inboxes, however it is worth noting that these solutions may not be able to block every threat. Where possible, security monitoring should be in place to detect suspicious sign-in attempts, and unusual mailbox activities including external forwarding, rule creation and access from untrusted IP addresses or devices.

It is also critically important that technical controls such as MFA are supplemented with end-user training, including Phishing simulations as it is the primary ingress point for this type of attack.

Technical Summary

Microsoft has published a full breakdown of sample attacks that they have monitored. So far they have followed the following process:

1. An attacker sends emails containing an HTML file attachment, stating that a voicemail has been received on their Microsoft account. This email follows the same template which is received when a user receives a voicemail via Microsoft Teams.

2. The user clicks on the HTML attachment, which takes them to a website displaying the mp3 file being downloaded. No actual download takes place, but a progress bar is updated.

3. The user is then re-directed to a gatekeeper, which confirms that the user has clicked on the html attachment.

4. The user arrives at a proxied version of the Microsoft Azure Active Directory login page. It is important to note that if an organisation has customised this landing page with their corporate logo then this will also be displayed, making the website seem even more legitimate.

5. The user enters their credentials which are then authenticated by Microsoft. If MFA is enabled, the user would be prompted for MFA at this stage.

6. The user is re-directed to the official Microsoft 365 website, while the authenticated session cookies are captured by the attacker, also allowing them into the official Microsoft 365 website.

7. Microsoft’s research has then shown that the stolen session is used for Business Email Compromise (BEC) attacks, targeting finance related emails within the targeted users inbox to request fraud payments. At this stage however a malicious attacker also has potential to access any 365 service which the targeted user has access to.

Appropriate conditional access controls could prevent an attacker at step 6 from using the stolen cookies to access the targeted users Microsoft 365 account.

61 Percent Of Employees Fail Basic Cyber Security Quiz

Nearly 70% of employees polled in a new survey said they recently received cyber security training from their employers, yet 61% nevertheless failed when asked to take a basic quiz on the topic. This was one of the leading findings of a research study that sought to understand the cyber security habits of some 1,200 workers, as well as their knowledge of best practices and ability to recognize security threats.

More Than 1,900 Distinct Hacking Groups Are Active Today

There are currently more than 1,900 distinct hacking groups that are active today, a number that grew from 1,800 groups recorded at the end of 2019. In its yearly cyber crime report, the company said it discovered 650 new threat actors during 2020, but new evidence also allowed it to remove 500 groups from its threat actor tracker due to overlaps in activity and hacking infrastructure with previously known clusters.

Ransomware: The Internet's Biggest Security Crisis Is Getting Worse

Organisations continue to fall victim to ransomware, and yet progress on tackling these attacks, which now constitute one of the biggest security problems on the internet, remains slow. From small companies to councils, government agencies and big business, the number and range of organisations hit by ransomware is rising. One recent example; schools with 36,000 students have been hit, leaving pupils without access to email as attempts were made to get systems back online. That is at least four chains of schools attacked in the last month.

Enterprise Security Attackers Are One Password Away From Your Worst Day

If the definition of insanity is doing the same thing over and over and expecting a different outcome, then one might say the cyber security industry is insane.

Criminals continue to innovate with highly sophisticated attack methods, but many security organisations still use the same technological approaches they did 10 years ago. The world has changed, but cyber security hasn’t kept pace.

Distributed systems, with people and data everywhere, mean the perimeter has disappeared. And the hackers couldn’t be more excited. The same technology approaches, like correlation rules, manual processes and reviewing alerts in isolation, do little more than remedy symptoms while hardly addressing the underlying problem.

Credentials are supposed to be the front gates of the castle, but as the SOC is failing to change, it is failing to detect. The cyber security industry must rethink its strategy to analyse how credentials are used and stop breaches before they become bigger problems.

Microsoft’s April Update Patches 114 Bugs—Half Of Which Allow Remote Code Execution

The fourth Patch Tuesday of 2021 is another big one. Today, Microsoft revealed 114 vulnerabilities fixed in the monthly security, over half of which could potentially be exploited for remote code execution by attackers. Of the 55 remote execution bugs, over half were tied to Windows’ Remote Procedure Call (RPC) interface. Four more were Microsoft Exchange bugs (all urgent fixes) reported to Microsoft by the National Security Agency. In addition, six Chrome vulnerabilities that were previously addressed by Google are included in the roll-up.

Nation-State Cyber Attacks Targeting Businesses Are On The Rise

Businesses are increasingly coming under fire from nation state-backed hackers as governments around the world engage in attacks to steal secrets or lay the foundations for future attacks. Nation States, Cyberconflict and the Web of Profit, a study by cyber security researchers at HP and criminologists at the University of Surrey, warns that the number of key nation-state attacks has risen significantly over the past three years – and that enterprises and businesses are increasingly being targeted. An analysis of nation-state cyber attacks between 2017 and 2020 reveals that just over a third of organisations targeted were businesses: cyber defence, media, government, and critical infrastructure are all also common targets in these attacks, but enterprise has risen to the top of the list.

Cyber Criminals Are Installing Cryptojacking Malware On Unpatched Microsoft Exchange Servers

Cyber criminals are targeting vulnerable Microsoft Exchange servers with cryptocurrency mining malware in a campaign designed to secretly use the processing power of compromised systems to make money. Zero-day vulnerabilities in Microsoft Exchange Server were detailed last month when Microsoft released critical security updates to prevent the exploitation of vulnerable systems. Cyber attackers ranging from nation-state-linked hacking groups to ransomware gangs have rushed to take advantage of unpatched Exchange servers -- but they are not the only ones.

NAME:WRECK DNS Vulnerabilities Affect Over 100 Million Devices

Security researchers have disclosed nine vulnerabilities affecting network communication stacks running on at least 100 million devices. Collectively referred to as NAME: WRECK, the flaws could be leveraged to take offline affected devices or to gain control over them. The vulnerabilities were found in a wide range of products, from high-performance servers and networking equipment to operational technology (OT) systems that monitor and control industrial equipment. According to researchers threat actors could exploit NAME:WRECK vulnerabilities to deal significant damage to government or enterprise servers, healthcare facilities, retailers, or companies in the manufacturing business by stealing sensitive data, modifying or taking equipment offline for sabotage purposes.

Brits Still Confused By Multi-Factor Authentication

The British public are still woefully underinformed and unaware of the security benefits of multi-factor authentication (MFA). The industry association, founded in 2012 to promote authentication standards and reduce global reliance on passwords, recently polled over 4000 consumers in the UK, France, Germany, and the US. It revealed that half (49%) UK consumers have had their social media accounts compromised or know a friend or family member who has. However, despite a continued number of high-profile account takeovers, 43% said this does not make them enhance security on their accounts, even though they “feel like” they should. Part of the problem seems to be a general lack of understanding about the benefits of MFA in protecting account holders from phishing, as well as credential stuffing and other brute force attack types. Although such features are offered by all social media companies today, over a quarter (26%) of respondents said they were not using or didn’t know about them.

623K Payment Cards Stolen From Cyber Crime Forum

The Swarmshop cyber underground “card shop” has been hit by hackers, who lifted the site’s database of stolen payment-card data and leaked it online. That is according to researchers, who said that the database was posted on a rival underground forum. Card shops, are online cyber criminal forums where stolen payment-card data is bought and sold. Researchers said the database in question contains 623,036 payment-card records from card-issuers in Brazil, Canada, China, France, Mexico, Saudi Arabia, Singapore, the U.K., and the U.S.
