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

75% of Organisations Worldwide Set to Ban ChatGPT and Generative AI Apps on Work Devices

Newly released research found that 75% of organisations worldwide are currently implementing or considering bans on ChatGPT and other generative Artificial Intelligence (AI) applications within the workplace, with 61% stating that it will be a long term or permanent solution. Despite this, the majority recognised the opportunity such applications bring to the workplace, with 55% believing it would increase efficiency. All in all, 81% remained in favour of AI, highlighting that whilst organisations see the benefit, they are not ready to take the plunge for fear of being caught flat-footed.

Many organisations may simply not have the expertise-in house or confidence to employ AI effectively. These organisations lack an effective AI management plan, which governs the usage of AI in the corporate environment, rather than banning it outright. By having a clear-set AI plan, organisations can use AI to improve their efficiency, whilst maintaining cyber resilience. An increasing number of organisations have approached us at Black Arrow to discuss how to embrace AI securely; contact us to see how we can help you.

How an Eight-Character Password Could be Cracked in Just a Few Minutes

Strong and complex passwords are necessary to protect online accounts and data from cyber criminals. Complex passwords typically use lowercase and uppercase characters, numbers, and special characters. But complexity by itself can still open your password to cracking if it doesn’t contain enough characters, according to research by security firm Hive Systems. The report found that a complex password of eight characters can be cracked in only five minutes, and other weaker or shorter passwords are cracked instantly. However, passwords that have a greater number of characters are less vulnerable: for example an 18 character password, even if only lowercase letters, would take 481,000 years for a computer to crack.

Since creating and remembering multiple complex and lengthy passwords on your own is impossible, a password manager is your best bet. By using a password manager for yourself or within your organisation, you can generate, store and apply strong passwords for websites and online accounts.

Ransomware Victims Surge 143% as Threat Actors Pivot to Zero-Day Exploits

The number of organisations that became victims of ransomware attacks surged 143% between the first quarter of 2022 and first quarter of this year, as attackers increasingly leveraged zero-day vulnerabilities to break into target networks.

In many of these attacks, threat actors did not bother to encrypt data belonging to victim organisations. Instead, they focused solely on stealing their sensitive data and extorting victims by threatening to sell or leak the data to others. The tactic left even those with otherwise robust backup and restoration processes backed into a corner; this highlights the need for organisations to be able to detect and ideally block anomalous exfiltration of data, and have effective and rehearsed incident response plans to address the concept of pure exfiltration, because having backups is not enough.

The costs of these types of controls continue to fall making them viable for even smaller businesses. Without tools like Managed Detection and Response (MDR) and Data Loss Prevention (DLP), attacks of this nature cannot be detected until it is too late to do anything to stop them.

How Executives’ Personal Devices Threaten Business Security

Individuals, including executives, are considered a major target for cyber attacks. Motivated attackers know the right individual people they want to go after to achieve their larger organisational goal, and they’ll use any means necessary to be successful.

A recent report found that most executives are using their personal devices for work, creating a “backdoor” for cyber criminals to access large organisations. 50% of executive respondents reported receiving work-related scams in their personal emails.

Personal device use can be effective for organisations, however they need to implement an effective bring-your-own-device (BYOD) procedure and provide employees, including executives, with frequent user awareness and education training. All users at all levels within an organisation need to understand the risks, and importantly the role they play in keeping the organisation secure.

77% of Financial Firms Saw an Increase in Cyber Attack Frequency

According a recent report on the financial services sector, 77% of firms reported an increase in attack frequency, and 87% said attacks were more severe. These firms unanimously said they would look to outsource their cyber security programs to third-party providers to shore up their cyber defences. Among the respondents, firms need to protect hybrid work environments (62%), consolidate cyber security and managed IT services (41%) and tap industry-specific and regulatory expertise (33%).

Protecting Against Sophisticated Cyber Attacks Requires Layered Defences

Faced with an influx of sophisticated cyber threats, including usage of AI to further enhance the efficacy of social engineering attacks, and the growth of both malware-as-a-service (MaaS) and ransomware-as-a-service (RaaS), it is critical for organisations to invest in layered security defences.

Services like managed detection and response (MDR) are integral to monitoring, investigating and responding to threats in real time. But without a strong and comprehensive foundational cyber security posture, managed services alone cannot effectively mitigate threats. To ensure comprehensive defences against emerging threats, organisations must prioritise proactive measures that can stop attacks before they even start. As adversaries continue to refine their attack techniques, layered protection that covers every stage in the attack chain becomes imperative.

Managing Human Cyber Risks Matters Now More Than Ever

As artificial intelligence (AI) amplifies the sophistication and reach of phishing, vishing, and smishing attacks, understanding and managing human cyber risks has become increasingly vital, according to the SANS Institute. It makes sense as no matter the technological advancement, the human element has always been a point of entry for attackers.

A recent study found that mature security programs, marked by robust teams and leadership support, are characterised by having at least three full-time employees in their security awareness teams. In some cases, this isn’t feasible for an organisation and this is where outsourcing comes in. By outsourcing security awareness, organisations can ensure that they have access to security awareness experts, to keep their organisation educated. Here at Black Arrow we offer regular security and awareness training, bespoke to your organisation, for your employees and leadership team.

Hackers are Targeting Top Executives’ Microsoft 365 Accounts to Steal Work Logins

Cyber security provider Proofpoint reported that high-level execs at some of the world’s leading companies are repeatedly targeted with credential-stealing attacks. More alarmingly, according to Proofpoint, around one-third (35%) of the compromised users had multi-factor authentication (MFA) enabled.

The attacks come amid a rise in cases of EvilProxy, a phishing tool that allows attackers to steal even MFA-protected credentials. In the three months to June 2023, around 120,000 EvilProxy phishing emails were observed being sent to hundreds of targeted organisations globally, with many targeting Microsoft 365 user accounts in particular. Approximately 39% of the victims were C-level executives of which 17% were Chief Financial Officers, and 9% were Presidents and CEOs. Users must be trained effectively, to help mitigate the chance of them suffering a phishing attack. The C-suite is no exception.

UK Shaken by Major Data Breaches

Recent major data breaches impacting crucial institutions like the UK Electoral Commission (which exposed the data of 40 million UK voters) and the Police Service of Northern Ireland, have brought attention to potential risks. Following a recent freedom of information request 10,000 police officers and staff details where published including details such as first name and surname, their rank or grade and the unit and where they are based. This breach occurred when a junior member of staff forgot to remove the master spreadsheet containing sensitive data when responding to the request.

Threat of Cyber Attacks to UK National Security Upgraded: Compared to Chemical Weapons or Nuclear Attack

The UK government has raised the threat level posed by cyber attacks, now deeming the risk of cyber attacks to be more severe than that presented by small-scale chemical, biological, radiological, or nuclear (CBRN) attacks according to the latest National Risk Register (NRR) report for 2023. The report also highlighted artificial intelligence (AI) as a “chronic risk” – that is, one that poses “continuous challenges that erode our economy, community, way of life, and/or national security”.

Mac Users are Facing More Dangerous Security Threats Than Ever Before

Apple’s MacBook Pro or iPhone devices are often perceived as safer, from a cyber security standpoint, compared to those from Microsoft or Google, mostly because of its “walled garden” approach. However, another key reason why hackers were not historically as interested in Apple was the smaller market share Apple held. That is no longer the case and as attacks are rising against Apple devices, this is something we expect to see continuing to accelerate.

In the last 10 years, Apple’s market share on desktop has increased from less than 7.5% to just over 20% today. Apple frequently patches actively exploited vulnerabilities, with overall 261 security vulnerabilities addressed so far this year. A recent report found that Mac users are targeted by three key threats: Trojans, Adware, and Potentially Unwanted Applications (PUA). Of the three, Trojans are the biggest single threat, making up more than half of all threat detections. Of all those detections, around half (52.7%) were for the EvilQuest encryption malicious software.

Cyber Attack to Cost Outsourcing Firm Capita up to £25m

Capita expects to take a financial hit of as much as £25m as a result of a cyber attack that began in March, pushing the outsourcing group to a pre-tax loss of almost £68m for the first half of the year. The group is still recovering from the attack by the Black Basta ransomware group, which hacked its Microsoft Office 365 software and accessed the personal data of staff working for the company and dozens of clients. Capita, which runs crucial services for local councils, the military, and the NHS, estimated that the financial costs associated with what it called the “cyber incident” would be between £20m and £25m. Previous estimates had put the cost at £15m to £20m.

The group said this new figure reflected the complexities of analysing the “exfiltrated” data, as well as costs of recovery and remediation and new investment to improve its cyber security. However, Capita said it was not currently able to estimate the level of any potential fine related to the incident and had not yet made any provision to cover any future costs. The company’s shares fell by more than 12% in morning trading on Friday after the release of its results, making it the biggest faller on the FTSE 250.

Government and Public Services Face 40% More Cyber Attacks and Struggle to Protect Due to Lack of Resources

A report published by BlackBerry noted a 40% rise in cyber attacks against public sector organisations and government institutions. One of the reasons is the limited resources and resistance that these government and public have; this makes it much easier for an attacker. An easy target is an attractive target.

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.

https://technative.io/talent-and-governance-not-technology-are-key-to-drive-change-around-cyber-security/

  • 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.

https://www.msspalert.com/cybersecurity-research/digital-transformation-hybrid-work-models-create-perfect-setting-for-cybercriminals-to-exploit-security-gaps-study-finds/

  • 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 30/09/2022 – Microsoft SQL Servers Targeted by FARGO Ransomware

Executive Summary

Unsecured Microsoft SQL servers have been identified as the target for FARGO Ransomware (aka Mallox, aka TargetCompany). This ransomware strain attempts to shut down various processes and services on affected machines before encrypting the data and supplying a ransom note, which contains a warning that data may be published on the public domain if payment is not received.

What’s the risk to me or my business?

At current the threat actors appear to be targeting vulnerable Microsoft SQL servers and gain initial access through either credential brute forcing or through known vulnerabilities that have not been patched. If the threat actor gains access to this server and successfully delivers the ransomware, then data could be encrypted and published on the public domain.

What can I do?

Ensure that leading practices are followed for securing Microsoft SQL servers, including both timely patching of security vulnerabilities when made available, and ensuring that server administrator accounts are protected with strong passwords and multi-factor authentication where available.

Technical Summary

The attack unfolds by first a threat actor having initial access to the MS-SQL process, allowing them to execute a .net file through either CMD or Powershell. This file downloads additional malware, which then generates a .BAT file that shuts down certain processes and services. The ransomware is then injected into AppLaunch.exe, which is a normal windows program. It attempts to delete a registry key, executes recovery deactivation and closes some additional processes including the MS-SQL server. This allows access to the database offline, which allows for the files to be encrypted with the .FARGO3 extension. A ransomware note named ‘RECOVERY FILES.TXT’ is then generated, detailing payment, with a warning that data will be published on the public domain if the payment is not received.
