Black Arrow Cyber Threat Briefing 18th August 2023

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

Ransomware Group Targeting MSPs Worldwide in New Campaign

Russia-based cyber attackers called Play are evolving, with the ransomware group now using remote monitoring and management (RMM) tools at outsourced IT providers or managed service providers (MSPs) to gain access and hit downstream customers. A significant number of eventual targets are medium sized business. The group is also utilising intermittent encryption, where files are only partly encrypted, to avoid detection.

The attacks highlight the need for organisations to be aware of where they are in the supply chain and how they can be targeted through their supplier. It is not enough for an organisation to focus on its own security in isolation; organisations also need to have a way of effectively assessing their supply chain risk which includes their MSP.

As Ransomware Surges, A lack of Resources Makes SMBs Most Vulnerable

Ransomware attacks continue to increase, with 1500 victims confirmed this year. It is likely this figure will continue to rise. In parallel, criminals are evolving and with that comes a rise in triple extortion; attackers are not just encrypting and exfiltrating an organisation’s data, but also using this data to blackmail employees and target third parties, hitting the supply chain.

Unfortunately for SMBs, they do not have the resources to keep up with such attacks, making them the most vulnerable. A report found that organisations that had 51 to 200 employees were the most targeted, followed by organisations with 11 to 50 employees. When it came to the types of organisations, the Financial Services sector placed first.

This should not mean SMBs should just accept this and wait to be attacked; on the contrary, their increased vulnerability means that SMBs need to effectively prioritise and allocate resources, and if necessary getting in specialist external help, to ensure their protections are the best that resources allow.

Business Email Compromise Attack Costs Far Exceeding Ransomware Losses

Cloudflare's 2023 Phishing Threats Report recorded a 17% spike in business email compromise (BEC) related financial losses between December 2021 and 2022, noting that threat actors are increasingly leaning on this attack method to target organisations. Additionally, across 2022 nearly three-quarters (71%) of respondents to the study said they experienced an attempted or successful BEC attack. The Cloudflare report found that the financial impact of BEC led to organisations suffering losses in excess of $2.7 billion, whereas ransomware caused losses of $34.3 million during the same period.

Email Phishing Remains the Main Entry for Cyber Criminals; People with Six Personality Traits are More Susceptible

According to a report, phishing attacks were found to be the initial attack vector for nine in ten cyber attacks. The report found that the focus of a cyber criminal tended to be two objectives: achieving authenticity and getting victims to click. Worryingly, 89% of unwanted messages were found to have bypassed authentication checks, leaving people and procedures as the last line of defence in an organisation.

A separate study found that having the following traits made a user more susceptible to phishing: extroverted, agreeable, people-pleasing, quick to trust, fearful or respectful of authority, and poor self-control.

With employees playing such an important role in preventing phishing, organisations need to ensure that employees are aware of what to look for in a phishing email with regular training to account for evolving tactics. This training should be carried out by experts with experience of conducting phishing simulations, accompanied with the ability to educate users on how they can protect themselves from falling victim.

Gartner Study Finds Generative AI to be a Top Emerging Risk for Organisations

In a recent survey, Gartner found that generative AI models such as ChatGPT were the second greatest emerging risk, with concerns around data privacy. This has led to organisations looking to ban such AI, with a separate report by Blackberry finding that ChatGPT faced banning from 75% of organisations.

Banning AI in the organisation is a short-term solution. The benefits of AI are clear and its usefulness in an organisation is significant, with reports finding 75% of IT leaders in favour. Organisations should instead look at how they can govern the usage of AI in their organisation, to reduce the risk of AI-related incidents and improve the effectiveness of work.

LinkedIn Suffers Significant Wave of Account Hacks

LinkedIn users are reporting losing access to their accounts, with some being pressured into paying a ransom to get back in or else face permanent account deletion. LinkedIn is no stranger to being a target of cyber criminals; last year, the platform was deemed the most abused brand in phishing attempts likely due to its recognisability and widespread use in the corporate world. This extended as far as threat actors using fake LinkedIn profiles.

With the number of accounts being compromised, users need to be vigilant in their use of LinkedIn and be on the lookout for suspicious messages. Black Arrow recommends that users ensure they are using strong and unique passwords, combined with multi-factor authentication (MFA) to protect themselves.

High Net-Worth Families are at Risk of Cyber Crime

A report found that high net-worth families have prioritised cyber security with a notable 77% of respondents stating they had a cyber security plan; however, 55% said their plan “could be better”.

A cyber security plan is not optional anymore. High net-worth families are at increased risk, with criminals cottoning on to the amount of information that is out there and the financial gain that can be made if that information is used effectively. Social media is just one of the things increasing the risk of cyber crime; unbeknownst to some families, their social media may be providing criminals a treasure trove of insight into a family’s wealth, real-time location and habits. Such information can be used by a cyber criminal to employ attacks.

Cyber Attack Rule Raises Insurance Risks for Corporate Officers

The US Securities and Exchange Commission (SEC) recently issued rules that formally outlined directors’ responsibilities in cyber security governance for the first time, laying the groundwork for potential enforcement actions. The recently issued rules bring potential regulatory probes and shareholder legal class action alleging senior executives failed to supervise their businesses’ cyber security practices.

Although the practice is not yet universal, a growing number of director and officer (D&O) policies are being drafted with cyber related exclusions. Meanwhile, most cyber insurance policies exempt SEC enforcement actions and investor claims, but some cover allegations against a company’s executives over their cyber security roles.

Whilst this is only in the US at the moment, other developed nations are likely to follow suit.

PSNI and UK Voter Breaches Show Data Security Should be Taken More Seriously

The Police Service of Northern Ireland (PSNI) and the UK Electoral Commission both suffered cyber incidents on the same day. Whilst both incidents were different in how they happened, the result was the same: sensitive information had been leaked. In the case of the PSNI, the data was leaked through a response to a freedom of information (FOI) request, in which an Excel sheet was accidentally included by the PSNI. The Electoral Commission incident resulted from a cyber attack.

The incidents are a wake-up call for organisations. If you have not already done so, you need to put things in place to help protect your data from ending up online. The PSNI incident in particular highlights the need to ensure that data does not leave the organisation by accident.

The Imperative of Cyber Preparedness: The Power of Tabletop Exercises

Cyber security has become an inescapable concern for organisations across industries. With cyber threats ranging from data breaches to ransomware attacks, it is paramount that companies remain vigilant and prepared.

A key way to be prepared is through a tabletop exercise that simulates a hypothetical cyber security incident and helps organisations to practice and evaluate their response. One example scenario can be responding to a ransomware attack blocking access to the organisation's computers for a ransom. These exercises serve as a practical, engaging, and low-risk way for teams to identify vulnerabilities in current plans, improve coordination, and evaluate the decision-making process during a crisis and this is something that we do with our clients on a regular basis.

Why Are Phones a Cyber Security Weak Spot?

Mobile phones are more interconnected than ever, with their usage extending to the workplace. Despite this, they often enter the corporate environment with a lack of protection and oversight. When laptops are in the corporate environment they are often secured through methods such as encryption and often the organisation has a clear oversight of the applications and activity on the laptop. Mobile phones on the other hand, are often left unmonitored, despite the fact they can and often do carry sensitive information.

Mobile phones also carry additional risks; for a start, they are easier to lose, due to their size difference and the fact they are often out more. In addition, they may have more entry points. Internet of things (IoT) devices, such as smart appliances, are often controlled by phones, making them another entry point for an attacker.
