Top Cyber Stories of the Last Week

New Ransomware Victims Surge by 47% as Small Businesses Targeted

Ransomware attackers are shifting away from “big game” targets and towards easier, less defended organisations, a new report from Trend Micro has found. The report observed a 47% increase in the number of new victims of this vector from the second half of 2022, many of which were small organisations with less mature cyber postures. In fact, 57% of victims of the infamous ransomware gang LockBit, were of organisations up to 200 employees.

Small businesses can be attractive targets; they don’t have the budget of a large organisation and therefore they are more likely to have gaps that can be exploited. To combat this, small businesses need to prioritise their security budgets effectively, to allow themselves the most protection that their budget allows.

MGM Resorts Lost Millions of Dollars a Day in What Should be a Wakeup Call for Corporate Boards

The recent ransomware attack on MGM Resorts has resulted in the loss of millions of dollars daily, not accounting for ransomware fees and reputational damage. MGM Resorts are a client of Okta, who noted that Caesars entertainment and three (not named) other organisations have been hit. Although the other victims have not yet been named, it has been revealed that they are in the manufacturing, retail and technology sectors. As a result of the attacks, Beazley and AIG, who provide cyber insurance, are likely to face significant losses.

The attack should act as wakeup call for corporate boards, as it once again highlights how anyone can be a victim, and if the right controls are not in place, an attack won’t be stopped. Cyber incidents are a matter of when, not if, and boards need to ensure they are prepared, and prepared to handle the fallout when an attack happens.

SMEs Overestimate Their Cyber Security Preparedness

According to a recent report, 57% of small and medium enterprises (SMEs) have experienced a cyber security breach, with 31% facing such an incident in the past year. Despite the increasing threat, 70% are confident in their defences, though 44% solely rely on their antivirus solutions, and a quarter don't regularly train employees on cyber security best practices or never have.

The report also found that many SMEs either underestimate the importance of robust security, believing they’re too small to be targeted, or put too much trust in their current defences. The increasing number of evolving cyber threats poses a significant risk to SMEs. Rising patterns show frequent and sophisticated attacks, highlighting the urgent need for effective security measures. Understandably, not all small business owners have the resources to obtain in-house cyber security experts. Black Arrow works with organisations of all sizes and sectors to design and prepare for managing a cyber security incident; this can include an Incident Response Plan and an educational tabletop exercise for the leadership team that highlights the proportionate controls to help the organisation prevent and mitigate an incident.

China’s Hacking Power Bigger Than Rest of World Combined

In a recent conference the director of the FBI highlighted the magnitude of China’s cyber power, most notably explaining that China has a bigger hacking program than the competition combined.

This comes as recent attacks have seen malicious USB drives used to spread malware and now, something we’ve not seen much before, financially motivated hacks by Chinese-speaking actors through a piece of malware known as “ValleyRAT”.

Cyber Insurance Claims for Ransomware Reach Record High

A new report from cyber insurance provider Coalition shows a 12% increase in cyber claims over the first six months of this year, driven by the notable spikes in ransomware (19%), business email compromise (BEC) attacks (26%) and funds transfer fraud (FTF) (31%). The report found that claims severity also increased 61% from the previous six months and 117% over the last year. The average ransom demand was $1.62 million, a 47% increase over the previous six months and a 74% increase over the past year.

The report comes as the FBI and the US Cybersecurity and Infrastructure Security Agency (CISA)  released a joint advisory warning that ransomware gangs are increasingly evolving their tactics while targeting critical infrastructure sectors, including Information Technology, and Food and Agriculture. The advisory strongly discourages organisations from paying ransoms and encourages victims to report ransomware incidents to a local agency’s reporting channel. Similar advisories were released earlier in the year warning of ransomware groups such as Cl0p who exploited the vulnerability in MOVEit earlier this year.

Cyber Security Still Remains the Greatest Concern for Many C-Suite Executives

Almost three-quarters (73%) of nearly 700 board members surveyed in a new study, believe their organisations are at risk of cyber attack, including targeted attacks; a sizable increase from the 65% last year, according to a recently released Proofpoint report. Worryingly, with the high number believing they are at risk from an attack, 53% still believed they would be unprepared for such an attack. When it came to their main concerns, malware was the top concern (40%), followed by insider threat (36%) and cloud account compromise (36%).

C-suite concern has propelled budgets, with a third of businesses increasing cyber security spending by a significant margin. As IT has become less centralised with a move towards cloud-based systems, combined with a shortage of skilled cyber security workers, businesses are having to rely more heavily on third party security according to a recent report.

This investment, along with improved security communications to executives, should enhance IT upskilling and employee awareness of cyber security.

Bad Torts: Law Firms Feel the Heat from Rising Cyber Threats

Publicly available reports of ransomware attacks on law firms have accelerated this year, with massive amounts of sensitive client data now in the hands of threat actors, highlighting a growing trend of cyber incidents afflicting the legal business.

One of the reasons law firms are increasingly targeted is due to the amount of sensitive data that they hold. This data can be used for extortion, insider training and general ransom purposes. In addition, many law firms utilise third parties to handle their data, increasing their risk of becoming a victim through their supply chain.

Attacker Deepfakes IT Employees’ Voice in Phone Call to Breach Company

A recent cyber attack used AI to deepfake an IT employee’s voice. The attack started off with a phishing mail, which the unsuspecting victim employee clicked. The attacker then hit a challenge: multi-factor authentication (MFA). That was until they decided to use artificial intelligence to clone the voice of an IT employee. The attacker, now speaking as if they were the IT employee, was then able to convince the victim employee to provide the needed MFA code. As a result, the attack was successful.

The attack highlights the increase in AI for attacks, whilst also demonstrating that cyber security is more than just technology: it is people and operations too. Think about voice cloning, how would your organisation prepare for this?

Insider Risks are Getting Increasingly Costly as Organisations Fail to Proactively Address Them

With the cost of insider risk the highest it has ever been (£13.25m per incident), organisations need to effectively budget and find ways to proactively address insider risk. A report found that 55% of money spent on insider incident response went toward problems caused by negligence or mistakes, and 25% for those were caused by actively malicious insiders, with the remaining 20% being attacks that out-smarted employees.

The cost and damage is acknowledged by organisations, with a separate report finding 46% of organisations self-reported that they were actively planning to spend more on proactively addressing insider risk in 2024. Budgets are not infinite however, and organisations need to effectively allocate their spending to ensure they are getting the most protection for their spend.

Half of Executives Expect Supply Chain Challenges

With the surge in the number of attacks taking place through the software supply chain, it is no wonder almost half of executives expect supply chain challenges in the year ahead according to a survey by Deloitte. When asked about their experience, 34% of respondents self-reported that their organisation has experienced one or more supply chain cyber security events during the past year.

One of the ways to improve organisations’ supply chain security is to conduct assessments on the third parties they use, yet 21% of respondents did not do this at all. Potentially, one of the reasons for this is not knowing the correct questions to ask. Black Arrow can support you through a structured approach to asking a suite of targeted questions to your third parties, and assessing the responses for indicators of risk to your business.

How Social Engineering Takes Advantage of Your Kindness

Last week, MGM Resorts disclosed a massive systems issue that reportedly rendered slot machines, room keys and other critical devices inoperable. What elaborate methods were required to crack a nearly $34 billion casino and hotel empire? According to the hackers themselves, all it took was a ten minute phone call, allowing them to gain access through a simple social engineering attack. Social engineering psychologically manipulates a target into doing what the attacker wants, or giving up information that they shouldn’t. The consequences range from taking down global corporations to devastating the personal finances of unfortunate individual victims.

Extroverted, agreeable, and open individuals are often cyber victims; fear is an attack vector and so is helpfulness. As comfort increases, so too does vulnerability to being hacked. Social engineering attacks target both corporations and individuals. A person’s positive traits can be weaknesses against such threats. Balancing kindness with scepticism is essential.

Employers Blame Employees as 54% of Firms Face Cyber Attacks Annually

A survey found that despite the percentage of companies that have encountered a cyber security incident in the last 12 months, a worrying 24% of employees have never had any cyber security training. The survey further found that alarmingly 42% of respondents used the same password for both home and work accounts, increasing the risk of exposing their organisational passwords. This risk was furthered by 40% of the total number of respondents keeping their password in an open file or physical notebook.

Organisations, including those already providing training, should look to ensure they implement training from experts that covers such areas; by effectively training employees, organisations will increase their cyber resilience and reduce their risk of suffering a cyber attack. Black Arrow supports organisations of all sizes in designing and delivering proportionate user education and awareness programmes, including in-person and online training as well as simulated phishing campaigns. Our programmes are secure employee engagement and build a cyber security culture to protect the organisation.
