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

UK Ministers Publicly State Fears of Potential Widescale Power Grid Disruptions

The UK’s power network has long been an attractive target for enemies of the state and that remains true today. In fact, according to the UK Government, the risk of the whole country’s electricity system being shut down is growing. So are the dangers to citizens if it happens.

The UK’s National Risk Register, the official document assessing 89 different possible threats to the country, explains that a cyber attack on the National Grid could be launched by culprits “encrypting, stealing or destroying data upon which critical systems depend, or via disruption to operational systems”.

Countries Brace for Influence Operations, AI and Hacking Campaigns Ahead of Historic 2024 Election Year, Could Upset World Balance

Billions of people around the world are expected to go to the polls and vote in 2024, in what will be the most significant election year in recent memory, and cyber security and government officials have already warned about countries using technology to influence operations. This includes disinformation campaigns and hacking attempts. Officials have further warned that artificial intelligence will likely be used to fuel such campaigns.

The Most Popular Passwords of 2023 are Easy to Guess and Crack

NordPass released a list of the top 200 common passwords recently, which included “123456” and “admin” as the top two. Of particular note, the top 40 passwords were all deemed to take less than 12 seconds to crack, or could be determined by an actor with no knowledge of the password. Many people would argue that there are so many passwords needed these days that it becomes hard to remember, hence their choice of easier passwords, and often reusing or recycling them across multiple sites and services. The use of a password manager can greatly reduce this need, requiring the user to only remember one password whilst also allowing for more complex and harder to crack passwords.

Dangerous Malware Pretends to be Some of Your Most Used Business Software

Hackers are using an old form of banking malware, known as Carbanak, to launch damaging ransomware attacks. Hackers are using compromised websites to host the malware, impersonating popular business-related software such as HubSpot, Veeam, or Xero.

MFA Helps You Stay Resilient, But Nothing is a Silver Bullet

Multi-factor authentication (MFA) is a great resource for improving your organisation’s cyber resilience, but no technology is 100% secure and the human element will nearly always remain. With notable security breaches bypassing MFA to compromise organisations including Uber, games company EA, and authentication business Okta, organisations need to be aware that it is a possibility. As such, organisations need to ensure they implement MFA effectively and educate their users in their implementation; even the strongest of controls are rendered useless if they can be bypassed with one social engineering phone call.

Ransomware Leak Site Victims Reached Record-High in November

Corvus Threat Intel observed 484 new ransomware victims posted to leak sites in November. This represents a 39% increase from October and a 110% increase compared with November 2022. Further, this is the eleventh consecutive month in which there has been a year-on-year increase in ransomware victims, and the ninth with a victim count over 300.

MOVEit, Capita, CitrixBleed and More: The Biggest Data Breaches of 2023

2023 was a colossal year for data breaches, with the likes of MOVEit, Capita, Citrix, Royal Mail, MGM resorts and 3CX among some of the most significant victims. Such attacks have involved a number of vectors, such as file transfer vulnerabilities, social engineering, supply chain attacks and zero-day exploits. The result? Millions of people’s data compromised, and hundreds of millions paid out to attackers; the attack on MGM resorts alone is reported to have costed upwards of $100 million.

Europol Warns 443 Online Shops Infected with Credit Card Stealers

Europol has notified over 400 websites that their online shop had been hacked, with malicious scripts that steal card information from paying customers. The scripts are designed to intercept and steal payment card numbers, expiration dates, verification numbers, names, and shipping addresses, which are then uploaded to an attacker. This information is then used, or sold on the dark web to be used. Unfortunately, some of these attacks can go undetected for weeks or even several months.

Physical Access Systems Open Door to IT Networks

Cyber attackers can exploit access control measures installed on supposedly secure facility doors to gain unauthorised building access to sensitive locations, as well as breach internal IP networks directly from these systems, research has shown. At a recent leading security conference, analysts demonstrated this is an attack. Assets such as these can often be forgotten about and therefore omitted from protections, highlighting the need for organisations to have an up to date and accurate asset register.

Simple Hacking Techniques Prove Successful in 2023 Cyber Attacks

Hacking can be sophisticated, but often it is not sophisticated at all. Some of the biggest hacks this year started with what seemed like an innocent phone call, but which in fact were fairly simple social engineering attacks. Additionally, hackers continued to target companies that failed to promptly update their systems, even after patches were released to fix critical vulnerabilities. The best first step to protect an organisation is to establish a culture of good cyber security hygiene across people, operations and technology.

Daily Malicious Files Rise to 411,000 a day in 2023

Cyber criminals unleashed an average of 411,000 malicious files every day in 2023, representing a 3% increase from the previous year, according to Kaspersky. Malicious desktop files in particular rose by 53%. Cyber criminals favoured Microsoft Office services’ vulnerabilities, which represented 69% of all exploited vulnerabilities.

Android Malware Actively Infecting Devices to Take Full Control

Android Malware is actively being used to take control of devices for illicit purposes, such as stealing sensitive information and enabling remote attacks, and least 327,000 devices are reported to have been infected with such malware. Research has found that amongst the most targeted countries are the UK and US. Often, for the malware to work, users need to allow it access to information such as contacts, email. In some cases, the user would only be aware they have consented if they were to manually check the apps settings. For organisations, this can mean employees bringing personal or work phones into the corporate environment, with malware potentially along for the ride.

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.
