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.

Source: [Bleeping Computer]

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

Cloud Hosting Firm Loses All Customer Data After Ransomware Attack

CloudNordic, a Danish cloud hosting provider, has told customers to consider all of their data as having been lost following a ransomware infection that encrypted the large Danish cloud provider. The threat actors had destroyed the organisation’s backups, which prevented the firm from recovering effectively. The attack also impacted AzeroCloud, which is owned by the same company.

Worryingly, many organisations believe that having backups and using the cloud is enough for them to be able to recover from any cyber incident; unfortunately, as shown in the CloudNordic and AzeroCloud attacks, it is not enough. Organisations need to have a recovery plan in place which is tested and improved, to best strengthen themselves in the event of a cyber incident.

Would You Infect Others to Rid Yourself of Ransomware?

Hackers continually develop ransomware with new and creative attack methods that keep internet security professionals on their toes and pose challenges for people trying to detect threats. Victims of ransomware usually see messages asking them to pay for file access restoration; however, the Popcorn Time ransomware group takes a different approach to getting victims involved.

The Popcorn Time ransomware approach works via the referral method. The ransomware group is willing to give victims access to their files if they send the referral link to two other people, extending the attacker’s reach. Most people would hesitate to distribute a ransomware link through email, WhatsApp, or another method that is easy for victims to identify them as the perpetrators. Law enforcement bodies categorise ransomware attacks as crimes that come with hefty fines and prison time. Even those choosing to send the links to people they know face disastrous consequences beyond law enforcement, including the loss of jobs and relationships.

Artificial Intelligence and USBs Drive 8% Rise in Cyber Attacks

Checkpoint’s 2023 Mid-Year Security Report shows an 8% surge in global weekly cyber attacks during Q2, marking the most significant increase in two years. The report highlights the fusion of advanced artificial intelligence (AI) technology with traditional tools like USB devices used for disruptive cyber attacks.

Other significant findings include the evolution of ransomware tactics. The report found that ransomware groups are exploiting vulnerabilities in common corporate software and shifting focus from encrypting data to stealing it. USB devices have resurfaced as threats, employed by both state-affiliated groups and cyber-criminals to distribute malware globally. The misuse of AI has escalated, as attackers use generative AI tools for phishing emails, keystroke monitoring malware and basic ransomware code.

Ransomware Attacks Broke Records in July, Mainly Driven By One Group

A number of ransomware actors are utilising the threat of releasing sensitive data to get organisations to pay ransoms; in some cases this is combined with encryption to give the actor two avenues of payment. A report has found there were over 500 attacks last month, an increase of 153% compared to one year ago, and a 16% increase compared to June. Within Europe, there was a 59% increase in ransomware attacks from June to July.

Part of the significant rise is due to the ransomware group called Cl0p, whose attack on the MOVEit software has accounted for hundreds of victims this year. The Cl0p ransomware group has kept its promise to publish files on the clearweb of all its victims if contact was not made. The clearweb is simply what we know as the internet; anyone can access it. As such, there will be many organisations who are now having their sensitive data published and readily viewable for anyone who has access to the internet.

Cyber Risk in The Boardroom

The relationship between the CISO and the wider boardroom has become increasingly cooperative, with 77% of CEO’s seeing cyber as a strategic function and a potential source of competitive advantage. While it is ultimately up to the board to take steps to keep cybersecurity high on the agenda, the CISO also has a responsibility to press the message and bridge any gaps.

CISOs must deliver concerns, strategies and recommendations in a business-first manner, while avoiding jargon and overly technical language. Attracting and retaining good quality senior security professionals is very challenging in the current market and Black Arrow offer a fractional CISO service, giving access to a whole team of specialists with wider expertise, experience and backgrounds, for less than the cost of hiring one individual.

Malware-Infected Advertising Grows Ever More Sophisticated, And More Damaging

The malware exploits known as malware-infected ads, or malvertising, have been around for decades, but new reports point to a steady rise in efficacy. With malvertising, the infected ads are typically placed on legitimate ad networks, which makes them more difficult to spot and remove. The technique continues to use more and more sophisticated mechanisms for getting their infections spread throughout the web and keeping them running for a long time. The exploits can operate in one of several ways, including intercepting a user’s clickstream on random hyperlinks and substituting them with redirects to advertising websites.

Adblockers either on endpoints or at the network level can also help to prevent malvertising from causing harm.

Cyber Security is Everyone’s Responsibility

A recent survey found that 41% of respondents said that poor quality training, or a lack of training altogether, and insider threats were impacting their organisation’s security. Cyber security involves everyone as any employee can be an entry point for a cyber incident, but they also have the power to prevent one. It is important to make sure all employees are provided adequate training. Not every role requires the same training however, so it is important for organisations to identify and provide training that is appropriate to employees. Black Arrow provide live in person and online instructor lead cyber security training, both through Cyber Risk and Governance Workshops for Senior Leadership and Awareness, Behaviour and Culture Training for employees and contractors.

QR Code Hacks Are Another Thing to Worry About Now

One of the upcoming technologies thrust upon us is QR codes. At this point, you can find them at most restaurants and parking sites. You simply scan the code and you are taken to the relevant site, for example, the menu for the restaurant. Attackers have cottoned on to this and started to use QR codes in phishing attacks; the idea being that the victim will scan the code without scrutinising it and be taken to a malicious website instead.

Security Basics Aren’t So Basic Anymore

The basics of cyber security, it turns out, aren’t so basic anymore. What was considered basic has moved way beyond just having firewalls and antivirus, and the most basic controls nowadays include more advanced controls such as robust identity and access management, multi-factor authentication (MFA) and patching and vulnerability management. Many of these now basic controls are lacking or non-existent across the economy according to cyber security experts. A report found that only 28% of Microsoft users had MFA enabled as 2022 closed.

You can’t solve all the problems at once. However, progress on these fronts also relies heavily on the need for a cultural shift. Organisations need to get to the point where they view cyber security in the same light as locks on doors and seatbelts in cars.

Apple MacOS Security Myths

Apple has maintained a reputation as being more secure than other manufacturers, and whilst Apple has put many different security mechanisms into its operating system, no technology is bulletproof. Assuming an Apple device is invulnerable can lead users to believe that their Mac will not get viruses or be subject to a plethora of other cyber threats. As a result, this can lead to poor cyber hygiene from the individual, as they assume they are safe regardless of what they do. Apple users need to remain every bit as aware of risks, social engineering, keeping devices up to date, and having appropriate security controls.

Security Leaders Report Misalignment of Investments and Risk Reduction

The cyber risk landscape was analysed in a recent report that examined the amount of risk that organisations are willing to accept, their resource constraints and key priorities for approaching cyber risk in the future. The report found 66% of respondents indicating that they have limited visibility and insight into their cyber risk profiles, hindering their ability to prioritise investments and allocate resources effectively. 67% of organisations experienced a breach requiring attention within the last two years despite having traditional threat-based security measures in place. Further, 61% of security executives expressed concerns over the current misalignment between cyber security investments and their organisation's risk reduction priorities.

Many CISOs Tout SaaS (Cloud) Cyber Security Confidence, but 79% Admit to Incidents

Cyber security, IT, and business leaders alike recognise SaaS (cloud) cyber security as an increasingly important part of the cyber threat landscape. And at first glance, respondents appear generally optimistic about their SaaS cyber security as 85% answered that they are confident or very confident in their company's or customer's data security in sanctioned SaaS apps.

Despite the confidence, 79% of respondents confirmed that their organisation had identified SaaS cyber security incidents over the past 12 months. Many of those incidents occurred in environments with cyber security policies in place and enforced, as 66% of respondents claimed in their responses.

If You Ever Used Duolingo, Watch Out for Phishing Email

Users of Duolingo, past and present, should be wary of phishing emails as data on about 2.6 million accounts were scraped through an exposed application programming interface (API), and then offered on a hacking forum back in January. Login and real names, email addresses, phone numbers, and courses studied were part of the collection, which went for $1,500. Now that data has resurfaced on a different forum, and at a substantially lower cost of just a few dollars, users of the service can expect this data to be used in fresh phishing campaigns.

91% of Security and IT Professionals: Criminals are Already Using AI in Email Attacks

Recent research found that 91% of security and IT professionals are noticing cyber criminals already using AI as part of email attack campaigns, with 74% indicating they have experienced an increase in the use of AI by cyber criminals in the past six months. This is worrying as 52% reported that email security is among one of their top three concerns.

Organisations need to make sure that their technologies, procedures and policies are updated to factor in AI-enabled email attacks to help reduce the risk they pose to the organisation. Such improvements should also include employees.
