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.
