In this Cyber Brief we have included several significant vulnerabilities and associated advisories reported in August 2023.
Europe
Cyber policy and law enforcement
| The EU examines the impact of social media in society The EU's Digital Services Act (DSA) mandates that major online platforms with over 45 million users in the European Union, including Instagram, Snapchat, TikTok, Pinterest, and YouTube must comply with extensive rules by the end of August. The platforms must provide their first yearly assessment of how their design, algorithms, advertising, and terms of service impact societal issues, proposing and implementing measures under scrutiny. Regulations include preventing algorithms from recommending harmful content to minors. | Regulation | |
| Qakbot malware infrastructure takedown On August 30, Europol and Eurojust announced they had supported the coordination of a large-scale international operation that has taken down the infrastructure of the Qakbot malware. The operation also led to the seizure of nearly 8 million Euros in cryptocurrencies. The operation involved judicial and law enforcement authorities from France, Germany, Latvia, The Netherlands, Romania, the UK and the US. Qakbot, operated by a group of organised cybercriminals, targeted organisations across multiple countries, stealing financial data and login credentials. Cybercriminals used this persistent malware to commit ransomware, fraud, and other cyber-enabled crimes. | Takedown | |
| Hosting provider of illicit material taken down Authorities from the US and Poland have collaborated to shut down the well-known "bulletproof" (very permissive to the content allowed) hosting platform Lolek Hosted, which was being used by cybercriminals for malicious activities. Bulletproof hosting providers offer anonymity to hackers and are commonly used for distributing malware and supporting cyberattacks. | Takedown | |
| London jury convicts two Lapsus$ operators A London jury convicted two members of the Lapsus$ Group for their roles in multiple data theft-and-leak operations. Lapsus$ is a group that has conducted data theft extortion operations since mid-2021. They are motivated by both financial gain and a desire for notoriety. Arion Kurtaj, an 18-year-old operator, was found guilty of various offences, and an unnamed 17-year-old operator was found guilty of fraud, blackmail, and a Computer Misuse Act offence. | Sentence |
Cyberespionage
| Ukraine thwarted a Russian cyber operation On August 8, the Security Service of Ukraine (SBU) and the Armed Forces of Ukraine announced they had successfully thwarted a cyber operation conducted by Russian military intelligence (GRU) aimed at infiltrating the Defence Forces of Ukraine. The GRU's cyber units reportedly attempted to launch extensive cyber attacks to gain control over Android devices of Ukrainian military personnel, which were used for planning and performing combat missions. The SBU identified and neutralised various malware instances deployed by Russian cyber intelligence, particularly the Sandworm hacker group from military unit 74455. The attack exploited captured battlefield devices to gain access to local networks using stolen keys and employed Android Debug Bridge (adb) for installing malicious files on compromised devices. | Russian threat actors | |
| Lazarus hackers exploit Zoho's ManageEngine vulnerability North Korean state-backed hacker group Lazarus has been exploiting a critical vulnerability in Zoho's ManageEngine ServiceDesk (CVE-2022-47966) to compromise an internet backbone infrastructure provider and healthcare organisations in the US and UK. The attacks, which began earlier this year, involve deploying the QuiteRAT malware and a new remote access trojan (RAT) called CollectionRAT, with Lazarus displaying evolving tactics such as the incorporation of the Microsoft Foundation Class framework to evade detection and enhance its capabilities. | North Korean threat actor | |
| Cyberespionage group targets foreign embassies in Belarus with local ISP assistance According to cybersecurity company ESET, a recently discovered cyberespionage group named MustachedBouncer has been targeting foreign embassies in Belarus, often collaborating with local internet service providers (ISPs). The group, operating since 2014, has compromised embassy staff from various countries, and it employs tactics such as lawful interception systems, including possible use of Russian SORM network interception technology, and custom malware called Disco. ESET suggests that the group cooperates closely with a suspected Belarusian pro-Russian cyberespionage effort named Winter Vivern. | Unattributed threat actors |
Cybercrime
| Increase in ransomware attacks on Finnish organisations linked to geopolitical factors According to Finland’s National Cyber Security Centre (NCSC-FI), ransomware attacks on Finnish organisations have quadrupled since Finland applied to join NATO, which the NCSC-FI deputy director general believes could be linked to geopolitical factors. While there has been an increase in cyber incidents, particularly ransomware cases, there hasn't been any publicly visible disruption, thanks in part to the preparedness of Finnish organisations. | Multiple sectors | |
| Faust ransomware compromised two Danish hosting providers, affecting all of their customers data On August 18, the Faust ransomware operation targeted two Danish hosting providers (CloudNordic and Azero). Both providers stated that the cybercriminals gained access to the central administration system and the backup systems before deploying the ransomware, encrypting all servers disks, as well as the primary and secondary backup systems. The providers immediately informed their customers that all of their data is lost. | Web hosting | |
| German Federal Bar Association hit by ransomware The German Federal Bar (BRAK) Association discovered on August 2 that it's Brussels' office was hit by a ransomware attack. BRAK is an umbrella organisation overseeing 28 regional bars across Germany and representing about 166.000 lawyers nationally and internationally.
