Should you pay the ransom?
1. UK Electoral Commission breach exposes personal data of 40 million voters
The UK Electoral Commission has disclosed a data breach that enabled threat actors to access personal data of 40 million voters. The intruders' identities are presently unknown, and reports say they were able to access the Commission's control systems, hosting email and copies of the electoral registers. The registers had the name and addresses of voters registered between 2014 and 2022. While the breach did not jeopardize the registration or electoral process, the Commission urges voters to stay vigilant for potential data misuse.
2. U.S. Cyber Board to investigate Microsoft for its role in China-backed email breach
The U.S. Cyber Safety Review Board (CSRB) recently stated that it will probe risks associated with cloud computing. This will include an investigation of Microsoft Corp's involvement in a government email system breach, which is believed to be orchestrated by Chinese cybercriminals. Following this breach, Oregon Senator Ron Wyden urged action against Microsoft. This cyberattack allegedly granted hackers significant access to Microsoft's cloud-based email, impacting communications of key U.S. figures, including Commerce Secretary Gina Raimondo.
3. Knight ransomware found in an ongoing TripAdvisor spam campaign
BleepingComputer reports that malicious actors are distributing the Knight ransomware through spam campaigns cleverly disguised as TripAdvisor complaints. Knight is not entirely new; it's a rebranded version of the Cyclop Ransomware-as-a-Service, updated in July 2023. The ransomware tricks users into downloading and activating it, after which it encrypts their files and demands a Bitcoin ransom of $5,000. Experts advise against paying due to the high risk of not receiving a decryption tool.
4. Xiaomi’s MIUI blocks Telegram, which flags it as dangerous in China
Asian smartphone maker Xiaomi has halted Telegram installations on its MIUI devices. MIUI's 2022 update introduced a feature that blocks perceived malicious apps, with Telegram now on that list. Critics suggest this might be Xiaomi's alliance with the Chinese Community Party to surveil and censor user activities. The recent restriction of Telegram, branded as "dangerous," underscores China's growing ambition to oversee digital communications.
5. Cyber espionage group leveraging AiTM techniques to spy on diplomats
Belarus-affiliated APT "MoustachedBouncer" reportedly spied on staff across four embassies in Belarus, possibly exploiting the local ISP. ESET senior malware researcher, Matthieu Faou, revealed this espionage activity dating from 2017 to 2022 during a Black Hat presentation. The APT likely leveraged lawful interception technology, common in Belarus and Russia, at the ISP level. The group's tactics include redirecting users to fake Windows Update pages with malware capable of extensive data exfiltration. Faou emphasized the importance of VPNs for secure communications in such nations.
