Four Russian nationals linked to the 8Base ransomware group have been arrested in Phuket, Thailand, as part of a multinational law enforcement operation involving 14 agencies. The suspects, comprising two men and two women, are accused of orchestrating ransomware attacks targeting 17 Swiss companies between April 2023 and October 2024, stealing $16 million worth of Bitcoin from over 1,000 victims worldwide. The group used the Phobos ransomware variant to encrypt data and extort payments, threatening to leak sensitive information if ransoms were not paid. The operation, named 'Phobos Aetor,' led to the seizure of digital infrastructure, including laptops, smartphones, and digital wallets, and the takedown of the group's data leak site. Europol confirmed the arrests and highlighted the operation's complexity, which also involved dismantling 27 servers linked to the criminal network. Additionally, the U.S. Justice Department has charged Roman Berezhnoy and Egor Nikolaevich Glebov with multiple offenses, including wire fraud and computer fraud, for their roles in the attacks. This marks another significant step in combating ransomware operations globally.
