Crypto news, via a report from TRM Labs: the U.S. Department of the Treasury’s OFAC has sanctioned FirstVPN and its administrator Dmytro Rashevskyi, as well as the Belarus-based “cryptomixer” service provider Yevgeniy Silayev, accusing them of providing anonymous networking and malware obfuscation tools for ransomware attacks targeting U.S. businesses, hospitals, and government agencies. This action is not aimed at any specific ransomware gang, but directly at its infrastructure supplier. OFAC also listed 20 related crypto addresses, involving BTC, ETH, TRX, LTC, DOGE, DASH, ZEC, and SOL. On-chain tracking by TRM shows that ransomware groups such as Anubis and Qilin had directly paid FirstVPN for service fees.
