U.S. Treasury Sanctions VPN Provider and Cryptor Seller Behind Billions in Ransomware Losses

The U.S. Treasury (OFAC) designated VPN provider 1VPNS, its administrator Dmytro Rashevskyi, and cryptor seller Yegeniy Silayev for supplying infrastructure and obfuscation tools to ransomware groups that have caused billions in losses to U.S. businesses and critical infrastructure; the action follows a May 2026 law-enforcement takedown of 1VPNS servers and is coordinated with UK and European partners.
