The US Treasury imposed sanctions on Aeza Group, a Russian bulletproof hosting provider, and four associated individuals for facilitating ransomware and cybercriminal activities. This marks the second instance in 2023 where bulletproof hosting providers faced sanctions. Aeza Group provided infrastructure to notable ransomware gangs like BianLian and operations such as Meduza and Lumma. BianLian has shifted towards data exfiltration-based extortion methods and has targeted critical infrastructure in the US. The NCA helped coordinate Aeza International’s designation on the sanctions list while some of Aeza Group's leaders were also personally sanctioned.
