Meduza is an infostealer malware operation associated with credential theft and data exfiltration. It has been identified as a customer of Russian bulletproof hosting services, including infrastructure linked to Aeza Group. Meduza has been tied to activity targeting the United States, including attacks against the U.S. defense industrial base and technology companies. The operation is part of the broader cybercrime ecosystem that relies on abuse-resistant hosting to sustain malware delivery, command-and-control, and stolen-data handling. Based on the available facts, Meduza is best characterized as a financially motivated cybercriminal threat rather than a state actor.
