Operation Endgame Disrupts Rhadamanthys, VenomRAT, and Elysium Malware Operations

International law enforcement agencies, coordinated by Europol and Eurojust, executed a major crackdown on the infrastructures supporting the Rhadamanthys infostealer, VenomRAT remote access trojan, and the Elysium botnet. The operation, part of the ongoing Operation Endgame, resulted in the takedown of over 1,025 servers and the seizure of 20 domains used to control and distribute these malware families. Authorities also arrested the main suspect behind VenomRAT in Greece, and the dismantled infrastructure included hundreds of thousands of infected computers and millions of stolen credentials, with many victims unaware of the compromise. The operation involved law enforcement from at least nine countries and was supported by numerous private sector partners, including cybersecurity firms and threat intelligence organizations.

Rhadamanthys, a modular information stealer sold as malware-as-a-service, and VenomRAT, a commodity RAT favored by threat actors like TA558, were both widely distributed through email campaigns, malvertising, and other vectors. The Elysium botnet, less well-documented, was also linked to these operations, potentially serving as a proxy network for criminal activity. The disruption has caused significant operational issues for cybercriminals, with many reporting loss of access to their command-and-control panels and servers. Authorities have advised potential victims to check if their systems were compromised and to take remediation steps, as the takedown is expected to have a substantial impact on the cybercrime ecosystem.
