The international law enforcement operation known as Operation Endgame has successfully disrupted the infrastructure of the notorious infostealer malware strains StealC and Amadey. Coordinated by Europol and involving Germany’s Federal Criminal Police Office, alongside an array of industry partners such as Microsoft, IBM X-Force, and BitSight, the operation successfully seized around 50 domains and nearly 200 command-and-control servers globally.

Following the takedown, valuable recovery steps were taken, including freezing €41m in criminal crypto assets and securing 27 million stolen login credentials, illustrating a significant move towards dismantling organized cybercrime networks globally.
