europol-coordinated operation endgame disrupted the stealc malware-as-a-service ecosystem by taking down 66 domains and 296 servers, seizing 25.6 million credentials stolen from 385,000 compromised systems. law enforcement exploited a vulnerability in stealc's own command-and-control panel to access stolen data. this is structurally notable because the operation turned the adversary's infrastructure against itself — a technique that yields intelligence beyond takedown and signals maturation of law enforcement offensive capability in this domain.
