Dutch authorities arrested a 33-year-old man at Schiphol Airport, believed to be the mastermind behind the AVCheck malware platform. This site, shut down in May 2025, allowed cybercriminals to test their malware against various antivirus systems. The arrest followed an international investigation linked to the platform's takedown.

An international law enforcement operation has successfully taken down AVCheck, a counter antivirus service used by cybercriminals to test malware evasion against commercial antivirus software. The takedown is part of Operation Endgame, which aims to disrupt organized cybercrime by targeting services that help criminals refine their malware for maximum effectiveness. Evidence links AVCheck's administrators to other crypting services that further support cybercriminal activities.
