DUTCH COPS CUFF ALLEGED AVCHECK MALWARE KINGPIN IN AMSTERDAM

Summary from the TLDR InfoSec newsletter

Dutch authorities have arrested a 33-year-old Dutch suspect at Schiphol Airport, accusing him and two linked companies of running AVCheck, a major counter-antivirus platform that lets criminals test and fine-tune malware against multiple security products. AVCheck, dismantled in May 2025 during Operation Endgame, allegedly helped attackers perfect campaigns by identifying which targets and defenses were easiest to evade.
