Multinational Operation PowerOFF Seizes 53 DDoS-for-Hire Domains, Makes 4 Arrests Across 21 Countries

Law enforcement from 21 countries led by Europol seized 53 DDoS-for-hire domains, executed 25 search warrants, obtained over 3 million user account records, and arrested 4 individuals in the latest action week of Operation PowerOFF, announced April 16. Over 75,000 warning letters were sent to identified users of booter services. The US, UK, Australia, Germany, and Japan participated alongside European and Baltic partners. Services targeted included low-cost stressor platforms that enabled non-technical users to launch denial-of-service attacks. The operation continues an ongoing campaign against the criminal DDoS ecosystem that supports state-linked proxies and financially motivated actors alike.

Analysis
The 21-country PowerOFF tempo, anchored by Europol's own release and corroborated without divergence by CyberScoop, is crystallizing as the template for dismantling below-threshold cybercrime infrastructure that state actors rent without attribution risk. The 3 million account records extracted from seized databases hand FBI, NCA, and BKA analytic teams a rare attribution corpus that very likely seeds parallel counterintelligence leads against nation-state booter rental within the next 60 days. The four arrests understate the actual pressure vector: stripping the customer-trust layer from booter markets is likely to raise effective cost per DDoS campaign for pro-Russian hacktivist fronts targeting Baltic and Polish infrastructure within the coming weeks. The ecosystem has, however, previously reconstituted within months of comparable seizure actions, and without follow-on treasury designations against operators and hosting providers, the disruption may prove transitory rather than structural.
