Europol emails 75,000 alleged DDoS buyers
Europol led a coordinated global law enforcement action, Operation PowerOFF, targeting distributed denial-of-service (DDoS) for-hire services. Authorities seized servers and data, enabling them to identify and send warning emails and letters to more than 75,000 suspected users of those services. The operation resulted in four arrests, the takedown of 53 domains, and execution of 24 search warrants. The report notes DDoS-for-hire services lower the barrier to launching disruptive attacks, and references Cloudflare’s mitigation of a recent peak DDoS of 29.7 Tbps as context for the continuing threat.
Coordinated takedown and mass identification of DDoS-for-hire users reduces risks to web availability and ad inventory; domain takedowns and arrests have moderate industry impact for publishers, CDNs and ad platforms.

Global Crackdown Dismantles Massive Router Botnet Operation
A global law enforcement coalition dismantled SocksEscort, a paid proxy service built on a botnet of hacked home and small-business routers. The U.S. Department of Justice said SocksEscort’s infrastructure was used to commit widespread crimes — including account takeovers, fraudulent unemployment claims, ransomware facilitation, DDoS attacks, and distribution of CSAM — that cost Americans millions. Europol reported the botnet had compromised more than 369,000 routers and IoT devices across 163 countries and that infected devices were disconnected from the service. Cybersecurity firm Black Lotus Labs, which tracked the operation and assisted law enforcement, said the botnet was powered by AVRecon malware and had been composed of roughly 280,000 routers since January. The SocksEscort site was seized as part of the operation.
Microsoft and BKA Disable 200 Hacker Servers Worldwide
Microsoft, Europol and the German Bundeskriminalamt (BKA) carried out an international operation that disabled more than 200 command-and-control servers and severed criminal control over over 18,000 identified victim computers. The takedown targeted two widely used malware families, Amadey and StealC. Investigators used artificial intelligence to accelerate reverse-engineering of complex code and Microsoft's legal team invoked the U.S. RICO statute to treat multiple actors as a single conspiracy, enabling a coordinated, large-scale attack on the shared infrastructure. German authorities and Europol’s EC3 participated in the effort, which builds on previous international actions such as Operation Endgame from May 2024.
Authorities Take Down Two Major DDoS Botnets
German and North American law-enforcement agencies disrupted the infrastructure of two of the world’s largest botnets — Aisuru and Kimwolf — which were used to launch large-scale distributed-denial-of-service (DDoS) attacks. The Bundeskriminalamt (BKA) and Nordrhein‑Westfalen’s ZAC, together with Canadian and U.S. authorities, disabled the globally distributed technical infrastructure but did not make arrests. Authorities identified two suspected administrators and seized extensive evidence during searches in Germany and Canada, including data drives and five-figure sums in cryptocurrency. Aisuru is linked to massive IoT-based attacks (including an attributed 31.4 Tbps DDoS mitigated by Cloudflare); Kimwolf is closely related and focused more on Android and consumer devices such as TV boxes. The primary targets of past DDoS incidents have included public services and apps, for example Germany’s Deutsche Bahn and its DB Navigator app.
