German authorities, in collaboration with the United States and Canada, have conducted a joint operation to dismantle several of the world's largest botnet networks, according to reports from German officials. The operation targeted botnets including Aisuru and Kimwolf, which were reportedly involved in massive distributed denial-of-service (DDoS) attacks reaching record levels of 30 terabits per second.
The Aisuru botnet consisted of a network with millions of compromised online devices such as routers and web cameras, according to a statement from police and prosecutors. The associated Kimwolf botnet also encompassed millions of infected devices. These botnets allegedly launched DDoS attacks targeting victims worldwide.
The U.S. Department of Justice confirmed in a press release that infrastructure behind four botnets had been taken down, specifically naming Aisuru, Kimwolf, Jackskid, and Mossad. The operation represents a significant international cybersecurity effort against networks that had exploited approximately three million connected devices for their attacks.
