The Aisuru botnet has established a new benchmark in distributed denial-of-service attacks (DDoS), reaching 31.4 terabits per second in a campaign that Cloudflare detected and stopped in December 2025. The attack exceeded the botnet’s previous record of 29.7 Terabits per second (Tbps) from just three months earlier, making it the largest publicly disclosed DDoS attack to date.
