2025 Q4 DDoS Report: Record 31.4 Tbps Attack and Botnet
🛡️ Cloudflare's 24th Quarterly DDoS Threat Report documents a record-setting 2025 capped by a 31.4 Tbps attack and a late-December campaign from the Aisuru-Kimwolf botnet. The firm observed a 121% year-over-year surge in DDoS activity, averaging 5,376 mitigations per hour and a tripling of network-layer assaults to 34.4 million. Hyper-volumetric HTTP floods—largely from infected Android TVs—peaked above 200 Mrps and targeted telcos, gaming, and AI providers, while Cloudflare's autonomous defenses automatically detected and mitigated these incidents.
