Cloudflare's 2025 Q1 DDoS report documents a dramatic surge in DDoS activity—21.3M attacks in 2024 and 20.5M in Q1 2025—with a sharp rise in network-layer and hyper-volumetric attacks (700+ events >1 Tbps and daily high-volume events); attackers used multi-vector tactics (SYN floods, Mirai, SSDP) and emerging CLDAP and ESP reflection/amplification techniques, targeting Cloudflare infrastructure and gaming servers, and included a brief 5.8 Tbps peak attack.
