Full Summary
Cloudflare's DDoS Threat Report for Q3 2026 highlights a 208% surge in short-burst attacks lasting under 10 minutes and under 1 Gbps, contrasting with a 69% drop in hyper-volumetric attacks exceeding 1 Tbps. This decline is attributed to law enforcement actions against major IoT botnets earlier in the year.
Attackers have shifted tactics, moving away from CLDAP floods, which fell by 99.5%, towards DNS amplification attacks, which rose by 215%. The report also notes a broadening of attack targets across various industries and regions, with the U.S. becoming the most-attacked country again.
Cloudflare mitigated over 18 million DDoS attacks in this quarter alone, showcasing the ongoing threat landscape and the need for robust defenses.
