Cloudflare Mitigates Record-Breaking 5.6 Tbps DDoS Attack

The unprecedented attack, targeting an East Asian ISP, was autonomously neutralized in 80 seconds without human intervention or service disruption.

The October 29 attack, launched by a Mirai-based botnet of 13,000 devices, peaked at 5.6 terabits per second, making it the largest DDoS attack ever recorded.
Cloudflare's automated defense systems detected and mitigated the attack with no alerts triggered or performance degradation reported.
Hypervolumetric DDoS attacks, characterized by their massive scale and short duration, have surged, with attacks exceeding 1 Tbps increasing by 1,885% in Q4 2024 compared to Q3.
Ransom DDoS attacks, where attackers demand payment to prevent or stop disruptions, also saw a significant rise, particularly during high-traffic periods like holidays.
China, the Philippines, and Taiwan were among the most targeted regions in late 2024, with telecommunications and internet service providers being the primary industries affected.
