Cloudflare successfully mitigated a record-breaking 5.6 Tbps Distributed Denial of Service (DDoS) attack on October 29, 2024. The attack, launched by a Mirai-variant botnet, targeted an internet service provider (ISP) in East Asia. The botnet comprised of 13,000 compromised IoT devices flooding the target with malicious data, which aimed to cripple the ISP’s operations.

The attack lasted only 80 seconds, but Cloudflare's autonomous defence systems promptly identified and mitigated the anomalous traffic without human intervention, intercepting and neutralizing the malicious data at Cloudflare's edge nodes. Each IP address within the botnet generated an average traffic of approximately 4 Gbps. The successful defense highlights the escalating sophistication and scale of DDoS threats, with hyper-volumetric attacks exceeding 1 Tbps dramatically increasing. This incident underscores the importance of robust DDoS mitigation strategies and the need for continuous evolution in network security.
