Cloudflare revealed on Tuesday that it successfully detected and blocked a distributed denial-of-service (DDoS) attack reaching speeds of up to 5.6 terabits per second (Tbps), marking the largest attack ever recorded. This attack occurred on October 29, 2024, targeting an Internet Service Provider (ISP) in East Asia. The assault utilized the UDP protocol and was launched by the Mirai botnet, which harnessed over 13,000 IoT devices.
Cloudflare reported that this record-breaking attack surpassed another DDoS attack recorded earlier in the same month, which reached 3.8 Tbps. The attack lasted only 80 seconds, with an average of 5,500 source IP addresses per second, and each device contributed approximately 1 Gbps of traffic. Cloudflare’s DDoS protection capabilities in 2024 have significantly improved, blocking over 21.3 million attacks, a 53% increase compared to 2023. Attacks exceeding 1 Tbps also surged by a staggering 1,885% within the year.
The rise in DDoS attacks highlights the growing focus of Mirai botnets on exploiting IoT device vulnerabilities. Indonesia, Hong Kong, and Singapore were identified as the primary sources of these attacks, while China, the Philippines, and Taiwan were the most heavily impacted countries. Industries that faced the brunt of the attacks included telecommunications, internet services, and gambling. This incident underscores the critical need to enhance IoT security to reduce the risk of devices becoming victims or tools for future DDoS attacks.
