DDoS, Bulletproof Hosting, and Health data Hacks: January 10, 2024 News

Record Surge in DDoS Attacks, Driven by Advanced Exploits and AI Tools

Distributed denial of service (DDoS) attacks reached a record high in 2023, with a notable increase in the fourth quarter, as reported by Cloudflare. A key factor in this surge was the exploitation of the HTTP/2 Rapid Reset zero-day vulnerability. Cloudflare experienced peak mitigation of around 201 million requests per second during these attacks. The ease of launching massive DDoS attacks has grown; in 2024, it only requires 5,000 to 20,000 virtual machines to exceed 100 million requests per second, a significant reduction in resources compared to previous years. Additionally, generative AI tools have been used to refine attack scripts. Retail, shipment, and public relations sites were prime targets, particularly during the holiday season. Cloudflare also noted a shift in attack methods, with a decrease in HTTP DDoS attacks but an 85% increase in network-layer attacks.

Cloudflare has purpose-built technology to mitigate exploiting the HTTP/2 vulnerability.
