Bigger and badder: how DDoS attack sizes have evolved over the last decade

Cloudflare analyzes a decade of DDoS activity, finding exponential growth in attack scale across requests per second, packets per second, and bits per second, with peaks reaching 201 Mrps, 2,100 Mpps, and 5.6 Tbps by 2024. The report highlights a shift from IoT-based botnets to more powerful VM-driven botnets and references notable techniques and events such as HTTP/2 Rapid Reset, while outlining Cloudflare’s automated, layered, Anycast-enabled defenses and unmetered DDoS mitigation.
