This is the largest publicly recorded thwarted DDoS to date. The assault consisted of a “month-long” barrage in September 2024 of more than 100 hyper-volumetric DDoS attacks flooding the network infrastructure with garbage data.
The previous record-breaking volumetric DDoS attack was reported by Microsoft in November 2021, peaking at 3.47 Tbps with a packet rate of 340 million Pps (Packets per second). The largest attack previously seen by Cloudflare peaked at 2.6 Tbps.
According to Cloudflare, the infected devices were spread across the globe but many of them were located in Russia, Vietnam, the US, Brazil and Spain
