Cloudflare has recorded a DDoS attack twice the size of the previous record attack
Cloudflare has had to document a new milestone in cyber attacks: a distributed denial-of-service (DDoS) attack with a speed of 22.2 terabits per second and 10.6 billion packets per second. According to the company, this is the largest attack ever recorded, and this while record attacks are occurring more frequently this year.
One Million 4k Streams Simultaneously
The attack lasted 40 seconds and the data traffic was enormous, equivalent to simultaneously streaming one million 4K videos. The packet density was comparable to refreshing 1.3 web pages per second by every person on Earth, putting severe strain on traditional firewalls and routers.
This year alone, Cloudflare has recorded three record-breaking DDoS attacks. The first occurred in June with a speed of 17.3 Tb/s.
Rise of the AISURU Botnet
While Cloudflare didn’t provide details themselves, researchers from Qi’anxin attribute an earlier record attack of 11.5 Tb/s to the AISURU botnet. This network comprises more than 300,000 infected devices, including routers, IP cameras, and DVR systems. The infection wave began in April following the hack of a Totolink firmware update server, reports Bleeping Computer.
With this new attack, Cloudflare warns again that 2025 is becoming a record year for DDoS attacks.
