Record-breaking DDoS attack equivalent to 1 million 4K streams at once

Cloudflare, a leading content delivery network, recently recorded the largest distributed denial-of-service (DDoS) attack ever measured, reaching a peak of 22.2 terabits per second (TB/s) of network activity. This attack surpassed the previous record of 11.5 TB/s set just three weeks ago. The DDoS attack lasted for 40 seconds and was equivalent to streaming 1 million 4K videos simultaneously. The packet rate of 10.6 billion packets per second (Bpps) translates to roughly 1.3 web page refreshes per second from every person on the planet, making it extremely challenging for firewalls, routers, and load balancers to process the requests. While the identity of the perpetrators is still unknown, experts believe the previous record-breaking DDoS attack was carried out by a botnet called Aisuru. The scale and intensity of these attacks highlight the growing threat of DDoS attacks and the importance of robust cybersecurity measures to protect against such large-scale disruptions.
