Cloudflare defends against largest ever DDOS attack

February 21, 2023

Cloudflare has disclosed that it managed to protect its network and its customers from the largest DDoS attack in history.

According to Cloudflare, the attacks originated from over 30,000 IP addresses and targeted businesses such as gaming providers, hosting providers, cloud computing platforms, and cryptocurrency companies.

At its peak, the attack exceeded 71 million requests per second (rps), classifying it as a “hyper-volumetric” attack, according to Cloudflare. The cyberattack broke Google’s previous record for DDoS attack volume, which was 46 million rps in June 2022.

A flood of virtual private servers (VPSs)/virtual machines (VMs) with high throughput and computation power was used in the attack. At its peak, each node generated around 4-5 thousand requests per second (rps). These attacks were widely dispersed, with over 30,000 different IP addresses originating at a rate of up to 15,000 per second.

The attacks were HTTP/2-based and targeted Cloudflare-protected websites. They came from over 30,000 different IP addresses. A popular gaming provider, cryptocurrency companies, hosting providers, and cloud computing platforms were among the websites targeted. The attacks originated from a variety of cloud providers, and we have been collaborating with them to combat the botnet.

“Over the past year, we’ve seen more attacks originate from cloud computing providers, Cloudflare researchers wrote in a report, adding that the network traffic used in the attacks over the weekend came from “numerous cloud providers.”
