Cyber security company Cloudflare has detected and repelled dozens of DDoS attacks. Most attacks peaked at between 50 and 70 million requests per second (rps), with the largest attack exceeding 71 million rps.
A few weeks ago, strangers attacked Cloudflare's network. However, the CDN provider was able to fend off the DDoS attack without further failures and redirected the requests to its large scrubbing center. These can easily record and analyze the attacks and sort out and block the malicious requests. However, normal requests to a page are forwarded.
DDoS as a default weapon
Although DDoS is one of the oldest types of attacks on the Internet, it remains popular with cyber gangsters. But the attack now reported was special: This is the largest reported HTTP DDoS attack ever at 71 million requests per second (rps) and is more than 35% above the previous record of 46 million rps set in June 2022.
The attacks were based on HTTP/2 and targeted websites protected by Cloudflare. They assumed over 30.000 IP addresses. The websites attacked include a popular game provider, cryptocurrency companies, hosting providers and cloud computing platforms. The attacks came from numerous cloud providers that Cloudflare works with.
Attack from 30.000 IP address
Over the past year, the company noticed that more attacks were coming from cloud computing providers. For this purpose, a free botnet threat feed is made available to service providers who have their own autonomous system. Service providers operating their own IP space can now queue for early access.
