Cloudflare announced that it had successfully protected one of its customers from one of the most powerful DDoS attacks in history.According to the service provider, the undisclosed cryptocurrency platform was targeted by a botnet of about 6000 \"zombie computers\" spread across 112 countries.The botnet ended up generating 15.3 million requests per second.Although this is still less than the highest recorded figure, set at 17.2 million requests per second, the fact that the DDoS attack took place over HTTPS probably made its complexity higher than the record attack because of the higher computational load of secure HTTP.The attack lasted 15 seconds.DDoS attacks aim to flood the network with requests and data packets to overwhelm and paralyze it.The attack also demonstrates the ingenuity of the attackers as they come from cloud-based ISPs, as the attackers use more sophisticated and powerful network equipment than what ISPs typically offer.According to Cloudflare, the botnet appears to have mostly compromised systems with Java applications that were still vulnerable to the recently discovered CVE-2022-21449 vulnerability.
