Microsoft says it mitigated a 2.4 Tbps DDoS attack, one of the largest DDoS attacks ever recorded

Microsoft says that it mitigated a 2.4 Tbps distributed-denial-of-service (DDoS) attack on its Azure network in August. DDoS attacks are usually a tool used to take down websites or systems, often flooding them with traffic that the server can’t handle. This was significantly higher than an attack on the Azure network in 2020 that reached peak traffic speeds of 1 Tbps. This 2.4 Tbps attack is higher than any network volumetric event previously detected on Azure.
Microsoft says that the attack lasted a little bit longer than 10 minutes with very short-lived bursts, each ramping up in seconds to terabit volumes. In total, there were three peaks; the first at 2.4 Tbps, the second at 0.55 Tbps, and the third at 1.7 Tbps. Thanks to Azure’s DDoS protection platform (built on distributed detection and mitigation platforms), customers were completely unaffected. Furthermore, Microsoft says that its DDoS protection platform can withstand the brunt of tens of terabits of traffic. This attack …
