Internet infrastructure company Cloudflare said it recently blocked the largest recorded volumetric distributed denial-of-service (DDoS) attack, which peaked at 11.5 terabits per second (Tbps). In volumetric DDoS attacks, attackers overwhelm the target with massive amounts of data, consuming the bandwidth or exhausting system resources, leaving legitimate users with no access to the targeted servers and services. Cloudflare’s defenses have been working overtime. Over the past few weeks, we’ve autonomously blocked hundreds of hyper-volumetric DDoS attacks, with the largest reaching peaks of 5.1 Bpps and 11.5 Tbps, the company said in a Tuesday tweet. While Cloudflare initially stated that the 11.5 Tbps UDP flood attack lasted approximately 35 seconds and primarily originated from Google Cloud, the company later issued a correction, saying that the attack in fact came from a combination of several IoT and cloud providers. Our abuse defenses detected the attack, and we followed proper protocol in customer notification and response. Initial reports suggesting that the majority of traffic came from Google Cloud are not accurate, a Google Cloud spokesperson also told BleepingComputer. This comes two months after Cloudflare announced another record-breaking 7.3 Tbps DDoS attack targeting an unnamed hosting provider in June. The previous record was of 3.8 Tbps and two billion packets per second (pps) in an attack that Cloudflare also blocked in October 2024. Microsoft also mitigated a 3.47 Tbps volumetric DDoS attack in January 2022, when the attackers targeted an Azure customer from Asia. Another massive DDoS attack took down and disrupted multiple Microsoft 365 and Azure services worldwide in July 2024.
