DDoS attacks over 1 Tbps surged fivefold in the second quarter

Cloudflare says it mitigated more than 800 network-layer distributed denial-of-service (DDoS) attacks exceeding 1 Tbps in the second quarter of the year.

Compared with the first quarter, when the company recorded just 130 attacks above 1 Tbps, the latest figure represents a more than fivefold increase.

Cloudflare is a major web infrastructure and security firm that provides CDN, DNS, reverse-proxy, and DDoS protection services to customers worldwide, protecting roughly 20% of the web.

The company's services sit between DDoS botnets and their intended targets, allowing it to observe and absorb attacks at enormous scale.

Recently, the company mitigated a record-breaking attack that peaked at 31.4 Tbps and 200 million requests per second, launched by the Aisuru/Kimwolf botnet.

In a new report shared with BleepingComputer and presented earlier today at the Black Hat security conference, Cloudflare says that in the first half of the year it mitigated 23.2 million network-layer DDoS attacks and 29.64 trillion malicious HTTP requests.
