Cloudflare Stops New World's Largest DDoS Attack Over Labor Day Weekend

An anonymous reader quotes a report from ZDNet: Over the Labor Day weekend, Cloudflare says it successfully stopped a record-breaking distributed denial-of-service (DDoS) attack that peaked at 11.5 terabits per second (Tbps). This came only a few months after Cloudflare blocked a then all-time high DDoS attack of 7.3 Tbps. This latest attack was almost 60% larger.

According to Cloudflare, the assault was the result of a hyper-volumetric User Datagram Protocol (UDP) flood attack that lasted about 35 seconds. During that just more than half-minute attack, it delivered over 5.1 billion packets per second. This attack, Cloudflare reported, came from a combination of several IoT and cloud providers. Although compromised accounts on Google Cloud were a major source, the bulk of the attack originated from other sources.

The specific target of this attack has not been publicly disclosed, but we can be sure the intent was to overwhelm the victim's network and render online services inoperative. Cloudflare says its globally distributed, fully autonomous DDoS mitigation network detected and neutralized the threat in real time, without notable impact on customer services or requiring manual intervention. This operation highlights both the rising sophistication of attack methods and the resilience of modern internet infrastructure defenses, especially Cloudflare's use of real-time packet analysis, fingerprinting, and rapid threat intelligence sharing across its network.
