New DDoS Attack is Record Breaking: HTTP/2 Rapid Reset Zero-Day Reported by Google, AWS & Cloudflare
Find out what security teams should do now, and hear what Cloudflare's CEO has to say about this DDoS. Google, AWS and Cloudflare have reported the exploitation of a zero-day vulnerability named HTTP/2 Rapid Reset and tracked as CVE-2023-44487, which is currently used in the wild to run the largest Distributed Denial of Service attack campaigns ever seen. The HTTP/2 Rapid Reset attack works by leveraging HTTP/2's stream cancellation feature: The attacker sends a request and cancels it immediately.
The method relies on stream multiplexing, a feature of the HTTP/2 protocol that allows multiple HTTP requests to be sent to a server on a single TCP connection. A feature of the protocol's streaming capability is the ability to send a request and soon after cancel that request, an action known as resetting the request's stream.
