Racing and Fuzzing HTTP/3: Open-sourcing QuicDraw(H3)
This blog post provides a dive into HTTP/3’s evolution for security engineers, an overview of our research journey, and what led us to develop the open-source tool QuicDraw, which can be used for fuzzing and racing HTTP/3 applications. QuicDraw implements “Quic-Fin-Sync” our implementation of the last-byte-sync with the single packet attack on HTTP/3. We conclude by evaluating QuicDraw’s performance against a real-world target and comparing its results to other tools.
