Black Hat USA 2021: Port Swigger's latest research to be unveiled

Summary: PortSwigger director of research James Kettle will present "HTTP/2: The Sequel is Always Worse" at Black Hat USA 2021, held July 31 to August 5, following his earlier "HTTP Desync Attacks" talk that kicked off a wave of request smuggling. The talk covers HTTP/2-exclusive desync attacks with case studies against servers including Amazon's Application Load Balancer, WAFs, CDNs and bespoke big-tech stacks, demonstrated through hijacking thick clients, poisoning caches and stealing plaintext passwords to net multiple max-bounties.

What's compelling: The flaws described reach infrastructure many organizations treat as trusted plumbing - Amazon's Application Load Balancer, WAFs and CDNs - and the stated payoff is plaintext password theft and multiple max-bounty awards.
