GoKawiilPortSwigger's James Kettle builds AI tool 'HTTP Terminator' that finds new smuggling attacks
At Black Hat USA 2026, PortSwigger research director James Kettle unveiled an open source AI-driven tool called HTTP Terminator, designed to test whether AI could invent original hacking techniques rather than just find known bugs. The tool autonomously produced new HTTP desync, or request smuggling, attacks and used them to breach real enterprise sites, including several belonging to financial services firms.
