Meet HTTP Terminator, a new AI system that has identified hundreds of websites vulnerable to HTTP request smuggling, hacked them live at scale, and even identified a “genuinely new class” of vulnerability, dubbed “shared-parser confusion.”
But it didn’t do it alone; it was guided by a human the entire time, which may be the most interesting finding of all.
A researcher from security company PortSwigger used his own processes to design and build the AI, HTTP Terminator, posed narrow, high-value questions, ruled out weak answers, applied anomaly-detection logic, used deterministic code to restrict agent behavior, and applied findings to subsequent ‘cascade’ research.
