Breaking LLMs With Fuzzing: Inside GPTFuzz’s Automated Jailbreak Machine

Software security has long relied on a technique called fuzzing, i.e. bombarding a program with malformed, unexpected, or mutated inputs until something breaks. Tools like AFL (American Fuzzy Lop) have uncovered thousands of real-world vulnerabilities this way. At Keysight, fuzzing has been a core part of security testing for years, with extensive expertise in protocol fuzzing , dedicated fuzzing solutions , and research blogs covering modern attack techniques. As AI systems become the new softw
