I Fuzzed 12 LLMs With 19 Payloads — Here What Broke
A security researcher tested 12 large language models using a fuzzer tool and found that many still have vulnerabilities. The tests revealed that direct injection, role-play bypasses, and encoding evasion techniques could still compromise several models, with multi-turn degradation proving particularly effective. The researcher recommends that AI product teams implement rigorous fuzzing, monitor conversations for guardrail decay, and test specific encoding attacks to improve the security of their AI agents.
