ECHO: Replacing the Compliance Proxy with Response Harmfulness in Optimization-Based Jailbreak Attack
ECHO replaces the token-level compliance proxy used in jailbreak optimisation with a direct harmfulness metric, potentially making adversarial safety evaluations of LLMs more realistic and harder to game.

arXiv:2610.23030v1 Announce Type: new Abstract: Despite extensive safety alignment, large language models remain vulnerable to jailbreak attacks. Existing optimization-based attacks share a single objective: maximize a token-level proxy of victim compliance---such as the likelihood of an affirmative prefix---computed on the prompt rather than the decoded reply. This proxy cannot distinguish a cautious hedge from a fully actionable harmful answer, leaving the search blind to what the model actua
Editorial Analysis
Enterprises relying on safety-alignment certifications for LLMs should note that current jailbreak benchmarks may understate real-world risk if they optimise for compliance proxies rather than actual harm.
Ask your LLM vendors whether their safety evaluations use compliance proxies or direct harmfulness measures, and factor the answer into procurement risk assessments.
