Mechanistic interpretability tools create a dual-use attack surface where Sparse Autoencoders developed for alignment research can identify and surgically remove safety-related features

The CFA² (Causal Front-Door Adjustment Attack) demonstrates that Sparse Autoencoders — the same interpretability tool central to Anthropic's circuit tracing and feature identification research — can be used adversarially to mechanistically identify and remove safety-related features from model activations. The attack models LLM safety mechanisms as unobserved confounders and applies Pearl's Front-Door Criterion to sever these confounding associations. By isolating 'the core task intent' from defense mechanisms, the approach physically strips away protection-related components before generating responses, achieving state-of-the-art attack success rates. This is qualitatively different from traditional prompt-based jailbreaks: it uses mechanistic understanding of WHERE safety features live to selectively remove them. The surgical precision is more concerning than brute-force approaches because as interpretability research advances and more features get identified, this attack vector improves automatically. The same toolkit that enables understanding model internals for alignment purposes enables adversaries to strip away exactly those safety-related features. This establishes a structural dual-use problem where interpretability progress is simultaneously a defense enabler and attack amplifier.

Supporting Evidence

SCAV framework achieved 99.14% jailbreak success across seven open-source LLMs with black-box transfer to GPT-4, providing empirical confirmation that linear concept vector monitoring creates exploitable attack surfaces. The closed-form solution for optimal perturbation magnitude means attacks require no hyperparameter tuning, lowering the barrier to exploitation.
