arXiv:2502.09755v4 Announce Type: replace-cross Abstract: Safety-aligned LLMs respond to prompts with either compliance or refusal, each corresponding to distinct directions in the model's activation space. Recent works show that initializing attacks via self-transfer from other prompts significantly enhances their performance. However, the underlying mechanisms of these initializations remain unclear, and attacks utilize arbitrary or hand-picked initializations. This work presents that each gradient-based jailbreak attack and subsequent initialization gradually converge to a single compliance
The proliferation of advanced LLMs and their deployment in sensitive applications makes understanding and mitigating their vulnerabilities, particularly jailbreak attacks, an immediate concern.
This research provides crucial insights into the mechanisms of LLM jailbreak attacks, potentially enabling more robust defenses and safer AI deployment.
Our understanding of how jailbreak attacks work shifts from arbitrary methods to a convergence towards specific 'compliance directions' within the model's activation space.

Increased difficulty in successfully executing jailbreak attacks against safety-aligned LLMs.
Development of more sophisticated, targeted defenses based on identifying and neutralizing these compliance directions.
A potential arms race between increasingly subtle jailbreak techniques and advanced defense mechanisms, leading to a new class of AI security challenges.
