A recent paper proposes using a hidden Markov model (HMM) to uniformly characterize attacker behavior-mode switching and the time-varying feasibility of action parameters, and achieves performance superior to recurrent baselines on the CAGE 2 benchmark.

VerifiedJailbreak techniques can be categorized into prompt injection, adversarial prefix attacks, multi-step context construction, and automated jailbreaking.68% similarUnverifiedThe hidden Markov preference model proposed in the paper treats the attacker's active behavior modes as hidden states, defines the action regularities under each mode on a 'feasibility mask tree' whose nodes correspond to executable actions, and the mask dynamically blocks infeasible action branches according to the current state.67% similarUnverifiedAfter the model is optimized to be more proactive, attacks that were previously avoided through laziness will reappear, manifesting as security regressions.65% similarUnverifiedThe PACT method attempts to directly model and adapt to interaction-induced non-stationarity, enabling agents to explicitly identify and adapt to distributional shifts caused by interactions with other agents.65% similarUnverifiedA recent study proposes that user embeddings can be understood as sparse superpositions of interpretable behavioral patterns.65% similar
