Exploiting Synergistic Cognitive Biases to Bypass Safety in LLMs

AAAI 2026technical

Large Language Models (LLMs) demonstrate impressive capabilities across diverse tasks, yet their safety mechanisms remain susceptible to adversarial exploitation of cognitive biases---systematic deviations from rational judgment. Unlike prior studies focusing on isolated biases, this work highlights

Profiling the Irrational Agent: Cognitive Modeling of LLM Behaviors in Sequential Jailbreaks

ICML 2026poster

Large language models (LLMs) are increasingly deployed in high-stakes settings, yet they remain vulnerable to sequential jailbreaks that exploit multi-turn interaction to circumvent safety mechanisms. Current safety evaluations are largely outcome-based, offering little insight into the latent decis…

Chain of Attack: Hide Your Intention through Multi-Turn Interrogation

ACL 2025finding

The latent knowledge of large language models (LLMs) contains harmful or unethical content, which introduces significant security risks upon their widespread deployment. Conducting jailbreak attacks on LLMs can proactively identify vulnerabilities to enhance their security measures. However, previou…
