Depth Charge: Jailbreak Large Language Models from Deep Safety Attention Heads

arXiv – CS AI|Jinman Wu, Yi Xie, Shiqian Zhao, Xiaofeng Chen|
πŸ€–AI Summary

Researchers have developed SAHA (Safety Attention Head Attack), a new jailbreak framework that exploits vulnerabilities in deeper attention layers of open-source large language models. The method improves attack success rates by 14% over existing techniques by targeting insufficiently aligned attention heads rather than surface-level prompts.

Key Takeaways
  • β†’SAHA targets deeper attention layers in LLMs, revealing vulnerabilities that shallow-level defenses miss.
  • β†’The framework uses Ablation-Impact Ranking to identify the most vulnerable layers for unsafe output generation.
  • β†’Layer-Wise Perturbation enables minimal changes to attention mechanisms while maintaining semantic relevance.
  • β†’SAHA achieves 14% higher attack success rate compared to state-of-the-art baseline methods.
  • β†’Open-source LLMs remain vulnerable to sophisticated attacks even after safety alignment procedures.
