Making Them Ask and Answer: Jailbreaking Large Language Models in Few Queries via Disguise and Reconstruction
This addresses security threats for users and developers of LLMs by exposing vulnerabilities, though it is incremental as it builds on existing jailbreak techniques.
The paper tackles the problem of inducing harmful responses from large language models by identifying bias vulnerabilities in safety fine-tuning and introduces a black-box jailbreak method called DRA, which achieves a 91.1% attack success rate on OpenAI GPT-4 chatbot.
In recent years, large language models (LLMs) have demonstrated notable success across various tasks, but the trustworthiness of LLMs is still an open problem. One specific threat is the potential to generate toxic or harmful responses. Attackers can craft adversarial prompts that induce harmful responses from LLMs. In this work, we pioneer a theoretical foundation in LLMs security by identifying bias vulnerabilities within the safety fine-tuning and design a black-box jailbreak method named DRA (Disguise and Reconstruction Attack), which conceals harmful instructions through disguise and prompts the model to reconstruct the original harmful instruction within its completion. We evaluate DRA across various open-source and closed-source models, showcasing state-of-the-art jailbreak success rates and attack efficiency. Notably, DRA boasts a 91.1% attack success rate on OpenAI GPT-4 chatbot.
