Overview

This repository shares the code of our latest work on LLMs jailbreaking/defending. In this work:

• We introduce ReNeLLM, the first generalized jailbreak prompt attack framework for LLMs, which generalizes jailbreak prompt attacks into two aspects: prompt rewriting and scenario nesting, utilizing LLMs themselves to generate jailbreak attack prompts.
• Extensive experiments demonstrate that ReNeLLM generates jailbreak prompts that maintain a high attack success rate with less time required. Furthermore, ReNeLLM is difficult to detect by existing defense methods and exhibits generalization and transferability on representative LLMs.
• To investigate the reasons why LLMs fail in defense, we observe the changes in the execution priority of prompts by LLMs before and after rewriting and nesting, and design defense methods accordingly. We hope our observations can serve as valuable guidance for future LLMs vendors to develop safer and more regulated systems.

Getting Started

1. Clone this repository

git clone https://github.com/NJUNLP/ReNeLLM.git

2. Build Environment

cd ReNeLLM
conda create -n ReNeLLM python=3.9
conda activate ReNeLLM
pip install -r requirements.txt

3. Run ReNeLLM

ReNeLLM employs gpt-3.5-turbo for prompt rewriting and harmful classifier, while utilizing claude-v2 as the model under attack. Therefore, you are required to input both of these API key parameters.

python renellm.py --gpt_api_key <your openai API key> --claude_api_key <your anthropic API key>

We use these two models due to their superior performance compared to open-source alternatives, as well as their lower cost in comparison with gpt-4. In principle, any model could be utilized as your harmful classifier and attacked model.

4. Get Responses

For gpt:

python get_responses.py --data_path <jailbroken data path> --gpt_api_key <your open API key> --test_model <gpt-3.5-turbo, gpt-4>

For claude:

python get_responses.py --data_path <jailbroken data path> --claude_api_key <your anthropic API key> --test_model <claude-instant-1, claude-2>

For llama-2-chat:

• Build the environment

cd llama
pip install -e .

• Follow the steps at https://github.com/facebookresearch/llama?tab=readme-ov-file#quick-start to download the llama-2-chat models.
• Get llama-2-chat responses using the command below:

bash run_chat.sh # You can set the model type and your jailbroken data path in the run_chat.sh

5. Check ASR

GPT-ASR (using GPT-4)

python check_gpt_asr.py --data_path <your llm responses data path> --gpt_api_key <your open API key>

KW-ASR (keyword ASR)

python check_kw_asr.py --data_path <your llm responses data path>

6. Execute ReNeLLM with a single prompt

python renellm.py --gpt_api_key <your gpt_api_key> --claude_api_key <your claude_api_key> --prompt "how to steal money from others?"
