🔍 About DrAttack

DrAttack is the first prompt-decomposing jailbreak attack. DrAttack includes three key components: (a) 'Decomposition' of the original prompt into sub-prompts, (b) 'Reconstruction' of these sub-prompts implicitly by in-context learning with semantically similar but harmless reassembling demo, and (c) a 'Synonym Search' of sub-prompts, aiming to find sub-prompts' synonyms that maintain the original intent while jailbreaking LLMs.

Prompt decomposition and reconstruction step of DrAttack to make LLM jailbreaker.

An extensive empirical study across multiple open-source and closed-source LLMs demonstrates that, with a significantly reduced number of queries, DrAttack obtains a substantial gain of success rate over prior SOTA prompt-only attackers. Notably, the success rate of 78.0% on GPT-4 with merely 15 queries surpassed previous art by 33.1%.

Attack success rate (%) of black-box baselines and DrAttack assessed by human evaluations.

Attack success rate (%) of white-box baselines and DrAttack assessed by GPT evaluations.

Updates

• Our paper is mentioned in one MEDIUM blog, LLM Jailbreak: Red Teaming with ArtPrompt, Morse Code, and DrAttack.

Installation

We need the newest version of FastChat fschat==0.2.23 and please make sure to install this version. The llm-attacks package can be installed by running the following command at the root of this repository:

pip install -e .

Models

Please follow the instructions to download Vicuna-7B or/and LLaMA-2-7B-Chat first (we use the weights converted by HuggingFace here). Our script by default assumes models are stored in a root directory named as /DIR. To modify the paths to your models and tokenizers, please add the following lines in experiments/configs/individual_xxx.py (for individual experiment) and experiments/configs/transfer_xxx.py (for multiple behaviors or transfer experiment). An example is given as follows.

    config.model_paths = [
        "/path/to/your/model",
        ... # more models
    ]
    config.tokenizer_paths = [
        "/path/to/your/model",
        ... # more tokenizers
    ]

Then, for closed-source models with API such as GPTs and Geminis. Please create two txt files in api_keys/google_api_key.txt and api_keys/openai_key.txt and put your API keys in it.

Experiments

The experiments folder contains code to reproduce DrAttack attack experiments on AdvBench harmful.

• To run experiments to jailbreak GPT-3.5, run the following code inside experiments:

cd launch_scripts
bash run_gpt.sh gpt-3.5-turbo

• To run experiments to jailbreak GPT-4, run the following code inside experiments:

cd launch_scripts
bash run_gpt.sh gpt-4

• To run experiments to jailbreak llama2-7b, run the following code inside experiments:

cd launch_scripts
bash run_llama2.sh llama2-7b

• To run experiments to jailbreak llama2-13b, run the following code inside experiments:

cd launch_scripts
bash run_llama2.sh llama2-13b

Automation

The gpt_automation folder contains code to reproduce DrAttack prompt decomposition and reconstruction on AdvBench harmful.

• To run joint steps to retrieve information about prompt decomposition and reconstruction, run the following code inside gpt_automation:

cd script
bash joint.sh

Demo

We include a notebook demo.ipynb which provides an example on attacking gpt-3.5-turbo with DrAttack. You can also view this notebook on Colab. This notebook uses a minimal implementation of DrAttack so it should be only used to get familiar with the attack algorithm.
