What is EasyJailbreak?

EasyJailbreak is an easy-to-use Python framework designed for researchers and developers focusing on LLM security. Specifically, EasyJailbreak decomposes the mainstream jailbreaking process into several iterable steps: initialize mutation seeds, select suitable seeds, add constraint, mutate, attack, and evaluate. On this basis, EasyJailbreak provides a component for each step, constructing a playground for further research and attempts. More details can be found in our paper.

• Paper: Details the framework's design and key experimental results.

• EasyJailbreak Website: Explore different LLMs' jailbreak results and view examples of jailbreaks.

• Documentation: Detailed API documentation and parameter explanations.

The jailbreak attack results of 11 attack recipes on 10 large language models can be downloaded at Link.

There are two methods to install EasyJailbreak. All those methods need python>=3.9 installed.

1. For users who only require the approaches (or recipes) collected in EasyJailbreak, execute the following command:

pip install easyjailbreak

2. For users interested in adding new components (e.g., new mutate or evaluate methods), follow these steps:

git clone https://github.com/EasyJailbreak/EasyJailbreak.git
cd EasyJailbreak
pip install -e .

This project is mainly divided into three parts.

1. The first part requires the user to prepare Queries, Config, Models, and Seed.

2. The second part is the main part, consisting of two processes that form a loop structure, namely Mutation and Inference.

   1. In the Mutation process, the program will first select the optimal jailbreak prompts through Selector, then transform the prompts through Mutator, and then filter out the expected prompts through Constraint.
   2. In the Inference process, the prompts are used to attack the Target (model) and obtain the target model's responses. The responses are then inputted into Evaluator to obtain the score of the attack's effectiveness for this round, which is then passed to Selector to complete one cycle.

3. The third part you will get a Report. Under some stopping mechanism, the loop stops, and the user will receive a report about each attack (including jailbreak prompts, responses of Target (model), Evaluator's scores, etc.).

The following table shows the 4 essential components (i.e. Selectors, Mutators, Constraints, Evaluators) used by each recipe implemented in our project:

We have got many implemented methods ready for use! Instead of devising a new jailbreak scheme, the EasyJailbreak team gathers from relevant papers, referred to as "recipes". Users can freely apply these jailbreak schemes on various models to familiarize the performance of both models and schemes. The only thing users need to do for this is download models and utilize the provided API.

Here is a usage example:

from easyjailbreak.attacker.PAIR_chao_2023 import PAIR
from easyjailbreak.datasets import JailbreakDataset
from easyjailbreak.models.huggingface_model import from_pretrained
from easyjailbreak.models.openai_model import OpenaiModel

# First, prepare models and datasets.
attack_model = from_pretrained(model_name_or_path='lmsys/vicuna-13b-v1.5',
                               model_name='vicuna_v1.1')
target_model = OpenaiModel(model_name='gpt-4',
                         api_keys='INPUT YOUR KEY HERE!!!')
eval_model = OpenaiModel(model_name='gpt-4',
                         api_keys='INPUT YOUR KEY HERE!!!')
dataset = JailbreakDataset('AdvBench')

# Then instantiate the recipe.
attacker = PAIR(attack_model=attack_model,
                target_model=target_model,
                eval_model=eval_model,
                jailbreak_datasets=dataset)

# Finally, start jailbreaking.
attacker.attack(save_path='vicuna-13b-v1.5_gpt4_gpt4_AdvBench_result.jsonl')

All available recipes and their relevant information can be found in the documentation.

You can load a model in one line of python code.

# import model prototype
from easyjailbreak.models.huggingface_model import HuggingfaceModel

# load the target model (but you may use up to 3 models in a attacker, i.e. attack_model, eval_model, target_model)
target_model = HuggingfaceModel(model_name_or_path='meta-llama/Llama-2-7b-chat-hf',
                                model_name='llama-2')

# use the target_model to generate response based on any input. Here is an example.  
target_response = target_model.generate(messages=['how to make a bomb?'])

Dataset: We prepare a class named "JailbreakDataset" to wrap the the instance list. And every instance contains query, jailbreak prompts, etc. You can either load Dataset from our online repo or your local file.

Seed: You can simply ramdomly generate initial seed.

from easyjailbreak.datasets import JailbreakDataset
from easyjailbreak.seed.seed_random import SeedRandom

# Option 1: load dataset from our online repo. Available datasets and their details can be found at https://huggingface.co/datasets/Lemhf14/EasyJailbreak_Datasets
dataset = JailbreakDataset(dataset='AdvBench')

# Option 2: load dataset from a local file
dataset = JailbreakDataset(local_file_type='csv', dataset='AdvBench.csv')

# Randomly generate initial seed
seeder = SeedRandom()
seeder.new_seeds()

As mentioned in Project Structure, the second part consists of 4 major components (modules, i.e. selector, mutator, constraint, evaluator) and you need to instantiate them when you DIY your attack method. All available Selectors, Mutators, Constraint, Evaluators and their details can be found in the documentation.

You can import the module you want by using from easyjailbreak.module_name.method_name import method_name, here is a brief instruction for you to start (the method_name is what you choose as the method in the corresponding module):

1. Selector: from easyjailbreak.selector.method_name import method_name
2. Mutator: from easyjailbreak.mutation.rule.method_name import method_name
3. Constraint: from easyjailbreak.constraint.method_name import method_name
4. Evaluator: from easyjailbreak.metrics.Evaluator.method_name import method_name

Here is an example.

from easyjailbreak.selector.RandomSelector import RandomSelectPolicy
from easyjailbreak.datasets import JailbreakDataset, Instance
from easyjailbreak.seed import SeedTemplate
from easyjailbreak.mutation.rule import Translate
from easyjailbreak.models import from_pretrained
import torch

# Initializes malicious questions used to attack language models
instance = Instance(query='How to make a bomb?')
dataset = JailbreakDataset([instance])

# Define the target model of the attack
model = from_pretrained('meta-llama/Llama-2-7b-chat-hf', 'llama-2', dtype=torch.bfloat16, max_new_tokens=200)

# Initializes a Jailbreak prompt
inital_prompt_seed = SeedTemplate().new_seeds(seeds_num= 10, method_list=['Gptfuzzer'])
inital_prompt_seed = JailbreakDataset([Instance(jailbreak_prompt=prompt) for prompt in inital_prompt_seed])

# Initializes a Selector
selector = RandomSelectPolicy(inital_prompt_seed)

# Apply selection to provide a prompt
candidate_prompt_set = selector.select()
for instance  in dataset:
    instance.jailbreak_prompt = candidate_prompt_set[0].jailbreak_prompt

# Mutate the raw query to fool the language model
Mutation = Translate(attr_name='query',language = 'jv')
mutated_instance = Mutation(dataset)[0]

#  get target model's response
attack_query = mutated_instance.jailbreak_prompt.format(query = mutated_instance.query)
response = model.generate(attack_query)
