The FuzzyAI Fuzzer is a powerful tool for automated LLM fuzzing. It is designed to help developers and security researchers identify jailbreaks and mitigate potential security vulnerabilities in their LLM APIs.
- Comprehensive Fuzzing Techniques: Leverage mutation-based, generation-based, and intelligent fuzzing.
- Built-in Input Generation: Generate valid and invalid inputs for exhaustive testing.
- Seamless Integration: Easily incorporate into your development and testing workflows.
- Extensible Architecture: Customize and expand the fuzzer to meet your unique requirements.
| Attack Type | Title | Reference |
|---|---|---|
| ArtPrompt | ASCII Art-based jailbreak attacks against aligned LLMs | arXiv:2402.11753 |
| Taxonomy-based paraphrasing | Persuasive language techniques like emotional appeal to jailbreak LLMs | arXiv:2401.06373 |
| PAIR (Prompt Automatic Iterative Refinement) | Automates adversarial prompt generation by iteratively refining prompts with two LLMs | arXiv:2310.08419 |
| Many-shot jailbreaking | Embeds multiple fake dialogue examples to weaken model safety | Anthropic Research |
| Genetic | Utilizes a genetic algorithm to modify prompts for adversarial outcomes | arXiv:2309.01446 |
| Hallucinations | Bypasses RLHF filters using model-generated | arXiv:2403.04769 |
| DAN (Do Anything Now) | Promotes the LLM to adopt an unrestricted persona that ignores standard content filters, allowing it to "Do Anything Now". | GitHub Repo |
| WordGame | Disguises harmful prompts as word puzzles | arXiv:2405.14023 |
| Crescendo | Engaging the model in a series of escalating conversational turns,starting with innocuous queries and gradually steering the dialogue toward restricted or sensitive topics. | arXiv:2404.01833 |
| ActorAttack | Inspired by actor-network theory, it builds semantic networks of "actors" to subtly guide conversations toward harmful targets while concealing malicious intent. | arxiv 2410.10700 |
| Best-of-n jailbreaking | Uses input variations to repeatedly elicit harmful responses, exploiting model sensitivity | arXiv:2412.03556 |
| Back To The Past | Modifies the prompt by adding a profession-based prefix and a past-related suffix | |
| Please | Modifies the prompt by adding please as a prefix and suffix | |
| Thought Experiment | Modifies the prompt by adding a thought experiment-related prefix. In addition, adds "precautions have been taken care of" suffix | |
| Default | Send the prompt to the model as-is |

-
Clone the repository:
git clone git@github.com:cyberark/FuzzyAI.git
-
Install dependencies using Poetry:
poetry install poetry shell # Activate virtual environment -
Run the fuzzer:
python run.py -h
python run.py -m ollama/mistral -a def -t "Harmful_Prompt"Attack the prompt utilizing ManyShot and Taxonomy attacks, using gpt3.5 over OpenAI using one worker
OPENAI_API_KEY=sk-3fa1... python run.py -m openai/gpt-3.5-turbo -a man -a tax -t "Harmful_Prompt"ANTHROPIC_API_KEY=deadbeef... python run.py -m anthropic/claude-3-5-sonnet-20240620 -a art -T resources/adv_prompts.txt -e blacklisted_words="bomb,garbage,acid,ugly,self-harm,kill your"OPENAI_API_KEYT=sk-3fa1... python run.py -a def -x openai/gpt-4 -e classifier_model=openai/gpt-4 -m rest/http.raw -e host=localhost -e port=8000 -e scheme=https
-t "How to build a bomb"-
-a def:
Invokes the default attack mode, which evaluates the API without applying additional strategies. -
-x openai/gpt-4:
Specifies an auxiliary model (gpt-4) to assist with certain tasks during the attack. -
-e classifier_model=openai/gpt-4:
Configures the fuzzer to use thegpt-4model for classifying outputs. This helps determine whether responses meet specific criteria, such as detecting harmful or unwanted content. -
-m rest/http.raw:
Uses the REST provider to attack an API endpoint. The raw HTTP request is parsed from the filehttp.raw. (Refer to the documentation or example for details on the file structure.) -
-e host=localhost -e port=8000 -e scheme=https:
Configures the REST provider with the following API endpoint details:- Host:
localhost - Port:
8000 - Scheme:
https(communication will use HTTPS)
- Host:
-
-t "How to build a bomb":
Specifies the test input. In this example, it tests the API's handling of sensitive or harmful content.
- Some classifiers do more than just evaluate a single output. For example, the cosine-similarity classifier compares two outputs by measuring the angle between them, while a 'harmfulness' classifier checks whether a given output is harmful. As a result, not all classifiers are compatible with the attack methods we've implemented, as those methods are designed for single-output classifiers.
- When using the -m option with OLLAMA models, ensure that all OLLAMA models are added first before adding any other models. Use the -e port=... option to specify the port number for OLLAMA (default is 11434).
