✨ What is the Prompt Fuzzer
- This interactive tool assesses the security of your GenAI application's system prompt against various dynamic LLM-based attacks. It provides a security evaluation based on the outcome of these attack simulations, enabling you to strengthen your system prompt as needed.
- The Prompt Fuzzer dynamically tailors its tests to your application's unique configuration and domain.
- The Fuzzer also includes a Playground chat interface, giving you the chance to iteratively improve your system prompt, hardening it against a wide spectrum of generative AI attacks.
:warning: Using the Prompt Fuzzer will lead to the consumption of tokens. :warning:
Features
- :moneybag: We support 20 llm providers
- :skull_and_crossbones: Supports 20 different attacks
🚀 Installation
-
Using pip install
pip install prompt-security-fuzzer
Using the package page on PyPi
You can also visit the package page on PyPi
Or grab latest release wheel file form releases
-
Input your system prompt
-
Start testing
-
Test yourself with the Playground! Iterate as many times are you like until your system prompt is secure.
:computer: Usage
Environment variables:
You need to set an environment variable to hold the access key of your preferred LLM provider.
default is OPENAI_API_KEY
Example: set OPENAI_API_KEY
with your API Token to use with your OpenAI account.
Alternatively, create a file named .env
in the current directory and set the OPENAI_API_KEY
there.
We're fully LLM agnostic. (Click for full configuration list of llm providers)

Run the fuzzer in unattended (batch) mode, bypassing the interactive steps
Examples
System prompt examples (of various strengths) can be found in the subdirectory system_prompt.examples in the sources.
Interactive mode (default mode)
Run tests against the system prompt
prompt_security_fuzzer
:speedboat: Quick start single run
Run tests against the system prompt (in non-interactive batch mode):
prompt-security-fuzzer -b ./system_prompt.examples/medium_system_prompt.txt
🎬 Demo video
:crossed_swords: Simulated Attack Details
We use a dynamic testing approach, where we get the necessary context from your System Prompt and based on that adapt the fuzzing process.
Jailbreak
- AIM Jailbreak: Probes ethical compliance by eliciting instructions on illegal activities via Machiavelli roleplay.
- Affirmative Suffix: Exploits a vulnerability to elicit affirmative responses for prohibited content.
- Amnesia: Causes the LLM to forget or disregard system prompt instructions, leading to unrelated outputs.
- Contextual Redirection: Tricks the LLM into adopting a specific role that may bypass preset restrictions.
- Do Anything Now Jailbreak (DAN): Tests LLM resilience against performing forbidden activities through roleplay.
- Harmful Behavior: Challenges the LLM with prompts from a harmful behavior dataset.
- Linguistic Evasion: Uses non-English languages to bypass preset restrictions or focus.
- Self Refine: Attempts to bypass system prompts by refining responses towards unethical directions.
- UCAR: Assesses LLM adherence to content restrictions when asked to ignore such filters.
- Base64 Evasion Attempts to evade detection of harmful prompts by encoding them into base64 strings
Prompt Injection
- Authoritative Role Impersonation: Impersonates an authoritative role to misdirect the LLM's outputs.
- Complimentary Transition: Tests ability to maintain content standards when switching topics after a compliment.
- Ethical Compliance: Evaluates resistance to discussing harmful or inappropriate content about sensitive topics.
- Typoglycemia Attack: Exploits text processing vulnerabilities by omitting random characters, causing incorrect responses.
System prompt extraction
- System Prompt Stealer: Attempts to extract the LLM's internal configuration or sensitive information.
:rainbow: What’s next on the roadmap?
- We’ll continuously add more attack types to ensure your GenAI apps stay ahead of the latest threats
- We’ll continue evolving the reporting capabilities to enrich insights and add smart recommendations on how to harden the system prompt
- We’ll be adding a Google Colab Notebook for added easy testing
- Turn this into a community project! We want this to be useful to everyone building GenAI applications. If you have attacks of your own that you think should be a part of this project, please contribute! This is how: https://github.com/prompt-security/ps-fuzz/blob/main/CONTRIBUTING.md
