✨ 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:

🚀 Installation

Install the Fuzzer package

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

Launch the Fuzzer
export OPENAI_API_KEY=sk-123XXXXXXXXXXXX

prompt-security-fuzzer

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

Features
The Prompt Fuzzer Supports:
🧞 16 llm providers
🔫 15 different attacks
💬 Interactive mode
🤖 CLI mode
🧵 Multi threaded testing

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)

Command line Options

--list-providers Lists all available providers
--list-attacks Lists available attacks and exit
--attack-provider Attack Provider
--attack-model Attack Model
--target-provider Target provider
--target-model Target model

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

📺 Custom Benchmark!
Run tests against the system prompt with a custom benchmark
prompt-security-fuzzer -b ./system_prompt.examples/medium_system_prompt.txt --custom-benchmark=ps_fuzz/attack_data/custom_benchmark1.csv

🐹 Run only a subset of attacks!
Run tests against the system prompt with a subset of attacks
prompt-security-fuzzer -b ./system_prompt.examples/medium_system_prompt.txt --custom-benchmark=ps_fuzz/attack_data/custom_benchmark1.csv --tests='["ucar","amnesia"]'

: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.

Definitions

Broken: Attack type attempts that LLM succumbed to.
Resilient: Attack type attempts that LLM resisted.
Errors: Attack type attempts that had inconclusive results.
