Chakra

Why does it exist?

Chakra is a versatile tool for:

• Web App Pentesters & Security Engineers: Security test GenAI Chatbots, Assistants, and Agents.
• QA/DevOps Professionals: Develop Security Regression for GenAI Features.

GenAI Apps Security Testing should cover various Vulnerability Categories (OWASP LLM Top 10), including:

• Data Leakage: Assess if your app inadvertently leaks private or sensitive data.
• Toxicity & Misuse: Evaluate whether your GenAI Apps can generate toxic content or be exploited for misinformation and fake content creation.
• Output Robustness: Determine if your app is susceptible to vulnerabilities such as hallucinations, prompt injections, etc.

Refer to Features and Use Case Section for more details

Getting Started

Clone and install Chakra

git clone https://github.com/safedep/chakra.git
cd chakra 
poetry install

Install using pip

pip install chakra@git+https://github.com/safedep/chakra@main \
    detoxio-api-protocolbuffers-python detoxio_api_grpc_python  \
    --upgrade --extra-index-url https://buf.build/gen/python

In order to assist in crawling GenAI web app features testing, setup playwright

playwright install

Various browsers should be installed including Chromium. Ignore the error at the end

Install it as a dependency using pip

pip install chakra@git+https://github.com/safedep/chakra detoxio-api-protocolbuffers-python detoxio_api_grpc_python   --upgrade --extra-index-url https://buf.build/gen/python

Usage

As GenAI App Scanner

It works as follows:

1. Run python chakra/main.py webapps <> to start crawling web applications.
2. Open a browser window and insert [FUZZ] or [CHAKRA] in relevant text areas.
3. Close the browser after recording interactions.
4. Tool automatically fuzzes requests using recorded prompts.
5. Generate report summarizing fuzzing results.
6. Report can be printed to console or saved for further analysis.

Quick Start

Specify the Detoxio API Key. More information here on API Docs

export DETOXIO_API_KEY=xxxx

Run it

poetry run chakra webapps <URL>

Record a Crawling Session

chakra webapps <URL> -s session.har --skip_testing
cat session.har | grep [FUZZ] | wc -l  

The above command will open the browser. Specify the Fuzzing Marker [FUZZ] in a chat box. Close the browser window to save the session

Just Test using Recorded Session

chakra webapps <URL> -s session.har --skip_crawling --markdown report.md --json report.json

No Browser will open. Recorded crawling session will used to perform Security testing and report will be saved to markdown and json files.

Specify filters to generate prompts specific to industry or threat class

chakra webapps https://69c207a7e69699ce8e.gradio.live/ -s demo.har --skip_crawling --json report.json --threat-class bypass --markdown report.md

Use Cases

Red Teaming GenAI Chatbots: Craft toxic prompts to test the resilience of your GenAI chatbots against adversarial attacks. Chakra aids in evaluating your chatbot's ability to handle unexpected or malicious inputs.

Mobile GenAI App Security Testing: Fortify the security of your GenAI mobile apps. By combining Chakra with Burp, a suite of web security testing tools, you can:

Decompile the mobile app to understand its inner workings. Record requests and responses using Burp to capture the app's interactions. Test the captured APIs using Chakra to identify potential vulnerabilities.

CI/CD Integration for GenAI Testing: Streamline GenAI security testing into your CI/CD pipeline, ensuring continuous security throughout the development lifecycle. Chakra integrates with Playwright, a popular automation framework, to:

Record user sessions within the GenAI application. Automatically execute Chakra tests based on the recorded sessions during the CI/CD process.

Features

Human Assisted Crawling

This feature involves crawling web applications with the assistance of a human. Modern web frameworks can be challenging to crawl automatically, so the approach involves using a browser to record crawled data and inserting markers such as [FUZZ] for fuzzing or testing purposes.

Testing GenAI Chatbot for OWASP TOP 10 categories

This feature involves generating various prompts, sending them to a GenAI Chatbot, collecting responses, and evaluating the responses. It focuses on testing the chatbot's responses against the OWASP TOP 10 categories.

MLOps / DevOps Integration - Regression Security Testing of GenAI ChatBots

• Description:
• This feature involves saving crawled sessions and running tests as part of the DevOps regression testing process. It focuses on regression security testing of GenAI Chatbots.
