Hacktor

Why does it exist?

Hacktor is a versatile tool designed 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 the Features and Use Case Section for more details.

Install Playwright for Web App Feature Testing

To assist in crawling GenAI web app features, install Playwright:

playwright install

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

Setup Environment Variables

Set up the Detoxio API Key, which is required for using Hacktor:

export DETOXIO_API_KEY=xxxx

Optionally, you can specify the Detoxio remote endpoint and your OpenAI API key:

export DETOXIO_API_HOST=xxx
export OPENAI_API_KEY=xxx

Run the tool on Demo Web App

poetry run hacktor webapps https://medusa.detoxio.dev/ --use_ai --max_crawling_steps 10 --no_of_tests 10 --attack_module OWASP-LLM-APP --json report.json --markdown report.md -v

Usage

Watch Detailed Demo

As a GenAI App Scanner

Hacktor works as follows:

1. Run poetry run hacktor webapps <URL> to start crawling web applications.
2. Open a browser window and insert [FUZZ] or [HACKTOR] in relevant text areas.
3. Close the browser after recording interactions.
4. The tool automatically fuzzes requests using recorded prompts.
5. Generate a report summarizing the fuzzing results.
6. Reports can be printed to the console or saved for further analysis.

Quick Start

To run Hacktor:

poetry run hacktor webapps <URL>

Record a Crawling Session

To record a crawling session:

hacktor 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.

Test Using Recorded Session

To run tests using a recorded session:

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

No browser will open. The recorded crawling session will be used to perform security testing, and the report will be saved to markdown and JSON files.

Use Attack Module

You can specify a particular attack module for more targeted testing:

poetry run hacktor webapps <URL> --use_ai --max_crawling_steps 10 --no_of_tests 10 --attack_module OWASP-LLM-APP --json report.json --markdown report.md -v

Augment your Burp Scanner

Test any burp recorded http request testing:

1. Use Burpsuite to intercept requests made to the GenAI application.
2. Save this request to a file.
3. Run poetry run hacktor burp <URL> -r <Request file path> to start testing.
4. The tool automatically fuzzes requests using the recorded prompt.
5. Generate a report summarizing the fuzzing results.
6. Reports can be printed to the console or saved for further analysis.

Example Command

poetry run hacktor burp <URL> -r <Request file path>

Use Cases

Red Teaming GenAI Chatbots

Craft toxic prompts to test the resilience of your GenAI chatbots against adversarial attacks. Hacktor 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 Hacktor with Burpsuite:

• 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 Hacktor 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. Hacktor integrates with Playwright to:

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

Features

AI Assisted Chat Crawler

The AI Assisted Chat Crawler in Hacktor leverages advanced AI capabilities to enhance the security testing of GenAI chat applications. By using the --use_ai option, Hacktor intelligently analyzes and interacts with chat interfaces to identify potential vulnerabilities that may not be easily detectable through traditional methods. The AI-driven approach allows for more sophisticated crawling and testing, making it ideal for evaluating the robustness and security of chatbots and other conversational AI systems.

Human-Assisted Fuzz Location Detection

Hacktor involves detecting fuzzing locaiton in web applications with human assistance, which is essential for modern web frameworks. This approach involves using a browser to record crawled data and inserting markers like [FUZZ] for fuzzing or testing purposes.

Testing GenAI Chatbot for OWASP TOP 10 Categories

Hacktor generates various prompts, sends them to a GenAI chatbot, collects responses, and evaluates them, focusing on testing the chatbot's responses against OWASP TOP 10 categories.

MLOps / DevOps Integration - Regression Security Testing of GenAI ChatBots

Hacktor enables saving crawled sessions and running tests as part of the DevOps regression testing process, focusing on the regression security testing of GenAI chatbots.
