In the ever-evolving landscape of cybersecurity, penetration testing has emerged as a crucial process for identifying vulnerabilities and strengthening the defense mechanisms of digital systems. Traditional penetration testing, however, can be time-consuming and heavily reliant on the expertise of the testers. Enter PentestGPT, a groundbreaking tool that harnesses the power of artificial intelligence to revolutionize the way penetration testing is conducted. Developed by a team of researchers led by Gelei Deng, PentestGPT leverages the capabilities of OpenAI's GPT-4 to automate and streamline the penetration testing process, making it more efficient, effective, and accessible to a wider range of users.
What is PentestGPT?
PentestGPT is an innovative penetration testing tool that combines the power of OpenAI's GPT-4 language model with a sophisticated architecture designed specifically for web penetration testing. By leveraging the advanced reasoning capabilities of GPT-4, PentestGPT can guide penetration testers through the complex process of identifying and exploiting vulnerabilities in web applications. The tool operates in an interactive mode, providing step-by-step guidance and generating precise commands for testers to execute, making the penetration testing process more intuitive and efficient.
Key Features
PentestGPT boasts an impressive array of features that set it apart from traditional penetration testing tools:
Automated Reasoning: PentestGPT's test reasoning module, powered by GPT-4, analyzes the target information and generates a task tree, guiding testers through the most effective testing sequence.
Command Generation: The test generation module creates precise penetration testing commands or operations for users to execute, eliminating the need for manual command creation.
Output Parsing: PentestGPT's parsing module intelligently analyzes the output of penetration tools and web UI contents, providing valuable insights and recommendations.
Interactive Guidance: The tool operates in an interactive mode, offering step-by-step guidance and facilitating discussions between the tester and PentestGPT for a more dynamic and collaborative testing experience.
Continuous Learning: As testers provide feedback and input, PentestGPT continuously learns and adapts, refining its strategies and enhancing its performance over time.

How to Use PentestGPT?
Using PentestGPT is an interactive and intuitive process. To start a penetration testing session, users simply provide the target information to the tool. PentestGPT then generates a task tree and guides the user through the testing process, providing precise commands to execute and analyzing the output of each step. Users can engage in discussions with PentestGPT, asking for clarification or additional information as needed. The tool also offers a continuous mode, allowing users to dive deeper into specific tasks and explore potential vulnerabilities in greater detail.
Follow these step-by-step instructions to use PentestGPT on your system:
Starting PentestGPT:
To start PentestGPT, run one of the following commands based on your access to the OpenAI API:
If you have access to the GPT-4 API (recommended):
Copy codepentestgpt --reasoning_model=gpt-4If you only have access to the GPT-3.5 API:
Copy codepentestgpt --reasoning_model=gpt-3.5-turbo-16k
Command-Line Arguments:
PentestGPT supports various command-line arguments to customize its behavior:
--help: Shows the help message.--reasoning_model: Specifies the reasoning model to use (e.g.,gpt-4,gpt-3.5-turbo-16k).--parsing_model: Specifies the parsing model to use.--useAPI: Determines whether to use the OpenAI API (default isTrue).--log_dir: Specifies the custom log output directory (relative path).--logging: Defines if you want to share logs with the developers (default isFalse).
Interacting with PentestGPT:
PentestGPT works similarly to the
msfconsoleinterface.Follow the guidance provided by PentestGPT to perform penetration testing.
PentestGPT accepts commands similar to ChatGPT. Some basic commands include:
help: Shows the help message.next: Allows you to input the test execution result and get the next step.more: Prompts PentestGPT to provide more details about the current step and creates a new sub-task solver for guidance.todo: Displays the todo list.discuss: Initiates a discussion with PentestGPT.google: Searches on Google (currently under development).quit: Exits the tool and saves the output as a log file.
