Open Source TypeScript Penetration Testing Tools

Shannon is an autonomous AI penetration testing system built to find and prove real, exploitable vulnerabilities in web applications rather than stopping at static warnings or best-guess alerts. It focuses on “proof by exploitation,” meaning it actively hunts for attack vectors in your code and then attempts to execute end-to-end exploits to demonstrate impact. The project blends source-aware analysis with automated web interaction so it can validate issues like injection flaws, authentication bypasses, and other exploitable paths in a way that resembles an actual attacker’s workflow. Instead of requiring you to manually reproduce findings, Shannon is designed to produce actionable evidence that a weakness can be weaponized, which helps teams prioritize what truly matters. It positions itself as a pre-attacker safety net, aiming to break your web app before someone else does and thereby reduce the gap between “potentially vulnerable” and “confirmed exploitable.”

If you are a developer, you can use Tamper Dev to debug your websites, or if you are a pentester, you can use it to search for security vulnerabilities by inspecting the HTTP traffic from your browser. Unlike most other extensions, Tamper Dev allows you to intercept, inspect and modify the requests before they are sent to the server. This extension provides functionality similar to Burp Proxy, MITM Proxy, OWASP ZAP, Tamper Data, and Postman Proxy, but without the need of additional software, with full support of HTTPS connections, and trivial to set-up (just install).

Inspecting a mobile app's HTTPS traffic using a proxy is probably the easiest way to figure out how it works. However, with the Network Security Configuration introduced in Android 7 and app developers trying to prevent MITM attacks using certificate pinning, getting an app to work with an HTTPS proxy has become quite tedious.

Santetin is a powerful desktop application built with Electron to perform website stress tests, penetration testing simulations, DDOS attacks, and traffic jingling for testing and educational purposes. ⚠️ Disclaimer: This tool is intended for educational and testing purposes only. Do not use it against any website without explicit permission from the owner.

Perform advanced MiTM attacks on websites with ease. Injectify is a modern web based MiTM tool, similiar to BeEF (although completely unrelated in terms of source code). It features cross-platform clients (Web, Desktop, Browser extension). Create a reverse Javascript shell between the victim and the attacker. Records keystrokes and logs them to a database.
