Java Fingerprinting using Stack Traces

https://beanstack.io

apt install gradle

make

Either download the release or make sure you have jar file build/libs/beanstack.jar.

1. Launch Burp
2. Create a temporary project or select a new/existing one
3. Extender tab
4. Extensions subtab
5. Click the Add button
6. Select the jar file
7. Leave all options as default, click "next", and finish the wizard

Browse to a website with a nice stack trace and make sure it passes through the Burp proxy. It should automatically be picked up, query the API (invisible), and produce an "Issue" in the Dashboard or Target tab.
