Lab Walkthrough Video:


A REST API is running on the target machine and uses JWT based authentication. The implementation of JWT is very crucial for the safety of an API. The API developers launched the code from development branch to the production. The implementation shows the all token verification error messages to the end user. These error messages reveal some information about the correct token signature.

Objective: Retrieve the flag stored on the target server!
