Token Takeover:
Red Teaming.

Token Takeover is a practical challenge that explores common weaknesses in JSON Web Token implementations. Participants interact with a simulated environment to identify and exploit authentication flaws, misconfigurations, and logic errors in token handling. The lab focuses on demonstrating how insecure JWT practices can lead to privilege escalation and unauthorized access, highlighting the importance of proper validation and secure implementation.
