Session
Standard OIDC bearer tokens are deceptively simple and highly attractive to developers, but they hide a structurally weak security posture: anyone who holds them can spend them. Following up on our previous deep dive @MOCA24 into securing OIDC code exchanges, this presentation is a hands-on, exploit-driven exploration of token-usage security.
We will begin by demonstrating how easily standard bearer tokens are stolen and replayed remotely from an attacker's terminal. We will then look "beyond the basics" to live-demo a hardened implementation of RFC 9449 (DPoP) using a Keycloak identity provider and an Express.js resource server.
