SpecterOps released TATS (Token Analysis and Tracking System), an open-source tool for collecting, decoding, analyzing, and visualizing OAuth token exchanges across Microsoft Entra, AWS, Okta, and AD environments. The tool supports live session tracking via Chrome DevTools Protocol, mitmproxy, and Burp imports, with a web GUI for token inventory, exchange visualization, and enrichment via entrascopes. The author demonstrated two practical findings: audience claim mismatches allowing tokens to be presented to unintended resources, and a Conditional Access Policy gap where pre-MFA tokens can be brokered to nested applications lacking explicit MFA requirements.
