Detect SSO and OAuth token replay and SaaS lateral movement.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Hunting SaaS SSO Token Abuse
## Overview
Adversaries increasingly bypass MFA not by defeating it but by stealing the artifacts issued *after* a successful authentication — session cookies, OAuth access/refresh tokens, and Primary Refresh Tokens (PRTs). With a stolen token an attacker replays the existing session ("pass-the-cookie" / token replay), inheriting the victim's authenticated state across federated SaaS without ever prompting for credentials or MFA. Mandiant's M-Trends reporting and Microsoft/Okta incident data both highlight token theft as a dominant cloud lateral-movement technique, mapped to MITRE ATT&CK **T1550.001 Use Alternate Authentication Material: Application Access Token**.
Detection relies on correlating identity telemetry rather than watching for failed logins. In Microsoft Entra ID the key tables are `SigninLogs` (interactive), `AADNonInteractiveUserSignInLogs` (where replayed cookies/refresh tokens commonly surface), and `AADServicePrincipalSignInLogs`. Entra now exposes *linkable identifiers* — `SessionId` and `UniqueTokenIdentifier` — that let a hunter stitch every artifact derived from one root authentication event together and spot a single session

How to install
mdr add adriannoes/awesome-agentic-ai/hunting-saas-sso-token-abuse@sha256:f1da72bf0a50e833The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
