What it detects

This rule detects use of the GAM command line tool to print or delete OAuth tokens across a Google Workspace tenant, activity observed both during attacker reconnaissance of consented apps and legitimate administrative cleanup. Because token enumeration reveals which third-party apps hold access, unexpected GAM token operations outside change windows can indicate an attacker mapping or pruning OAuth grants.
