Problem
An attacker creates persistence through a connected application instead of changing the primary Google password.
Solution
Root Cause / Diagnostic:
Sophisticated threat actors maintain persistence by authorizing an external OAuth web application while inside a compromised session rather than altering the password, which would trigger instant owner alerts. This stealth persistence mechanism survives routine password changes and allows asynchronous channel commandeering.
Actionable Fix:
1. Comprehensive Security Disconnection: Access [link removed] and immediately revoke all newly added or unrecognized web apps, scripts, and extensions.
2. Google Workspace API Scopes Quarantine: If utilizing Google Workspace, block third-party API access globally across the organizational unit until each app is cryptographically verified.
3. Forensic Permission Audit: Verify that the list of connected apps contains zero third-party software authorized during the window of suspicious activity.
Pro Tip:
Clever hackers don't change your password right away; they connect their own malicious Google app to your account. When you reset your password, their backdoor app remains completely operational.
