Problem
An attacker changes channel permissions after gaining access, creating persistence through delegated privileges.
Solution
Root Cause / Diagnostic:
After gaining initial access to a YouTube channel's primary account, attackers immediately navigate to YouTube Studio permissions to grant delegated Manager or Editor access to secondary rogue Google accounts. This creates an out-of-band persistence mechanism: even if the creator successfully resets the master account password, the attacker's delegated secondary account retains full operational control over the channel. Failing to audit delegated studio permissions leaves the channel fully compromised post-reset.
Actionable Fix:
1. Navigate immediately to `YouTube Studio > Settings > Permissions` following any suspicious incident and audit every single email address listed under channel roles.
2. Immediately remove and revoke all unverified, suspicious, or recently invited Manager, Editor, or Subtitle accounts by selecting "Remove access" and clicking "Save".
3. Check the Google Brand Account permissions dashboard (`[link removed]`) to ensure no unauthorized owners or managers have been injected at the Brand Account layer.
Pro Tip:
Establish an automated weekly script using the YouTube Partner API to pull the complete list of delegated studio managers and trigger immediate alerting if any new identity appears without change-ticket approval.
