How it works
This one is sneaky because the login is real. You click a link in an email offering a brand deal, an analytics dashboard, or an invite from a platform like GRIN, and you land on a genuine Google consent screen. The catch is the app requesting access. It asks for permission to manage your YouTube account or your Google data, and the app name is set to look like a legitimate tool. If you click Allow, Google issues the app a token, and from then on the attacker can act on your channel without your password and without tripping your 2FA, because you authorized it. Changing your password does not revoke it. The access lasts until you remove the app yourself.
Because the consent screen itself is hosted by Google, the usual "check the address bar" advice does not catch this. What catches it is reading the screen: which app is asking, what it wants, and whether you actually started this.
The tell-tale signals
- You did not go looking for this tool; the request arrived from a link in an email.
- The app name imitates a known platform, and the sender domain is a lookalike or free webmail rather than the platform's real domain. GRIN's real domain is grin.co, so a message from grin-creators.net is not GRIN.
- The permissions requested are broad, such as managing your YouTube account, for something that would not need that much.
- The link that brought you there used a shortener or an added-word domain.
- Pressure to approve quickly to claim the deal or unlock the dashboard.
What to do
Approve a Google consent screen only for an app you deliberately went to connect, and read exactly what it asks for before you click Allow. To see and remove apps that already have access, open your Google account permissions page at the third-party access section and revoke anything you do not recognize, then check YouTube Studio under Settings and Permissions for added users. If a marketplace deal is real, start from the platform you already use, not from an email link. Because this route bypasses passwords and 2FA, a passkey will not stop a grant you approve yourself, so the guard here is caution at the Allow button. LegitSponsor can assess the sender and link evidence on the original email before you reach the consent screen.
