Description: Users report receiving many spam/phishing messages that are not being detected. The message claims to be a Google Docs sharing notification. Once clicking the link, the user would be prompted to grant application permissions to both Gmail ("Read, send, delete, and manage your email") and Contacts ("Manage your contacts") scopes. The application sent the same phishing message to the user's contacts, but this effect has been mitigated.

We have taken action to protect our customers by:

* Disabling the offending Google accounts that generated the phishing link.

* Removing the fake Google login page that the link routes you to.

* Working to ensure that an incident like this doesn’t occur again in the future.

Workaround: We advise users to be careful when clicking links in email and granting access to applications unexpectedly. We encourage you to report phishing emails in Gmail (
