A massive phishing campaign targeting Google accounts ripped through the internet on Wednesday afternoon.

Several people online across a range of industries said they received emails containing what looked like a link to a Google Doc that appeared to come from someone they know. These, however, were malicious emails designed to hijack their accounts. 

If you have clicked on the link, go to your Google account's page (https://myaccount.google.com/permissions) where you can manage the permissions you've granted to apps (or go through the whole Google Security Checkup). Then locate the "Google Doc" app. This looks totally legitimate, but it's actually not. If that's the malicious app that's gotten access to your account after you clicked on the link it should have a recent "Authorization Time." Now, click on that Google Docs app and click "Remove".
