Google users were hit with an extremely convincing phishing spree. Targets received messages with the subject like "[Sender] has shared a document on Google Docs with you" often from senders they knew. The messages contained links, which led to a page that clearly requested access to the user's Gmail account. If the target user provides access, the attack begins sending spam to all the user's contacts. Google responded with a fix and issued a statement. Those who have already fallen victim to this attack should also go to their Google account permissions settings and revoke access to the false "Google Docs" application. They're also advised to set up two-factor authentication and visit http://g.co/SecurityCheckup.
