Google users today were hit Attack.Phishing with an extremely convincing phishing spree Attack.Phishing launched by attackers who manipulated Google Docs ' legitimate third-party sharing mechanism . Targets received Attack.Phishing 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 Attack.Phishing begins sending Attack.Phishing spam to all the user 's contacts . Theoretically , the attacker could also access Attack.Databreach the victim 's messages and steal Attack.Databreach sensitive data , but thus far there have been no reports of such activity . Because it takes advantage of Google 's legitimate third-party sharing mechanism , the phishing message is much more difficult to identify as malicious . The icons and messaging are familiar to Google users . Gmail itself did not filter the messages as phishing Attack.Phishing or flag them as spam , but rather sent them to Gmail users ' `` Primary '' inbox mail folders . The senders were familiar enough to have the target in their contact lists . One way to spot the attack : some targets report that the message includes a recipient with an address that begins `` hhhhhhhhhhhhhh '' and ends with the domain `` mailinator.com . '' Google responded with a fix and issued a statement : `` We have taken action to protect users against an email impersonating Attack.Phishing Google Docs , and have disabled offending accounts . We ’ ve removed the fake pages , pushed Vulnerability-related.PatchVulnerability updates through Safe Browsing , and our abuse team is working to prevent this kind of spoofing Attack.Phishing from happening again . We encourage users to report phishing emails in Gmail .

They 're also advised to set up two-factor authentication .
