Google Docs was pulled into a sneaky email phishing attack Attack.Phishing on Tuesday that was designed to trick Attack.Phishing users into giving up access to their Gmail accounts . The phishing emails , which circulated Attack.Phishing for about three hours before Google stopped them , invited Attack.Phishing the recipient to open what appeared to be Attack.Phishing a Google Doc . The teaser was a blue box that said , “ Open in Docs. ” In reality , the link led to a dummy app that asked users for permission to access their Gmail account . An example of the phishing email that circulated Attack.Phishing on Tuesday . Users might easily have been fooled Attack.Phishing , because the dummy app was actually named “ Google Docs. ” It also asked for access to Gmail through Google ’ s actual login service . The hackers were able to pull off the attack by abusing the OAuth protocol , a way for internet accounts at Google , Twitter , Facebook and other services to connect with third-party apps . The OAuth protocol doesn ’ t transfer any password information , but instead uses special access tokens that can open account access . However , OAuth can be dangerous in the wrong hands . The hackers behind Tuesday’s attack Attack.Phishing appear to have built Attack.Phishing an actual third-party app that leveraged Google processes to gain account access . The dummy app will try to ask for account permission . Last month , Trend Micro said a Russian hacking group known as Fancy Bear was using a similar email attack method that abused the OAuth protocol to phish Attack.Phishing victims . However , security experts said Tuesday's phishing attack Attack.Phishing probably was n't from Fancy Bear , a shadowy group that many experts suspect works for the Russian government . `` I do n't believe they are behind this ... because this is way too widespread , '' Jaime Blasco , chief scientist at security provider AlienVault , said in an email . On Tuesday , many users on Twitter , including journalists , posted screen shots of the phishing emails , prompting speculation that the hackers were harvesting Attack.Databreach victims ' contact lists to target more users . The attack Attack.Phishing was also sent Attack.Phishing through an email address at `` hhhhhhhhhhhhhhhh @ mailinator.com . '' Mailinator , a provider of a free email service , denied any involvement . Fortunately , Google moved quickly to stop the phishing attacks Attack.Phishing , after a user on Reddit posted about them . “ 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 , ” Google said in a statement . Security experts and Google recommend affected users check what third-party apps have permission to access their account and revoke any suspicious access . Users can do so by visiting this address , or performing a Google security check-up . Tuesday's phishing scheme Attack.Phishing will probably push Google to adopt an even stricter stance on apps that use OAuth , said Robert Graham , CEO of research company Errata Security . However , the internet giant has to strike a balance between ensuring security and fostering a flourishing app ecosystem . `` The more vetting you do , the more you stop innovation , '' Graham said . `` It 's a trade-off .
