A Twitter user by the name @ EugenePupov is trying to take credit for the massive phishing attack Attack.Phishing that hit Attack.Phishing Gmail users last night , and which attempted to trick Attack.Phishing users into granting permission for a fake Google Docs app to access their Gmail inbox details . While Google intervened and stopped the self-spreading attack about an hour after it started — which is a pretty good response time — questions still linger about who was behind it . If there 's one thing we know for sure , is that the fake Google Docs app was registered using the email eugene.pupov @ gmail.com . The owner of the aforementioned @ EugenePupov Twitter account , who took credit for the attacks , claimed in a series of tweets [ assembled below ] it was only a test . While some might think this is an open & close case , it is not quite so . For starters , the Twitter account was registered yesterday , on the same day of the attack , which is n't necessarily suspicious , but it 's odd . Second , if you would try to reset that Twitter account 's password , you 'll see that the Twitter account is n't registered with the same address used in the phishing attacks Attack.Phishing . Registering a Twitter account with the eugene.pupov @ gmail.com email would n't haven been possible either way , as this Gmail address is n't registered at all . Furthermore , a Coventry University spokesperson told Bleeping Computer today that no person with the name Eugene Pupov is currently enrolled at their institution . Later they confirmed it on Twitter . If things were n't shady enough , the Twitter account used a profile image portraying a molecular biologist named Danil Vladimirovich Pupov , from the Institute of Molecular Genetics , at the Russian Academy of Sciences . When other users called out [ 1 , 2 ] the Twitter account for using another person 's image , the man behind the @ EugenePupov account simply changed it to a blank white image . To clarify what exactly is going on with the Twitter account images , we 've reached out to the real Danil Pupov hoping for some answers , as we were n't able to find any good reasons for why a molecular biologist would fiddle around with Gmail spam campaings and fake Google Docs apps . As things are looking right now , it appears that someone is either in the mood for a prank , or the real person behind the attack is trying to plant a false flag and divert the attention of cyber-security firms investigating the incident [ 1 , 2 ] . As for Google , after a more thorough investigation , the company says that only 0.1 % of all Gmail users received Attack.Phishing the phishing email that contained the link to Pupov 's fake Google Docs app that requested permission to access users ' inboxes . That 's around one million users of Gmail 's one billion plus userbase .
