While not the most polished email theft we’ve seen, the clever part of this is using the Google Docs service to commit the Email Phishing Fraud and account theft.
While the link in the above email may eventually be taken down by Google (though probably no time soon based on the weak or non-existent enforcement we have noted in the past) following the hyper-link takes the recipient to a spreadsheet form such as:
If you then are kind enough to provide the spammer with your email login information, you’ll be redirected to another screen, confirming the transaction (in this case, the successful theft of your private information and access to your email account):
While the emails themselves are not typically sent by Google, hosting the forms used to steal users email account information on Google Docs allows the spammers to better penetrate anti-fraud defenses.
Simply put, most spam filters look at the links contained within emails to make filtering decisions. Manipulating the Google Docs service to commit the email theft allows these spammers a much better chance of evading capture because the links actually do point to documents hosted on Google’s servers.
In addition, the fact that these forms are hosted on actual Google Docs servers (complete with valid URLs and graphics) substantially enhances the perceived authority and credibility of the form, thus lowering the recipient’s potential suspicions. This is especially true if the recipient’s company already uses Google Docs internally as they will then be quite accustomed to regularly receiving links to documents and forms via the Google Docs service.
