Rogue app grabs contacts, peeks at inbox, spams everyone.
Final update If you get an email today sharing a Google Docs file with you, don’t click it – you may accidentally hand over your Gmail inbox and your contacts to a mystery attacker.
The phishing campaign really kicked off in a big way on Wednesday morning, US West Coast time. The malicious email contains what appears to be a link to a Google Doc file. This leads to a legit Google.com page asking you to authorize “Google Docs” to access to your Gmail account.
Except it’s not actually the official Google Docs requesting access: it’s a rogue web app with the same name that, if given the green light by unsuspecting marks, then ransacks contact lists and sends out more spam. It also gains control over the webmail account, including the ability to read victims’ messages and send new ones on their behalf.
Apparently no one at Google thought to block someone calling their app Google Docs.
If the permissions are granted, the software will immediately spam out the same message to all the people on your contacts list, bypassing two-factor authentication if you have that set up on your account. Here at Vulture West we’ve been getting bombarded with these emails, including some from journalists at other publications.
