"A friend" received and e-mail with badly translated text in it. The translation into Finnish was so bad that I couldn't even read it myself. But as always, there was something to lure innocent user to click. A shortened link.
In this case, the link wasn't especially dangerous. It didn't exploit any security flaws or didn't do anything dangerous. It simply landed on some innocent victim's WordPress 3.9.3 site with some "bonus" material injected into it. At the time of writing, latest WP version is 4.1.
The users were presented a "Google Drive login" page:
Would you enter your credentials into that one?
Well ... somebody did. That somebody didn't have 2-factor authentication in use. It resulted in similar spam sent to every single person found from address book or recent e-mails. It is yet to be determined, what else happened.
The login screen is a no-brainer: it has no HTTPS enabled, the address bar clearly states something else than Google, there is no way this site was created or endorsed in any way by Google. All the alarms should be ringing when one sees that kind of page ... but no.
And for god's sake: enable the 2FA now! Even this scam would have been prevented if one would have been in use.
