Today, I received an email from one of my coworkers (yes, even careful employees of security vendors are in danger:) ). This email has more recipients and contains only one link, without any text or subject.
Fortunately, I am a really paranoid person about emails containing only a link to an unknown site. At this link, you can notice two really suspicious things: The directory is images and there’s a file called yahoo12.php. That should warn users to avoid clicking on this link.
