Nothing new here...
I mean, to my knowledge this trick is used all the time and it will continue to be used as long as users don't bother to think their actions over before taking them.
People (should) know that searching for "explicit contents" can end you up on malicious websites which are only after your money. It has been like this forever. So; a juicy chunk of media (picture, movie, etc.) requires you to update your image viewer of movie player? Then why not go to the official website of whatever it is you're using to check for yourself?
Better yet: why not start by opening your picture or movie viewer first and then load your juicy contents instead of mindlessly clicking on whatever it is you downloaded?
Its for this specific reason why I think that Windows made a huge mistake when they started to hide the extensions for known file types. It has become way too easy to spread an executable file while making its icon look as if its simply trying to start a popular image of movie viewer.
Obvious for most of us, usually not so much for your average user:
But you don't even have Photoshop, so why would you think this file would start your image viewer?
I thought that it shipped with one, didn't know it could be a virus...
Stupid? For sure. But just because we understand what is happening here, a lot of users don't.
