If you checked in on your Facebook news feed in the last week, you probably noticed your friends were posting a lot of porn. However they weren't putting their adult entertainment preferences on display, they were actually hacked.

The slightly advanced Facebook user (those who have been around long before news feeds and messenger) would have recognized the post from another scam. That's because the recent porn posting spyware used the same method as the Bin Laden spyware back in May.

The spyware appears as a link that your friend shared. Once you click on it and try to open the site, it goes through and posts on your wall, as well as messages your friends. The most recent round included adult themed posts (although I did see the 'big pimple' post this weekend, which is another version of the spyware).

Facebook says most of the posts have been removed, and that no personal data was hacked during the security breach. However they are encouraging people to be vigilant about the links they click. Including those showing extreme violence, gore, or sex.

The sorts of things you'd find on an average trip to 4chan are now just popping up in innocent user's newsfeed...the smut and gore is cutting a wide swath on Facebook. ... Worms and scams aren't uncommon on Facebook, but [this] appears to be of a different magnitude. - Adrian Chen, Gawker

Some internet security experts also think that this weekends hack could also be setting things up for a bigger attack on the social network site.

So be careful about what you click on Facebook. And if one of your buddies is sending you hardcore porn, you might message them to see if it was on purpose. Better to have an awkward conversation than a hacked and inaccessible Facebook account.
