What’s this? A random post dangling genuinely free porn in yourFacebook feed? Think twice before clicking on it, because there’s no happy ending in sight if you do.

I know, Geek readers, you’re positively shocked that something popping up in Facebook feeds like crazy is actually a hoax. It’s hard to believe, but it does happen. It’s also hard to imagine anyone thinking that clicking on anything porn-related on Facebook would ever be a good idea.

But clearly someone does, which is amazing. Even if there was real porn waiting for your mouse click to kickstart the action, you’re still running the risk of broadcasting what you’re doing to anyone you’re friends with — which is exactly what’s happening with this new attack. Once a victim clicks through they unwittingly tag their friends and send an invite to the peep show.

This latest scam takes a more subtle approach to propagation than other Facebook malware the experts have seen. Similar stunts have relied on sending bogus messages from the victim to his or her friends. A simple tag is much more cunning. There’s no awkwardly-worded message to tip another user off, just a simple, harmless-looking tag. Pique their interest and entice the initial click, then hope that the new target can’t resist finding out what it is that their friend just had to watch.

Oh, but wait… you can’t watch this porn because you’re plug-in is out-of-date! No worries, a couple more clicks will ensure that you’re properly taken care of. Commit this to memory, Facebook users: any video that demands you install or update a plug-in before viewing it? It’s probably a Trojan. There are much better (and safer… and less public) places to look for porn than Facebook.
