Clickjacking Worm Exploits Facebook "Like" Feature

An anonymous reader writes "For the last 24 hours, a series of attacks have exploited Facebook's 'Like' feature through a clickjacking vulnerability. Using subjects such as 'This Girl Has An Interesting Way Of Eating A Banana, Check It Out!' hackers have spread an attack that links to web pages that use invisible iFrames to trick users into saying they like the content. Users are presented with a innocent-seeming web page that says 'Click here to continue,' but clicking at any point on the page publishes the same message to their own Facebook page. Security blogger Graham Cluley says that hundreds of thousands of Facebook users have been hit, and offers advice on how to clean up affected Facebook profiles.

      That's a great quote, so I kind of feel like a bastard for spoiling it, but... P2P programs generally recognise identical files by their hash value; so if the guy simply renamed some files that were already out there under their original name, they'd have used his copy for certain parts, even if people didn't search under it for that name.

      Sometimes, stupid things are funny. I don't live in a bubble, and if my friends think something stupid is funny or interesting, I want to see it, because I care about what my friends think and because I find value in sharing an experience and because it might actually be worth my time.

      I don't have to use Facebook, but it's how a lot of my friends choose to communicate, and my social life is healthier because of it. Many of them aren't geographically close enough to see them in person often, and those that are don't always have a compatible schedule, so Facebook allows me to stay in contact with people I wouldn't otherwise be able to (indeed, I've reconnected with people on Facebook that I haven't seen in over a decade, who are on the other side of the globe).

      I think it's reasonable to expect that when I click a link to a web page, nothing bad should happen to me. In fact, nothing did happen - I'm not sure if that's because Facebook has already blocked this, or my browser has built-in security measures in place to prevent it, or (more likely) the exploit failed due to some bug or incompatibility. I looked at the HTML, saw what it was trying to do, saw that it was malicious, and went no further. That's how I WANT things to work.

    The real problem isn't as much of an exploit so much as it is Facebook's platform for cross-site publishing is basically broken. They allow any site to act as the user with no confirmation other than a click, which as we've seen is easy to get via an invisible iFrame that follows the mouse. Aside from revamping the way they handle "Likes" and other such things on other sites, there's not much they can do to "fix" it.

    Out of curiosity, I opened the link in a separate browser without my Facebook login. It would then try to do a "security check" in which you have to answer a survey to prove that you're human. Being the smart Slashdotters we are, we know Captchas are how it's done. The main take-away: (1) Hover, look, and think before you click and (2) If the link goes outside Facebook, it is SPAM and should be reported.
