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.

    I hate posts without proper links...
    So, who will post the direct link to the girl with an interesting way of eating a banana?

    Thank you NoScript for stopping this for me. I knew it looked "phishy."

      Better yet, use NoScript's ABE facility to block any non-Facebook web page from loading a Facebook page or API. From http://noscript.net/abe/ :

      # This one allows Facebook scripts and objects to be included only
      # from Facebook pages
      Site .facebook.com .fbcdn.net
      Accept from .facebook .fbcdn.net

      Here's the line from my unbound.conf that solves all Facebook related problems for me:
      local-zone: "facebook.com." static
      followed by no local-data lines.
      I see "address not found" error messages on lots of web pages: Facebook iframes are freaking everywhere. No more.

    Here. I'll offer the simplest advice you can get: Stop clicking on stupid shit.

    Just by doing that, internet/computer security would be vastly improved.

    Eh. The scammers use "stupid shit" as the bait because that's what works. If "intelligent shit" started attracted the most clicks, they'd start using that instead.

    Once a single mouse click on an infected link is enough to propagate the link, it's already game over--the choice of bait is a detail.

    Why does the Slashdot section on worms have a picture of a crawling caterpillar?

    They do it just to bug people ;-)

    You mean "This New Intel CPU Has A Great New Hologram! Check It Out!" won't 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.

    OK I'm all confused now. Just answer the question, is "Why Apple Is So Sticky" safe to click on or not?

    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.
