Clickjacking Worm Exploits Facebook "Like" Feature 124

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.

        • So...
          Couldn't one just find out the hash values of the pieces of the files they are downloading and generate random data until the hash value matches?

      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/ [noscript.net] :

        A similar technique for Privoxy users can be found here: http://bmearns.net/wwk/view/Privoxy [bmearns.net]

        By default it only stops cookies. At the bottom of the page it is explained how to block all Facebook access from third party sites.

        That should ensure that content from both domains will work together on the Facebook site itself... I’ll have to wait until I get home to actually test them, though.

        (I knew facebook.com obviously but I also knew there was a 2nd domain that I didn’t remember off the top of my head.)

      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.

      • > I think it's reasonable to expect that when I click a link to a web page,
        > nothing bad should happen to me.

        Why not shorten that to "I think it's reasonable to expect that nothing bad should happen to me"?

              Some do use IM, which is fine if they happen to be online at precisely the same moment I am. And they generally can all receive e-mail, but they wouldn't send me e-mail for anything that wasn't really important; for just generally staying in touch it's not the medium of choice.

              I know, it seems crazy, because e-mail is such a huge part of our lives, but the unenlightened see things differently.

      • I think it's reasonable to expect that when I click a link to a web page, nothing bad should happen to me.

        It partially depends on what your idea of “bad” is. A line gets posted to your news feed saying that you “like” something. That could be mildly embarrassing but it’s not bad to the same degree as getting your computer rooted or stepping off the curb and getting hit by a truck.

  • I encountered this on Facebook a few minutes before seeing it on Slashdot. I'm not sure why, but it didn't work for me. Does Safari have any sort of built-in protections against this sort of thing? Or has Facebook blocked it already? Or did it just not work due to a bug somewhere?

  • I saw a lot of my friends get hit by something just like it, including a rick-roll. Every one of them said they didn't click "like" on the rick-roll site, but it showed up as a like on facebook anyway. Who wouldn't be curious enough to want to click on a "FriendX likes you. [example.com]" link? Thankfully I have a habit of checking the URLs on unusual facebook links. The strange part was there were many different URLs for the "you", so it looked like a "distributed" attack (FB couldn't just search for one URL).

    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.

  • While opening a bunch of feed items (including this one) which included several different websites, I was prompted to download "like.php" which is a kind of thing that happens when websites set bad headers...

    None of my tabs failed to load, so I'm guessing this came from a rogue advert (?)

    I don't have a facebook account though, so I'm not worried.

  • They could have combined it with the "history stealing" exploit [asp.net], registered domains bananas.com [slashdot.org] and peaches.com [slashdot.org], and picked for each victim the "appropriate" site to like.
  • It is also worth pointing out another Facebook exploit which allows a page to 'run' Javascript on a Facebook page. It prompts the user to perform certain actions which copy-and-paste a 'javascript:' style URL to the address bar, and to click Enter to execute the Javascript. This also has the potential to spread fast by sharing it with all of your friends. See http://infinity-infinity.com/2010/05/facebook-exploit-social-engineering-javascript-injection/ [infinity-infinity.com].
  • To solve problems like this. No matter what Mark Z decides to Zuckerpunch my privacy settings into tomorrow or the next time he secretly changes them, or not matter what bullshit he opts me into, the rest of my webbrowsing (slashdot and wikipedia) will remain separate from FB's braindead "features".

    I already removed almost all my personal info of course, but facebook is simply too big to close completely. It would close off a useful service. Again, it's not that I object to FB trying to make a profit to sup
