'Clickjacking' worm hits hundreds of thousands on Facebook

'This girl gets OWNED.' And you can too

A vulnerability on Facebook forced hundreds of thousands of users to endorse a series of webpages over the holiday weekend, making the social networking site the latest venue for an attack known as clickjacking.

The exploit works by presenting people with friend profiles that recommend — or "Like," in Facebook parlance — links with titles including "LOL This girl gets OWNED after a POLICE OFFICER reads her STATUS MESSAGE." Those who click on the link see a page that's blank except for the words "Click here to continue." Clicking anywhere on the page automatically forces the person to add the link to his list of Likes.

Clickjacking is a term that was coined in late 2008 by web application security researchers Jeremiah Grossman and Robert "RSnake" Hansen. It describes attacks that allow malicious website publishers to control the links visitors click on. Virtually every browser is vulnerable, although many browsers come with safeguards that can make exploitation harder.

The Facebook worm that hit over the weekend superimposes an invisible iframe over the entire page that links back to the victim's Facebook page. As a result, as long as the person is logged in, his profile automatically recommends the link to new friends as soon as the page is clicked on.

Twitter was attacked by a series of clickjacking exploits last year that forced users to publish tweets against their will. The exploits stopped after company engineers finally tightened down their site. Facebook engineers will undoubtedly follow suit, if they haven't already. But this isn't the first time Facebook has been hit by clickjacking.
