Facebook has been hit by another scam that exploits the social network's 'Like' button, reports security firm Sophos. The scam, which has been dubbed 'likejacking', updates user profiles with a message saying that the user likes a web page called '101 Hottest Women in the World :D'.Anyone who clicks on the link to investigate what the web page is will be taken to a web page containing a photo of Hollywood starlet Jessica Alba. The page is infected by a Trojan which is identified by Sophos antivirus as Troj/Iframe-ET.The scam works by hiding an invisible button underneath the user's mouse pointer – so if they're logged into Facebook, clicking anywhere on the infected page will update their Facebook profile to say that they also 'Like' the page, before redirecting them to pictures of female celebrities from lad's mag Maxim.
