Facebook ‘dislike’ scam warning

Facebook users are being targeted in a scam that offers them a chance to install a “dislike” button.

The scam tricks users into allowing a rogue application to access their profile page, which then posts spam messages. It also attempts to lure people into completing an online survey, for which the scammers are paid money. The social network already offers a “like” button that allows people to rate other user’s comments and posts. Graham Cluley of security firm Sophos said it was the latest in a series of “survey scams” that included links to a video purporting to show an anaconda vomiting up a hippo. “One thing we commonly see is that the message starts ‘OMG, shocking video’,” he said. “And they appear to come from your Facebook friend, giving it a ringing endorsement.”Dislike button permission page

Unknown apps

The dislike button scam prompts people to download an application with the message: “Download the official DISLIKE button now.” When users click on the link it prompts them to install a rogue application, which does not function as a dislike button. Once a user has given it permission to access their profile, it updates the user’s page with a link and a message: “I just got the dislike button, so now I can dislike all of your dumb posts lol!!!” “Many people are giving permission for completely unknown apps,” Mr Cluley told BBC News. The surveys appear to be from genuine companies, he said. “As far as we can tell, they appear to be legitimate,” he said. “It could be that the firms are not policing their affiliates properly.” The scam finally points users towards a Firefox add-on that installs a “dislike” button.
