Facebook isn’t doing enough to protect members from a recent spate of clickjacking attacks on the popular social networking site.
That’s the verdict of 95% of the 600 people we polled overnight after the latest attack that struck the social network, tricking users into ‘liking’ a webpage entitled ‘101 Hottest Women in the World’.
The scams, dubbed ‘likejacking’ by Sophos, exploit the ‘Like’ button facility by automatically updating a user’s Facebook status to ‘like’ a third party webpage without the user realising that they have clicked a button at all.
The update is then automatically shared with a user’s Facebook friends via the website’s newsfeed, helping the attacks to spread rapidly across the social network.
Although the attacks are yet to deliver malicious payloads, they demonstrate an exploitable weakness in the way that Facebook works, putting users at potential risk from future malware or phishing attacks.
Facebook clearly hasn’t been security-conscious enough in the implementation of its social ‘Like’ plugin. This leaves the system open to abuse by spammers and scammers, and can expose users to the risk of outside threats.
One solution would be for Facebook to implement ways for members to make a more conscious decision as to whether they want to ‘Like’ third-party content or not. By having a pop-up box asking whether users are sure they want to ‘Like’ a particular page, or offering the option to disable the third-party ‘Like’ feature entirely, the spread of these attacks would be much easier to control.
Furthermore, it’s clear that Facebook needs to set up a proper early-warning system to alert users about breaking threats. It seems wrong that the only place where Facebook users can read about the latest attacks is on the pages run by security vendors on Facebook , rather than Facebook’s own security pages.
