Thousands of Facebook users are falling for software which claims to stick a “dislike” button in the social notworking site but instead shoves in malware.
Computer security firm Sophos pointed out that there was no "Dislike" version of the "Like" icon and anyone installing an application pitched as a "Dislike" button that jokingly notifies contacts at the social networking service "now I can dislike all of your dumb posts" is malware.
Once granted permission to access a Facebook user's profile, the application pumps out spam from the account and spreads itself by inviting the person's friends to get the button, according to Sophos.
Facebook appears to be a jolly good target for hackers at the moment. Perhaps it is because it is mostly full of people who don't really care that much about sticking their private data online (Don't you have a Facebook page? sub.ed.)
