There is a new kind of malware spreading on Facebook. This type op malware is hidden in a MacDonald’s giftcard. This malware is dangerous because it takes control of your Facebook account and posts comments in your name .
The malware installs rogue applications to the Facebook profile. Victims will see their account used to spread the fake promotion and after installing the apps that promise them gift cards they are prompted to participate in several offers which require personal credentials.
Some users are prompted to download questionable tool bars, games, or other software. And others are asked for their mobile phone numbers in order to obtain the nonexistent gift cards, only to find themselves subscribed to expensive text-messaging services.
