Trojan.FBFraud.A is a dangerous Trojan that propagates on Facebook. Trojan.FBFraud.A spreads through a website injected with an obfuscated JavaScript with the aim of downloading a malicious plugin on the PC users' affected computers. Cybercriminals offer affected computer users a rose-pink Facebook theme by urging website visitors to install a plugin first, which is detected as Trojan.FBFraud.A, and will only work in Chrome and Mozilla Firefox web browsers. Users of other web browsers will evade Trojan.FBFraud.A and will be taken to a blank page. Once the plugin is installed, if the PC user is logged into his/her Facebook account, the obfuscated JavaScript will supposedly like the hijacked website on behalf of the user. A link included in the hijacked website is shown on the user's wall, spreading Trojan.FBFraud.A to other Facebook friends, but not before it has offered the pink do-over to the user’s social networking account. This will work as an enticement for the affected user's contact list. The aim is to fool as many computer users as possible into clicking the link, getting compromised and acting as vectors for the malicious website.
