The latest threat encircling Facebook is a rogue application dubbed "Distracting Beach Babes." The application compromised the security of thousands of users' accounts by way of status messages that appear to be from friends but when the users click through on the link, they're asked to give an application permission to run. The app then tells users they must update their "FLV player" before they can see the video. Those who attempt to do so are redirected to another page where malware is installed on their computer.
This is hardly the first rogue application to take advantage of Facebook's automated app approval systems. In fact, only days ago, a similar attack take place. This one was a link to what was purportedly the "sexiest video ever!".
This particular application led to a very busy weekend for anti-virus firms, indicating a major push by rogue Facebook apps. There anti-malware software blocked more than 30,000 rogue Facebook applications, more than three times the rate of rogue anti-spyware.
In other words, the new anti-malware wave won't be coming from email, IM or other random websites users are tricked into visiting. It will come from your Facebook friends.

Due to frequent attacks of viruses on social networking sites, Facebook has decided to increase its security level for its users. Facebook is trying not only to protect the privacy of its users but also wants to provide security against malicious threats, like viruses, spyware and spam.
The pressure on social networking sites to take action on the security front comes increasingly from parents who are concerned about their children’s online security. In the recent statement Facebook they will be creating a special support team that will provide guidance to parents on how to maintain security level for their child while they are using Face book.
However many technocrats are worried about hackers who sends unprecedented spam to more than 400 million registered users. Experts want Facebook to have more resistive security protocol measures in order keep a check on spammers.
Facebook claims that it has introduced new era of technology measures such as CAPTCHAs (Completely Automated Public Turing tests to tell Computers and Humans Apart), which is an automated computer application that runs on the server. If the application detects that a particular users is sending message in an erroneous manners, it will instantaneously block that user.
