What you should know about Koobface scam:
Koobface is a malicious program that is capable of affecting Mac OS X, Linux and Microsoft Windows operating systems. Koobface is also known as W32/Koobface, W32/Koobface.AZ, W32.Koobface and Boface. By the time it gets on a machine, it checks if there are cookies of social networks. If it finds the cookies, it infects victim’s profile. Koobface worm is usually spread on these social networks: MySpace, Facebook, Yahoo Messenger, Skype, and Twitter. If Koobface worm can’t find evidence of social networking websites, it simply erases itself and then loads pop-ups that look like MS Windows error messages. The pop-ups contains the following text: “Error installing Codec. Please contact support.”
If computer user actively uses social media networks, Koobface detects particular cookies and collects victim's login information of all social media websites that he or she visits. Then it sends messages to people on the victim's friend list, asking to view a video. This message includes a malicious hyperlink. If people click on this hyperlink, they are going to be redirected to a harmful website, which states that an update of Flash is required in order to review the content. The download links includes flash_player.exe file. If the person allows to install the update, he/she gives an access for an installer of Koobface. It means that this .exe file is going to silently download and install Koobface infection files.
Koobface hacking worm allows the cyber-criminals to track and record sensitive data about the victim, for example, it can see what passwords do you enter on particular websites, what are your logins and it can even find out credit card info and banking information! Be aware because it can lead to a financial loss. In addition to that, this malicious worm can display vague ads convincing you to install fake anti-virus programs. Do not install any software promoted by Koobface virus hoax - most likely you will infect your computer even more.
How Koobface can hijack my computer?
Koobface is usually spread via social engineering. It means that it is spread via social media messages. If your friend has sent you a link that looks suspicious (looks unfamiliar and contains a lot of random symbols), you should double-ask your friend if he/she really sent that. Such Koobface spam usually includes such and similar lines:
- "I saw your silly face in that movie, check it!";
- "Why do you look so stupid? xD See yourself";
- "You look just awesome in this new movie";
- "My friend caught you on hidden cam."
What you can do to secure your computer from this worm?
- Do not browse unreliable websites. If you have opened a website which asks to update your Flash Player, and you know that it was possible to open other videos before, you should know that the website is suspicious. Close it immediately.
