What is Koobface?
Back in 2008, messages sent through popular social media programs and through major email websites became infected with malware that came to be known as the Koobface virus.
Koobface is a virus used to target Windows, Mac and Linux operating platforms intended to infect your computer with malware.
How does Koobface work?
Koobface spreads through social networking sites.
Once the Koobface worm has infected its targeted system, it uses the infected computer to replicate itself.
One typical way for it to infect a computer is through malicious links which send a victim to a fake website that might look like a Facebook video page or a YouTube account.
The victim tries to watch the video, but first receives a warning that, in order to do so, a “Flash” update is required.
But that Flash upgrade is really just the Koobface virus installer being disguised.
When it first began to spread, it often used email subjects such as, “You look just awesome in this new movie.”
It would then provide the email recipient with a link to the supposed video file that led them to the fake request to update Flash.
What does Koobface do?
An infected computer will then begin to reach out to other infected computers to build a larger network.
The worm is technically a “bot.”
Once a cybercriminal has accessed targeted systems, he or she can begin to access sensitive information such as a bank account number, passwords and usernames, credit card numbers and more.
But aside from garnering private information, hackers who use the Koobface worm can also place other forms of malicious programs on the infected computer.
How do I detect and remove Koobface files?
Start by scanning your computer with a highly rated anti-virus program.
Some programs may be able to detect the malicious files and remove them.
Be sure to keep your security programs up to date, as the Koobface file often change and find new ways to go undetected.
While manual methods of removal do exist, it’s best to allow a professional to handle that matter.
Trying to remove malicious files could result in damage to other necessary files, or even the loss of your documents.
What should I do now?
Because Koobface may have allowed hackers to see your username and passwords, it’s also a good idea to change your passwords for all online accounts.
Be sure to monitor your monthly bills and your bank statements for any unauthorized activity.
To avoid an infection, avoid downloading a video player or any other file when a website recommends you do so.
Verified, safe sites should provide information on what software is needed, and you can then seek out that file from a trusted source.
When you’re using social media, don’t get sucked into clicking on random links.
If you aren’t sure of a link’s intent or source, it’s best to avoid it, no matter what interesting story or video it promises to provide.
