Faceliker: the malware that changes your likes on facebook

In recent months the number of malware that we are seeing on Facebook is increasing. The security of the social network is more questioned than ever. We have already told you about previous cases as a Trojan. Now, it is a malware called Faceliker. That takes advantage of our profile on the social network.

Faceliker: The malware that changes your "Likes" on Facebook

Faceliker is not a new malware, as it has been active for a long time. But it has gained a lot of activity the past few weeks. In fact, in the second quarter of the year 9% of all malware that exists is Faceliker. This malware usually hides in malicious extensions for major browsers.

How Faceliker works

The user downloads the specific extension and browses regularly. When doing this, the extension will load JavaScript code with which it will “Like” certain content. So what the extension does is change our algorithm to promote. That is, you may be spreading false news or inappropriate content. Without us having done any of that. In fact, without us knowing.

Also, it seems that there are some modules of this malware that steal passwords on Facebook. So the danger is greater. An easy way to see if we are being attacked by this malware is if we notice that a social network, generally Facebook, starts recommending websites or articles that have nothing to do with our interests.

Faceliker generally takes advantage of open sessions on the social network. So with a closed session you will not be able to act. But, the best way to avoid this malware is having the maximum possible control over our extensions. Since that is where the problem lies.
