A ransomware disguised as an image file (.jpg) on ​​Facebook, LinkedIn, and other social networks.

Checkpoint researchers recently discovered that cyber crooks can embed malware into graphics and image, and how they can perform it code within these to infect social network users with variants of the dangerous Locky ransomware.

"The attackers are taking advantage of a configuration error in the social media infrastructure to force their victims to download the image file. "As a result, users' devices become infected after a single click on the file," the researchers said.Ransomware virus

Checkpoint called the ImageGate carrier attack, and offered that information had been collected on Facebook and LinkedIn since early September.

But as it seems the with ransomware continue unabated which means that social networks have not patched the security gap that allows them.

As long as they are looking for a solution, the CheckPoint research team advises you not to open a picture from another user and not download them to your computer.

"Every social networking site should display the image without having to download it," say the researchers, so you do not need to open the image file.

Η CheckPoint also advises users not to open any image files with unusual (eg SVG, JS or HTA).

The good news is that this attack has not been automated. That is, it requires users to download and run the malicious files themselves. The bad news is that there is always someone who opens the files that come to him, especially if it is a "harmless" image.
