.korea Files Virus – Distribution
The .korea file ransomware is the type of virus, that aims to infect users via a variety of means, including sending the infection directly to victims and also uploading it online, waiting for an infection to happen.
The main idea behind such infection methods is to get victims to fall to the trick, believing what they see is what they were searching for online or some important document concerning them. Usually the most often case is the one with e-mails that are sent directly to victims and these e-mails may have a file, embedded as an attachment, which is the actual infection object.
Files sent via mail could infect as a result of the victim downloading and executing them and the same goes for malicious web links that may also be sent via mail.
Another method that can also be used to infect users could be uploading the infection file on websites, where it may wait patiently to be downloaded by users. These types of files could often end up to be malicious files that pretend to be:
