- A malicious file attachment masked as a legitimate document and uploaded in a .rar or .zip archive. Such a file could be set to evade detection and this way tricks you into allowing the ransomware to start on your PC.
As reported by users infected by .KEYRASS ransomware some of the products uploaded on the malicious website cracksfiles.com are also set to distribute the infection files of the threat. Eventually, once opened on a computer, files downloaded by this website infect it with the ransomware.

Once all malicious files are established the ransomware is ready to implement some changes that ensure its persistent presence on the system. These changes mostly affect the registry sub-keys Run and RunOnce. This could be explained by the fact that these keys manage the automatic execution of all essential files and objects that support the normal system load on its start. By manipulating their functionalities .KEYPASS virus takes the advantage to execute automatically its malicious files on each system start. Which in turn leads to the corruption of all files created before the last system shut down.
