What is KillRabbit ransomware

KillRabbit is a cryptovirus that encrypts user files with AES algorithm, adding .killrabbit as an extension to these files. The executive file is killrabbitV2-release.

However, below we list some PHP files from the website of the attackers, which contain some information.
