What it detects

This rule detects the ransomware stage of the multi stage campaign which appends the @NeverMind12F extension to encrypted files and drops a ransom note that carries a distinctive Cyrillic file name. Creation of files with this extension or note name indicates encryption in progress. The variant derives from the Hakuna Matata family.
