description: |
Detects specific windows registry modifications made by BlackByte ransomware variants.
BlackByte set three different registry values to escalate privileges and begin setting the stage for lateral movement and encryption.
This rule triggers when any of the following registry keys are set to DWORD 1, however all three should be investigated as part of a larger BlackByte ransomware detection and response effort.
