Detecting DarkSide ransomware

 

DarkSide ransomware presents users on targeted machines with a customized URI that contains their leaked information. The payload leaves machines at a minimum level of operation, only enough to browse the attackers' websites to gather required information to make payment to the attackers.

You are an analyst responsible for your organization's overall security posture. You need to be able to detect and investigate unusual activities that might relate to DarkSide ransomware, and these searches help you to do that.
