DarkSide is a ransomware threat that has been in operation since at least August 2020 and was used in a cyberattack against Georgia-based Colonial Pipeline, leading to a major fuel supply disruption along the East Coast of the US. The malware is offered as a service to different cybercriminals through an affiliate program and, like other prolific ransomware threats, employs double extortion that combines file encryption with data theft and is deployed on compromised networks using manual hacking techniques.
