Darkside is a type of ransomware that targets organizations by encrypting their data and demanding a ransom for its release. It gained notoriety in 2020 for its sophisticated attacks and the use of a double extortion model, where attackers not only encrypt files but also threaten to leak sensitive information if the ransom is not paid. The Darkside group operates as a ransomware-as-a-service (RaaS), allowing other cybercriminals to use their tools and infrastructure for a share of the profits. This model has contributed to a rise in ransomware attacks, impacting various sectors and prompting increased cybersecurity measures across industries.
