Dharma, first known as CrySiS, is a long-running Windows ransomware-as-a-service family. Most builds rename files to .id-[ID].[email].[ext], where the last part changes between variants, and leave notes such as FILES ENCRYPTED.txt or info.hta. Affiliates usually enter through RDP, steal passwords with a scripted toolkit and spread to servers and shared folders, mostly at small and mid-sized firms. No leak site is tied to the family. CrySiS relaunched as Dharma in late 2016 after its master keys were posted publicly, and its code has since passed to many operators.
