Introduction
Dharma is a prolific ransomware family active since at least 2016, evolving from the earlier CrySiS ransomware. It operates under a Ransomware-as-a-Service (RaaS) model, allowing affiliates to deploy customized builds with their own contact emails and extensions. Dharma typically appends encrypted files with patterns like .id-[victimID].[email].dharma or other campaign-specific suffixes. Initial access is often gained through exposed Remote Desktop Protocol (RDP) services secured with weak or stolen credentials, sometimes combined with brute-force attacks. The malware encrypts files using AES with RSA to secure the keys and drops ransom notes in text files and pop-up windows. Numerous variants have emerged over time, each linked to different affiliates, making attribution difficult.
