Dharma

According to MalwareBytes, the Dharma Ransomware family is installed manually by attackers hacking into computers over Remote Desktop Protocol Services (RDP). The attackers will scan the Internet for computers running RDP, usually on TCP port 3389, and then attempt to brute force the password for the computer.

Once they gain access to the computer they will install the ransomware and let it encrypt the computer. If the attackers are able to encrypt other computers on the network, they will attempt to do so as well.
