Short bio

Ransom.Ekans is Malwarebytes’ detection name for a highly targeted ransomware family. This family appears to have a special interest for Industrial Control Systems (ICS).

Type and source of infection

Ransomware is a category of malware that holds files or systems hostage for ransom.
Ransom.Ekans is very likely dropped inside affected networks by using open RDP connections. Once delivered Ransom.Ekans checks whether the system it is running on belongs to a certain domain and if so, it starts encrypting the files on the system.


Malwarebytes detects Ransom.Ekans by by using real-time protection and by using Anti-Ransomware technology.
