| Name | Type | Associated Threat Actor(s) | Description |
|---|---|---|---|
| DoppelPaymer | Ransomware | Unknown | DoppelPaymer is an emerging type of ransomware that not only locks companies out of their own computer systems by encrypting files—the hallmark of typical ransomware—but also can exfiltrate company data and use it as collateral. |
| Ryuk | Ransomware | Wizard Spider | Similar to Samas and BitPaymer, Ryuk is specifically used to target enterprise environments. Code comparison between versions of Ryuk and Hermes ransomware indicates that Ryuk was derived from the Hermes source code and has been under steady development since its release. Hermes is commodity ransomware that has been observed for sale on forums and used by multiple threat actors. However, Ryuk is only used by WIZARD SPIDER and, unlike Hermes, Ryuk has only been used to target enterprise environments. Since Ryuk’s appearance in August, the threat actors operating it have netted over 705.80 BTC across 52 transactions for a total current value of $3,701,893.98 USD.

| Ragnar Locker | Ransomware | Ragnarok Group | A new ransomware attack method takes defense evasion to a new level—deploying as a full virtual machine on each targeted device to hide the ransomware from view. In a recently detected attack, Ragnar Locker ransomware was deployed inside an Oracle VirtualBox Windows XP virtual machine. The attack payload was a 122 MB installer with a 282 MB virtual image inside—all to conceal a 49 kB ransomware executable. |

| EKANS | Ransomware | EKANS ransomware emerged in mid-December 2019. While relatively straightforward as a ransomware sample in terms of encrypting files and displaying a ransom note, EKANS featured additional functionality to forcibly stop a number of processes, including multiple items related to ICS operations. While all indications at present show a relatively primitive attack mechanism on control system networks, the specificity of processes listed in a static “kill list” shows a level of intentionality previously absent from ransomware targeting the industrial space. |
