Rransom

MITRE ATT&CK does not currently catalogue Rransom, so this is our assessment of the techniques it uses, drawn from public reporting. The techniques themselves, and every "what that means" definition below, come from MITRE ATT&CK v19.2. Confidence: medium. Treat it as orientation, not attribution.

1. T1059.001 PowerShell Execution

   What they do: ransom uses PowerShell scripts to execute malicious commands and spread payloads across compromised hosts.

   What that means: Adversaries may abuse PowerShell commands and scripts for execution.

2. T1547.001 Registry Run Keys / Startup Folder PersistencePrivilege Escalation

   What they do: ransom adds malicious registry run keys to ensure persistence across reboots on compromised systems.

   What that means: Adversaries may achieve persistence by adding a program to a startup folder or referencing it with a Registry run key.

3. T1685 Disable or Modify Tools Defense Impairment

   What they do: ransom disables security tools by modifying Windows Defender and AV processes to prevent detection and recovery.

   What that means: Adversaries may disable, degrade, or tamper with security tools or applications (e.g., endpoint detection and response (EDR) tools, intrusion detection systems (IDS), antivirus, logging agents, sensors, etc.) to impair or reduce visibility of defensive capabilities.

4. T1036.005 Match Legitimate Resource Name or Location Stealth

   What they do: ransom masques its malicious binary as svchost.exe to evade process-based detection tools.

   What that means: Adversaries may match or approximate the name or location of legitimate files, Registry keys, or other resources when naming/placing them.

5. T1070.004 File Deletion Stealth

   What they do: ransom deletes Volume Shadow Copies and backup directories via command-line tools to eliminate recovery options.

   What that means: Adversaries may delete files left behind by the actions of their intrusion activity.

6. T1049 System Network Connections Discovery Discovery

   What they do: ransom enumerates system network connections to identify active hosts and establish command-and-control channels.

   What that means: Adversaries may attempt to get a listing of network connections to or from the compromised system they are currently accessing or from remote systems by querying for information over the network.

7. T1057 Process Discovery Discovery

   What they do: ransom discovers running processes to identify critical services and disable them to maximize disruption.

   What that means: Adversaries may attempt to get information about running processes on a system.

8. T1135 Network Share Discovery Discovery

   What they do: ransom probes network shares using SMB enumeration to identify additional victims for lateral movement.

   What that means: Adversaries may look for folders and drives shared on remote systems as a means of identifying sources of information to gather as a precursor for Collection and to identify potential systems of interest for Lateral Movement.

9. T1021.002 SMB/Windows Admin Shares Lateral Movement

   What they do: ransom leverages SMB/Windows Admin Shares to move laterally between networked machines.

   What that means: Adversaries may use Valid Accounts to interact with a remote network share using Server Message Block (SMB).

10. T1486 Data Encrypted for Impact Impact

    What they do: ransom encrypts victim files using its own encryption engine, targeting documents and system data for impact.

    What that means: Adversaries may encrypt data on target systems or on large numbers of systems in a network to interrupt availability to system and network resources.
