Ranion

MITRE ATT&CK does not currently catalogue Ranion, 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. T1078.002 Domain Accounts Initial AccessPersistencePrivilege EscalationStealth

   What they do: ranion leverages domain accounts harvested from credential dumps to persist and escalate privileges.

   What that means: Adversaries may obtain and abuse credentials of a domain account as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.

2. T1059.001 PowerShell Execution

   What they do: ranion executes malicious commands via PowerShell scripts to stage payloads and manipulate system behavior.

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

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

   What they do: ranion establishes persistence by injecting malicious entries into Windows Registry Run Keys.

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

4. T1685 Disable or Modify Tools Defense Impairment

   What they do: ranion disables security tools by terminating antivirus processes and modifying Windows Defender settings.

   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.

5. T1070.004 File Deletion Stealth

   What they do: ranion deletes Volume Shadow Copies and backup files via vssadmin and file deletion commands.

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

6. T1135 Network Share Discovery Discovery

   What they do: ranion discovers network shares using net view and similar tools to map lateral movement paths.

   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.

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

   What they do: ranion moves laterally across SMB shares to infect additional hosts within the network.

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

8. T1486 Data Encrypted for Impact Impact

   What they do: ranion encrypts victim files using a custom ransomware engine targeting documents and backups.

   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.
