Unknown

MITRE ATT&CK does not currently catalogue Unknown, 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: low. Treat it as orientation, not attribution.

1. T1059.001 PowerShell Execution

   What they do: unknown uses PowerShell scripts to execute malicious commands and payload deployment 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: unknown modifies registry run keys to ensure malware execution upon system startup for persistence.

   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: unknown disables security tools and monitoring agents to prevent detection and hinder incident response efforts.

   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. T1027.013 Encrypted/Encoded File Stealth

   What they do: unknown encodes victim data before exfiltration to protect stolen information from analysis and detection.

   What that means: Adversaries may encrypt or encode files to obfuscate strings, bytes, and other specific patterns to impede detection.

5. T1070.004 File Deletion Stealth

   What they do: unknown deletes Volume Shadow Copies and backup files via vssadmin to eliminate recovery options for victims.

   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: unknown performs network share discovery to identify accessible remote directories for lateral movement and data targeting.

   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. T1560.001 Archive via Utility Collection

   What they do: unknown archives victim data using utility commands prior to exfiltration to preserve evidence for ransom demands.

   What that means: Adversaries may use utilities to compress and/or encrypt collected data prior to exfiltration.

8. T1486 Data Encrypted for Impact Impact

   What they do: unknown encrypts victim files using strong symmetric encryption to maximize impact and trigger ransom demands.

   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.
