Lunalock

MITRE ATT&CK does not currently catalogue Lunalock, 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: lunalock executes malicious commands via PowerShell scripts to stage ransomware deployment and evade detection.

   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: lunalock leverages registry run keys to maintain persistence across reboots and repeated attacker access.

   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: lunalock disables antivirus tools and security software to prevent system recovery and hinder incident response.

   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: lunalock encodes victim files with custom symmetric encryption to ensure data remains inaccessible without payment.

   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: lunalock deletes Volume Shadow Copies and backup files via system commands to eliminate recovery options.

   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: lunalock scans network shares using native tools to identify victim systems 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.

7. T1486 Data Encrypted for Impact Impact

   What they do: lunalock encrypts victim files and data using its ransomware payload to demand payment for decryption keys.

   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.

8. T1490 Inhibit System Recovery Impact

   What they do: lunalock intentionally disrupts system recovery processes and backups to maximize operational disruption.

   What that means: Adversaries may delete or remove built-in data and turn off services designed to aid in the recovery of a corrupted system to prevent recovery.
