Lockdata

MITRE ATT&CK does not currently catalogue Lockdata, 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: lockdata leverages PowerShell to execute malicious commands and stage ransomware payloads across compromised systems.

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

2. T1112 Modify Registry PersistenceDefense Impairment

   What they do: lockdata modifies registry run keys to ensure ransomware execution persists across system reboots.

   What that means: Adversaries may interact with the Windows Registry as part of a variety of other techniques to aid in defense evasion, persistence, and execution.

3. T1685 Disable or Modify Tools Defense Impairment

   What they do: lockdata disables security tools like antivirus software and monitoring agents to evade detection and persistence.

   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 Obfuscated Files or Information Stealth

   What they do: lockdata obfuscates its own binaries and configuration files using custom encoding to avoid static detection.

   What that means: Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.

5. T1070.004 File Deletion Stealth

   What they do: lockdata performs file deletion to remove backups, Volume Shadow Copies, and recovery artifacts before encryption.

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

6. T1057 Process Discovery Discovery

   What they do: lockdata uses process discovery to identify critical system processes before targeting or terminating them.

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

7. T1486 Data Encrypted for Impact Impact

   What they do: lockdata encrypts victim files using a custom ransomware payload, locking data for extortion 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.

8. T1490 Inhibit System Recovery Impact

   What they do: lockdata executes scripts to inhibit system recovery processes, preventing automatic backups or restore mechanisms.

   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.
