Dataleak

MITRE ATT&CK does not currently catalogue Dataleak, 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: dataleak executes PowerShell scripts to stage ransomware payloads and manipulate system processes.

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

2. T1106 Native API Execution

   What they do: dataleak leverages native API calls to interact with Windows services and evade detection.

   What that means: Adversaries may interact with the native OS application programming interface (API) to execute behaviors.

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

   What they do: dataleak modifies Registry Run Keys to ensure ransomware execution upon system startup.

   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: dataleak disables antivirus tools and modifies security software to ensure ransomware execution.

   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. T1027.013 Encrypted/Encoded File Stealth

   What they do: dataleak encodes victim data with custom encryption routines before exfiltration or ransom deployment.

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

6. T1070.004 File Deletion Stealth

   What they do: dataleak deletes Volume Shadow Copies and backup files via command-line tools to prevent recovery.

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

7. T1018 Remote System Discovery Discovery

   What they do: dataleak performs remote system discovery to identify network shares and vulnerable hosts for lateral movement.

   What that means: Adversaries may attempt to get a listing of other systems by IP address, hostname, or other logical identifier on a network that may be used for Lateral Movement from the current system.

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

   What they do: dataleak uses SMB/Windows Admin Shares to propagate ransomware across compromised network segments.

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

9. T1486 Data Encrypted for Impact Impact

   What they do: dataleak encrypts victim files using strong symmetric cryptography to hold data hostage.

   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.

10. T1491.001 Internal Defacement Impact

    What they do: dataleak performs internal defacement by altering system files and displaying ransom notes on victims' machines.

    What that means: An adversary may deface systems internal to an organization in an attempt to intimidate or mislead users, thus discrediting the integrity of the systems.
