N3tworm

MITRE ATT&CK does not currently catalogue N3tworm, 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: n3tworm uses PowerShell scripts to execute malicious commands and deploy ransomware payloads across compromised systems.

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

2. T1106 Native API Execution

   What they do: n3tworm leverages native API calls to interact with Windows services and evade detection during initial execution.

   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: n3tworm modifies registry run keys to ensure ransomware re-executes automatically after system reboots.

   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: n3tworm disables antivirus tools and security software using registry modifications to ensure ransomware operates undetected.

   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: n3tworm deletes Volume Shadow Copies and backup files via command-line tools to prevent data recovery.

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

6. T1003.001 LSASS Memory Credential Access

   What they do: n3tworm accesses LSASS memory to steal credentials for lateral movement and persistence.

   What that means: Adversaries may attempt to access credential material stored in the process memory of the Local Security Authority Subsystem Service (LSASS).

7. T1049 System Network Connections Discovery Discovery

   What they do: n3tworm queries system network connections to identify active communication channels for exfiltration or C2.

   What that means: Adversaries may attempt to get a listing of network connections to or from the compromised system they are currently accessing or from remote systems by querying for information over the network.

8. T1057 Process Discovery Discovery

   What they do: n3tworm discovers running processes and services to identify critical targets for disruption or privilege escalation.

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

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

   What they do: n3tworm moves laterally through SMB shares to compromise additional hosts within the victim network.

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

10. T1486 Data Encrypted for Impact Impact

    What they do: n3tworm encrypts victim files using strong symmetric cryptography, targeting documents and business data for impact.

    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.

11. T1490 Inhibit System Recovery Impact

    What they do: n3tworm invokes system recovery inhibition commands to prevent backup restoration and maximize impact.

    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.
