Gammax

MITRE ATT&CK does not currently catalogue Gammax, 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: Gammax executes malicious commands through PowerShell scripts to deploy payloads and maintain access.

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

2. T1112 Modify Registry PersistenceDefense Impairment

   What they do: Gammax modifies Windows Registry Run keys to ensure ransomware execution on reboot.

   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: Gammax disables security tools by terminating antivirus processes and modifying Windows Defender settings.

   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. T1070.004 File Deletion Stealth

   What they do: Gammax deletes Volume Shadow Copies and backup files via vssadmin to prevent recovery.

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

5. T1049 System Network Connections Discovery Discovery

   What they do: Gammax discovers system network connections using netstat to identify high-value targets for encryption.

   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.

6. T1083 File and Directory Discovery Discovery

   What they do: Gammax uses file and directory discovery via PowerShell to enumerate critical data paths before encryption.

   What that means: Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system.

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

   What they do: Gammax leverages SMB/Windows Admin Shares for lateral movement across networked construction and logistics systems.

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

8. T1486 Data Encrypted for Impact Impact

   What they do: Gammax encrypts victim files using custom ransomware binaries targeting IT and real estate data directories.

   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.

9. T1489 Service Stop Impact

   What they do: Gammax stops critical Windows services like backup agents and monitoring tools via net stop commands.

   What that means: Adversaries may stop or disable services on a system to render those services unavailable to legitimate users.

10. T1490 Inhibit System Recovery Impact

    What they do: Gammax inhibits system recovery by corrupting backup infrastructure and disabling restore services.

    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.
