Settra

MITRE ATT&CK does not currently catalogue Settra, 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: settra executes malicious payloads through PowerShell scripts to deploy ransomware binaries and evade host-based detection.

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

2. T1685 Disable or Modify Tools Defense Impairment

   What they do: settra disables security tools by terminating antivirus processes and modifying Windows Defender service configurations on targeted engineering workstations.

   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.

3. T1070.004 File Deletion Stealth

   What they do: settra deletes Volume Shadow Copies and backup directories via vssadmin commands to prevent recovery from manufacturing server snapshots.

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

4. T1049 System Network Connections Discovery Discovery

   What they do: settra discovers system network connections to identify high-value engineering servers and isolate compromised retail environments.

   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.

5. T1083 File and Directory Discovery Discovery

   What they do: settra uses file and directory discovery via PowerShell to enumerate critical business documents and backups across manufacturing networks.

   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.

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

   What they do: settra moves laterally through SMB/Windows Admin Shares using stolen credentials to compromise retail and finance systems across corporate networks.

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

7. T1560.001 Archive via Utility Collection

   What they do: settra archives sensitive operational data using built-in utility commands prior to encryption to maximize financial theft impact.

   What that means: Adversaries may use utilities to compress and/or encrypt collected data prior to exfiltration.

8. T1486 Data Encrypted for Impact Impact

   What they do: settra encrypts victim data using custom symmetric encryption routines targeting engineering CAD files and financial ledgers before demanding ransom.

   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. T1490 Inhibit System Recovery Impact

   What they do: settra inhibits system recovery by corrupting Windows restore points and disabling automated backup restoration processes on finance endpoints.

   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.
