Sovcali

MITRE ATT&CK does not currently catalogue Sovcali, 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: Sovcali executes malicious payloads through PowerShell scripts to stage ransomware binaries across engineering networks.

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

2. T1685 Disable or Modify Tools Defense Impairment

   What they do: Sovcali disables security tools by terminating antivirus processes and modifying Windows Defender service configurations.

   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: Sovcali deletes Volume Shadow Copies and backup directories via vssadmin commands to prevent recovery.

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

4. T1083 File and Directory Discovery Discovery

   What they do: Sovcali uses file and directory discovery via PowerShell to enumerate critical business documents and backups on manufacturing systems.

   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.

5. T1486 Data Encrypted for Impact Impact

   What they do: Sovcali encrypts victim files using custom ransomware binaries targeting manufacturing engineering data repositories.

   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.

6. T1490 Inhibit System Recovery Impact

   What they do: Sovcali inhibits system recovery by corrupting restore points and disabling backup service restoration 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.
