Freecivilian

MITRE ATT&CK does not currently catalogue Freecivilian, 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: freecivilian executes malicious commands via PowerShell scripts embedded in its deployment chain.

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

2. T1112 Modify Registry PersistenceDefense Impairment

   What they do: freecivilian modifies registry run keys to ensure recurring execution after reboots.

   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: freecivilian disables host defenses by modifying security tool configurations and service behaviors.

   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: freecivilian deletes backup files and Volume Shadow Copies to prevent recovery.

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

5. T1135 Network Share Discovery Discovery

   What they do: freecivilian scans network shares to identify additional victim systems for lateral propagation.

   What that means: Adversaries may look for folders and drives shared on remote systems as a means of identifying sources of information to gather as a precursor for Collection and to identify potential systems of interest for Lateral Movement.

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

   What they do: freecivilian moves laterally through SMB/Windows Admin Shares to compromise additional hosts.

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

7. T1567.002 Exfiltration to Cloud Storage Exfiltration

   What they do: freecivilian exfiltrates sensitive victim data before demanding payment for decryption keys.

   What that means: Adversaries may exfiltrate data to a cloud storage service rather than over their primary command and control channel.

8. T1486 Data Encrypted for Impact Impact

   What they do: freecivilian encrypts victim files using its own ransomware payload 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.

9. T1489 Service Stop Impact

   What they do: freecivilian stops critical services and processes to disrupt victim operations before encryption.

   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: freecivilian disrupts system recovery by blocking volume shadow copy restoration processes.

    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.
