Goznym

MITRE ATT&CK does not currently catalogue Goznym, 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: goznym executes ransomware payloads via PowerShell scripts to encrypt files and propagate across the victim network.

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

2. T1547.001 Registry Run Keys / Startup Folder PersistencePrivilege Escalation

   What they do: goznym leverages registry run keys and startup folders to ensure malware execution upon system reboot for persistence.

   What that means: Adversaries may achieve persistence by adding a program to a startup folder or referencing it with a Registry run key.

3. T1685 Disable or Modify Tools Defense Impairment

   What they do: goznym disables antivirus and security tools by terminating processes and modifying system configurations to evade detection.

   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. T1027.013 Encrypted/Encoded File Stealth

   What they do: goznym encodes or encrypts its own malware binaries and configuration data to avoid static detection by security tools.

   What that means: Adversaries may encrypt or encode files to obfuscate strings, bytes, and other specific patterns to impede detection.

5. T1070.004 File Deletion Stealth

   What they do: goznym deletes Volume Shadow Copies and backup directories via built-in Windows commands to prevent recovery.

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

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

   What they do: goznym moves laterally through SMB and Windows administrative shares to access additional victim machines.

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

7. T1486 Data Encrypted for Impact Impact

   What they do: goznym encrypts victim files using a custom ransomware algorithm to hold data hostage for ransom demands.

   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.

8. T1489 Service Stop Impact

   What they do: goznym stops critical Windows services and processes using command scripts to disrupt system functionality before encryption.

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