VYPR

MITRE ATT&CK does not currently catalogue VYPR, 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 v20.0. Confidence: medium. Treat it as orientation, not attribution.

1. T1059.001 PowerShell Execution

   What they do: VYPR executes malicious payloads via PowerShell to stage ransomware components across compromised systems.

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

2. T1569.002 Service Execution Execution

   What they do: VYPR executes ransomware processes through Windows service mechanisms to ensure persistence and reliability.

   What that means: Adversaries may abuse the Windows service control manager to execute malicious commands or payloads.

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

   What they do: VYPR adds itself to Windows startup folders and registry run keys to maintain persistence after reboot.

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

4. T1685 Disable or Modify Tools Defense Impairment

   What they do: VYPR disables antivirus and security tools using registry modifications and service interference to prevent 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.

5. T1027.013 Encrypted/Encoded File Stealth

   What they do: VYPR encrypts and encodes victim files with custom ransomware keys to prevent decryption without payment.

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

6. T1070.004 File Deletion Stealth

   What they do: VYPR deletes Volume Shadow Copies and backup artifacts via system commands to eliminate recovery options.

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

7. T1083 File and Directory Discovery Discovery

   What they do: VYPR performs file and directory discovery to identify critical documents and system folders for targeted 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.

8. T1135 Network Share Discovery Discovery

   What they do: VYPR uses network share discovery to locate victim file shares and storage paths for encryption targets.

   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.

9. T1614.001 System Language Discovery Discovery

   What they do: VYPR discovers system language settings to tailor ransom notes and localization strings for victims.

   What that means: Adversaries may attempt to gather information about the system language of a victim in order to infer the geographical location of that host.

10. T1486 Data Encrypted for Impact Impact

    What they do: VYPR encrypts victim files and directories using its ransomware payload to maximize operational disruption.

    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.

11. T1489 Service Stop Impact

    What they do: VYPR stops critical Windows services such as backup and security services to disrupt recovery and monitoring.

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

12. T1490 Inhibit System Recovery Impact

    What they do: VYPR inhibits system recovery by corrupting restore points and disabling backup services to sustain impact.

    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.
