Vect

MITRE ATT&CK does not currently catalogue Vect, 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. T1047 Windows Management Instrumentation Execution

   What they do: vect uses Windows Management Instrumentation to execute commands and maintain persistence across systems.

   What that means: Adversaries may abuse Windows Management Instrumentation (WMI) to execute malicious commands and payloads.

2. T1059.001 PowerShell Execution

   What they do: vect uses PowerShell to execute malicious payloads and stage ransomware binaries across targeted systems.

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

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

   What they do: vect modifies Registry Run Keys to ensure ransomware execution upon user logon or system startup.

   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: vect disables antivirus and monitoring tools using registry modifications to evade detection during deployment.

   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. T1070.004 File Deletion Stealth

   What they do: vect deletes Volume Shadow Copies and backup files via system commands to prevent recovery.

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

6. T1003.001 LSASS Memory Credential Access

   What they do: vect accesses LSASS memory to steal credentials for lateral movement and privilege escalation.

   What that means: Adversaries may attempt to access credential material stored in the process memory of the Local Security Authority Subsystem Service (LSASS).

7. T1135 Network Share Discovery Discovery

   What they do: vect probes network shares to identify victim directories and expand encryption targets efficiently.

   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.

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

   What they do: vect leverages SMB/Windows Admin Shares for lateral movement between compromised hosts in the same network.

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

9. T1486 Data Encrypted for Impact Impact

   What they do: vect encrypts critical files using its ransomware payload, applying impact to Finance, Healthcare, and Manufacturing victims.

   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.

10. T1490 Inhibit System Recovery Impact

    What they do: vect calls system recovery inhibitors to block backup restoration and maximize operational disruption.

    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.
