Sekhmet

MITRE ATT&CK does not currently catalogue Sekhmet, 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: sekhmet executes malicious commands via PowerShell scripts to stage ransomware payloads and system modifications.

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

2. T1059.003 Windows Command Shell Execution

   What they do: sekhmet uses Windows Command Shell (cmd.exe) to run batch files for file encryption and service disruption.

   What that means: Adversaries may abuse the Windows command shell for execution.

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

   What they do: sekhmet adds malicious registry run keys to persist execution after system reboots.

   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: sekhmet disables antivirus tools and modifies Windows Defender settings to evade detection during execution.

   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: sekhmet deletes Volume Shadow Copies and backup directories using vssadmin.exe to prevent data restoration.

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

6. T1110 Brute Force Credential Access

   What they do: sekhmet brute-forces local accounts and credentials using password lists to gain initial system access.

   What that means: Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.

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

   What they do: sekhmet exploits SMB/Windows Admin Shares to move laterally across networked victim machines.

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

8. T1486 Data Encrypted for Impact Impact

   What they do: sekhmet 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.

9. T1489 Service Stop Impact

   What they do: sekhmet stops critical Windows services via kill.bat or equivalent commands to disrupt system recovery and user access.

   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: sekhmet triggers system shutdown commands and disables recovery mechanisms to maximize operational 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.
