AI-suggested

  1. Immediately identify and inventory all systems running Windows 10 Version 1507 within the organization.
  2. Prioritize upgrading these systems to a supported and patched version of Windows 10 or later, as this version is outdated and unsupported.
  3. Until upgrades are complete, restrict user permissions to prevent unauthorized mounting or opening of VHDX files.
  4. Implement strict access controls and monitoring on directories and shares where VHDX files are stored to detect and prevent unauthorized modifications or usage.
  5. Educate users about the risks of opening untrusted VHDX files and implement policies to limit user interaction with unknown virtual disk files.
  6. Monitor local system logs and security events for unusual activity related to VHDX handling or privilege escalation attempts.
  7. Apply any interim security advisories or workarounds released by Microsoft as they become available.
  8. Employ endpoint detection and response (EDR) tools capable of detecting suspicious local privilege escalation behaviors.
  9. Review and harden virtualization and backup processes that utilize VHDX files to minimize exposure.
  10. Maintain up-to-date backups and incident response plans to quickly recover from potential exploitation.
