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- Prioritize upgrading these systems to a supported and patched version of Windows 10 or later, as this version is outdated and unsupported.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