Remediation Steps:
Immediately isolate the affected system from the network. Use Windows Defender to run a full scan and remove the threat. After removal, manually verify that all Windows Defender settings (e.g., Real-time protection, Tamper Protection) are enabled and restored to default. Investigate for persistence mechanisms and other signs of compromise, as this tool is often a precursor to a larger attack.
