Remediation Steps:
Immediately isolate the affected host from the network. Conduct a full system scan with updated antivirus definitions and manually remove any identified malicious files (e.g., 'quotation.exe', 'boosting.exe', 'Ds.exe') and persistence mechanisms. Block all associated C2 domains and IP addresses (e.g., 45.78.21.150, kuzov-remont.com) at the network perimeter.
