}
Remediation Steps:
Immediately isolate the infected machine from the network to prevent lateral movement. Use a trusted antivirus tool to perform a full scan and remove the threat. Since Emotet downloads other malware, investigate for signs of further compromise, change all account passwords, and consider re-imaging the system as the safest course of action.
