Guidance for enterprise administrators

Apply these mitigations to reduce the impact of this threat. Check the recommendations card for the deployment status of monitored mitigations:

• Turn on cloud-delivered protection and automatic sample submission on Microsoft Defender Antivirus. These capabilities use artificial intelligence and machine learning to quickly identify and stop new and unknown threats.
• Turn on attack surface reduction rules, including rules that block malware activity and other activities associated with human adversaries. To assess the impact of these rules, deploy them in audit mode.
• Turn on tamper protection features to prevent attackers from stopping security services.
• Ensure internet-facing assets have the latest security updates. Audit these assets regularly for suspicious activity.
• Use the Microsoft Defender Firewall and your network firewall to prevent RPC and SMB communication among endpoints whenever possible. This limits lateral movement as well as other attack activities.
