Mitigation Recommendations
To protect against this threat, the SOC recommends the following measures:

1. Update Systems: Ensure that all systems are updated with the latest security patches, particularly for Microsoft products.

2. Implement Multi-Factor Authentication (MFA): MFA adds an extra layer of security by requiring additional verification beyond just a password.

3. Network Segmentation: Segment networks to limit lateral movement within the network in case of a breach.

4. Monitor Anomalies: Use advanced threat detection tools to monitor for any unusual activities that may indicate a potential attack.

5. Employee Training: Conduct regular training sessions to educate employees about phishing attempts and other social engineering tactics.

6. Regular Audits: Perform regular security audits and vulnerability assessments to identify and address potential weaknesses in the system.

7. Use Endpoint Protection Solutions: Deploy endpoint protection solutions that can detect and mitigate advanced threats in real-time.

8. Incident Response Plan: Develop and maintain an incident response plan to quickly react to any detected threats.

The SOC will continue to monitor this threat and provide updates as new information becomes available. For more detailed information, please refer to the external references provided above.
