Recommendations
- Block IP address 34.53.160.242 at network perimeter and update threat intelligence feeds
- Disable SMB1 protocol across all systems and ensure SMB2/3 with signing enabled
- Implement enhanced logging and monitoring for RSYNC services, particularly authentication attempts
- Review and restrict RSYNC service exposure to essential systems only with strong authentication
- Conduct immediate security assessment of systems that may have been targeted during the 25-day campaign window
