Recommendations
- Monitor SMB traffic for connections from 34.140.175.127 and implement temporary blocking if operationally feasible
- Disable SMBv1 protocol across the network infrastructure if not already implemented
- Review SMB share permissions and ensure principle of least privilege is enforced
- Enable enhanced logging for SMB authentication attempts and file access events
- Consider implementing network segmentation to limit SMB protocol exposure to untrusted networks
