Finding Buried Treasure in Server Message Block (SMB)

This guide outlines how to identify and assess sensitive content exposure via SMB shares at scale in Windows AD environments using tools like PowerView/SharpView and targeted regex searches, focusing on high-risk shares (Admin$, deployment, root drives, web roots, and backups) that can expose credentials and enable lateral movement. It then provides mitigation strategies—share minimization, correcting NTFS/share permissions, network segmentation, and UEBA for anomalous access—along with continuous auditing using Snaffler to reduce risk and prevent attackers from leveraging misconfigurations.
