What it detects

This rule detects creation of a symbolic link into a GLOBALROOT HarddiskVolumeShadowCopy device path, a technique Huntress observed for reading locked files such as SAM, SYSTEM, and NTDS.DIT from a volume shadow copy. Attackers use the shadow copy to bypass file locks and exfiltrate credential stores. Linking to a shadow copy device object is anomalous and indicates credential-store access.
