title: Network Share Discovery (T1135)
id: df00tech-t1135
status: experimental
description: "Adversaries may look for folders and drives shared on remote systems as a means of identifying sources of information to gather as a precursor for Collection and to identify potential systems of interest for Lateral Movement. Networks often contain shared network drives and folders that enable users to access file directories on various systems across a network. File sharing over a Windows network occurs over the SMB protocol. Net can be used to query a remote system for available shared drives using the net view \\\\remotesystem command. It can also be used to query shared drives on the local system using net share. For macOS, the sharing -l command lists all shared points used for SMB services. Adversaries including Conti, BlackByte, Medusa, Latrodectus, QakBot, and Cuba have all leveraged network share discovery as a precursor to lateral movement, ransomware staging, and data collection operations, frequently calling NetShareEnum() directly or through net.exe wrappers."
