Windows systems within the Windows NT family contain hidden network shares that are only accessible to system administrators. These shares allow administrators to remotely access all disk volumes on a network-connected system and further allow for files to be copied, written, and executed, along with other administrative actions. Example network shares include: C$, ADMIN$ and IPC$. If an adversary is able to obtain legitimate Windows credentials, the hidden shares can be accessed remotely, via server message block (SMB) or the Net utility, to transfer files and execute code. It is also possible for adversaries to utilize NTLM hashes to access administrator shares on systems with certain configuration and patch levels.
