rpcclient - A tool for interacting with smb shares
This is a tool to perform MS-RPC functions.
The Remote Procedure Call (RPC) is a central tool to realize operational and work-sharing structures in networks and client-server architectures.
Remote Procedure Call (RPC) is a powerful technique for constructing distributed, client-server based applications. It is based on extending the conventional local procedure calling so that the called procedure need not exist in the same address space as the calling procedure. The two processes may be on the same system, or they may be on different systems with a network connecting them.
Basic usage
# Connect to a remote shared folder (same as smbclient in this regard)
rpcclient -U "" 10.129.14.128
# Server information
srvinfo
# Enumerate all domains that are deployed in the network
enumdomains
# Provides domain, server, and user information of deployed domains.
querydominfo
# Enumerates all available shares.
netshareenumall
# Provides information about a specific share.
netsharegetinfo <share>
# Enumerates all domain users.
enumdomusers
# Provides information about a specific user.
queryuser <RID>
# An example:
# rpcclient $> queryuser 0x3e8
# Provides information about a specific group.
querygroup <ID>
Brute forcing user enumeration with rpcclient
for i in $(seq 500 1100);do rpcclient -N -U "" $ip -c "queryuser 0x$(printf '%x\n' $i)" | grep "User Name\|user_rid\|group_rid" && echo "";done
