## Tools to Enumerate SMB
smbclient, crackmapexec, and smbmap.
Example
```
User@VM$ cme smb <TARGET IP>
```
To List Shares
```
User@VM$ cme smb <TARGET IP> --shares -u '' -p ''
```
To above example will look for smb shares with the user set as anonymous and with a blank password. To enter a user or password simply input the characters within the ' ' .
To access discovered shares the use of smbclient is particularly helpful.
Example
```
User@VM$ smbclient -N //<TARGET IP>//<SHARE>
```
The above example does not specify a user and will therefore defualt to the system user-name. the "-N" flag equates to no password.
