enum4linux-ng -A [-u "<username>" -p "<passwd>"] <IP>
```

### Enumerate Users, Groups & Logged On Users

```bash
# This info should already being gathered from enum4linux and enum4linux-ng
crackmapexec smb 10.10.10.10 --users [-u <username> -p <password>]
crackmapexec smb 10.10.10.10 --groups [-u <username> -p <password>]
crackmapexec smb 10.10.10.10 --groups --loggedon-users [-u <username> -p <password>]

## Shared Folders Enumeration

### List shared folders

```bash
smbclient --no-pass -L //<IP> # Null user
smbclient -U 'username[%passwd]' -L [--pw-nt-hash] //<IP> #If you omit the pwd, it will be prompted. With --pw-nt-hash, the pwd provided is the NT hash
smbclient \\\\192.168.50.212\\secrets -U Administrator --pw-nt-hash 7a38310ea6f0027ee955abed1762964b


smbmap -H <IP> [-P <PORT>] #Null user
smbmap -u "username" -p "password" -H <IP> [-P <PORT>] #Creds
smbmap -u "username" -p "<NT>:<LM>" -H <IP> [-P <PORT>] #Pass-the-Hash
smbmap -R -u "username" -p "password" -H <IP> [-P <PORT>] #Recursive list

crackmapexec smb <IP> -u '' -p '' --shares #Null user
crackmapexec smb <IP> -u 'username' -p 'password' --shares #Guest user
crackmapexec smb <IP> -u 'username' -H '<HASH>' --shares #Guest user
```

### **Connect/List a shared folder**

```bash
#Connect using smbclient
smbclient --no-pass //<IP>/<Folder>
smbclient -U 'username[%passwd]' -L [--pw-nt-hash] //<IP> #If you omit the pwd, it will be prompted. With --pw-nt-hash, the pwd provided is the NT hash
#Use --no-pass -c 'recurse;ls'  to list recursively with smbclient

#List with smbmap, without folder it list everything
smbmap [-u "username" -p "password"] -R [Folder] -H <IP> [-P <PORT>] # Recursive list
smbmap [-u "username" -p "password"] -r [Folder] -H <IP> [-P <PORT>] # Non-Recursive list
smbmap -u "username" -p "<NT>:<LM>" [-r/-R] [Folder] -H <IP> [-P <PORT>] #Pass-the-Hash
```

```
smbclient -U '%' -N \\\\<IP>\\<SHARE> # null session to connect to a windows share
smbclient -U '<USER>' \\\\<IP>\\<SHARE> # authenticated session to connect to a windows share (you will be prompted for a password)
```

### Mount a shared folder

```
mount -t cifs //x.x.x.x/share /mnt/share
mount -t cifs -o "username=user,password=password" //x.x.x.x/share /mnt/share
