• TryHackme AttacktiveDirectory

Use cases

For each of the cases described, the linWinPwn script performs different checks as shown below.

Case 1: Unauthenticated

• Module ad_enum
  • rid bruteforce
  • user enumeration
  • ldapdomaindump anonymous enumeration
  • Check if ldap-signing is enforced, check for LDAP Relay
• Module kerberos
  • kerbrute user spray
  • ASREPRoast using collected list of users (and cracking hashes using john-the-ripper and the rockyou wordlist)
• Module scan_shares
  • SMB shares anonymous enumeration on identified servers
• Module vuln_checks
  • Enumeration for WebDav and Spooler services on identified servers
  • Check for zerologon, petitpotam, nopac weaknesses

./linWinPwn.sh -M user -t <Domain_Controller_IP_or_Target_Domain>

Case 2: Standard Account (using password, NTLM hash or Kerberos ticket)

• DNS extraction using adidnsdump
• Module ad_enum
  • BloodHound data collection
  • ldapdomaindump enumeration
  • Delegation information extraction
  • GPP Passwords extraction
  • Extract ADCS information using certipy
  • Check if ldap-signing is enforced, check for LDAP Relay
  • Extraction of MachineAccountQuota of user, Password Policy and users’ descriptions containing “pass”
  • LAPS and gMSA dump
• Module kerberos
  • kerbrute user=pass enumeration
  • ASREPRoasting (and cracking hashes using john-the-ripper and the rockyou wordlist)
  • Kerberoasting (and cracking hashes using john-the-ripper and the rockyou wordlist)
• Module scan_shares
  • SMB shares enumeration on all domain servers
• Module vuln_checks
  • Enumeration for WebDav and Spooler services on all domain servers
  • Check for zerologon, petitpotam, nopac weaknesses
• Module mssql_enum
  • Check mssql privilege escalation paths

./linWinPwn.sh -M user -d <AD_domain> -u <AD_user> -p <AD_password_or_hash[LM:NT]_or_kerbticket[./krb5cc_ticket]> -t <Domain_Controller_IP_or_Target_Domain>

Case 3: Administrator Account (using password, NTLM hash or Kerberos ticket)

• All of the “Standard User” checks
• Module pwd_dump
  • secretsdump on all domain servers or on provided list of servers with -S
  • lsassy on on all domain servers or on provided list of servers with -S

./linWinPwn.sh -M all -d <AD_domain> -u <AD_user> -p <AD_password_or_hash[LM:NT]_or_kerbticket[./krb5cc_ticket]> -t <Domain_Controller_IP_or_Target_Domain> -S <domain_servers_list>
