  • 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)

  • Module kerberos
    • kerbrute user=pass enumeration

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

  • All of the “Standard User” checks
