secretsdump.py dcsync attack | extract password hashes

solving sauna hack the box challenge. scenario is, we have got evil-winrm shell on the remote AD box. then we have uploaded winPEAS.exe privilege escalation .exe on the remote box. after executing that on the remote box we have found that there is a account on AD named svc_loanmgr along with the password. then after doing some bloodhound we have identify that this account has the privilege to dcsync.

from parrot machine: because secretsdump.py tool will not be installed on the remote AD.

secretsdump.py egotistical-bank.local/svc_loanmgr@10.10.10.175 (press enter, it will ask svc_loanmgr account password)

mimikatz:

lsadump::dcsync /domain:egotistical-bank.local /user:svc_loanmgr
