7MS #390: Tales of Internal Network Pentest Pwnage - Part 11

Today's episode is a twofer. That's right, two tales of internal network pentest pwnage. Whoop whoop! We cover:

  • What the SDAD (Single Domain Admin Dance) and DDAD (Double Domain Admin Dance) are (spoiler: imagine your dad trying to dance cool...it's like that, but more awkward)

  • A good way to quickly find domain controllers in your environment: nslookup -type=SRV _ldap._tcp.dc._msdcs.YOURDOMAIN.SUFFIX

  • This handy script runs nmap against subnets, then Eyewitness, then emails the results to you

  • Early in the engagement I'd highly recommend checking for Kerberoastable accounts

  • I really like Multirelay to help me pass hashes, like:

MultiRelay.py -t 1.2.3.4 -u bob.admin Administrator yourmoms.admin

  • Once you get a shell, run dump to dump hashes!

  • Then, use CME to pass that hash around the network!

crackmapexec smb 192.168.0.0/24 -u Administrator -H YOUR-HASH-GOES-HERE --local auth

  • Then, check out this article to use NPS and get a full-featured shell on your targets
