7MS #382: Tales of Internal Network Pentest Pwnage - Part 9

Today's episode is brought to you by ITProTV. It's never too late to start a new career in IT or move up the ladder, and ITProTV has you covered - from CompTIA and Cisco to EC-Council and VMWare. Get over 65 hours of IT training for free by visiting https://itpro.tv/7minute.

Today's episode is about a pentest that was pretty unique for me. I got to ride shotgun and kind of be in the shadows while helping another team pwn a network.

This was an especially interesting one because the client had a lot of great security defenses in place, including:

  • Strong user passwords
  • A SIEM solution that appeared to be doing a great job

We did some looking for pwnage opportunities such as:

  • Systems missing EternalBlue patch
  • Systems missing BlueKeep patch

What got us a foot in the door was the lack of SMB signing. Check this gist to see how you can use RunFinger.py to find hosts without SMB signing, then use Impacket and Responder to listen for - and pass - high-priv hashes.

Side note: I'm working on getting a practical pentesting gist together in the vein of Penetration Testing: A Hands-On Introduction to Hacking and Hacker Playbook.

7MS #681: Pentesting GOAD – Part 3

Today Joe "The Machine" Skeen and I pwn the third and final realm in the world of GOAD (Game of Active Directory): essos.local! The way we go about it is to do a WinRM connection to our previously-pwned Kingslanding domain, coerce authentication out of MEEREEN (the DC for essos.local) and then capture/abuse the TGT with Rubeus! Enjoy.
