7MS #261: Blind Network Security Assessments

7MS #261: Blind Network Security Assessments

This week I had the fun opportunity to do a "blind" network security assessment - where basically we had to step into a network we'd never seen before and make some security posture recommendations. I've found that the following software/hardware is quite helpful for this type of assessment:

  • The PwnPulse helps a ton in scanning wired and wireless networks...and even Bluetooth! I've covered the Pulse in past episodes - check out part 1 and part 2.

  • Network Detective will do a ton of helpful Active Directory enumeration and point out potential red flags, such as:

    • Accounts that haven't been logged into for a long time
    • Accounts with passwords that haven't been refreshed in a long time
    • Privileged groups that need review (Domain Admins, Enterprise Admins, etc.)
  • AD policy issues (*warning: by default Network Detective only pulls back a few policies by default. Check out scripts such as my Environment Check to grab a dump of all GPOs.

  • Thycotic Privileged Account Discovery is a free tool that can crawl AD workstations and enumerate the local administrator accounts on each machine. It makes a good case for implementing LAPS.

7MS #644: Tales of Pentest Pwnage – Part 64

Hey!  I’m speaking in Wanatchee, Washington next week at the NCESD conference about 7 ways to panic a pentester!  Today’s tale of pentest pwnage is a great reminder to enumerate, enumerate, enumerate!  It also emphases that cracking NETLM/NETNTLMv1 isn’t super easy to remember the steps for (at least for me) but this crack.sh article makes it a bit easier!

7MS #640: Tales of Pentest Pwnage – Part 63

This was my favorite pentest tale of pwnage to date!  There’s a lot to cover in this episode so I’m going to try and bullet out the TLDR version here: Sprinkled farmer files around the environment Found high-priv boxes with WebClient enabled Added “ghost” machine to the Active Directory (we’ll call it GHOSTY) RBCD attack to be able to impersonate a domain admin using the CIFS/SMB service against the victim system where some higher-priv users were sitting Use net.py to add myself to local admin on the victim host Find a vulnerable service to hijack and have run an evil, TGT-gathering Rubeus.exe – found that Credential Guard was cramping my style! Pulled the TGT from a host not protected with Credential Guard Figured out the stolen user’s account has some “write” privileges to a domain controller Use rbcd.py to delegate from GHOSTY and to the domain controller Request a TGT for GHOSTY Use getST.py to impersonate CIFS using a domain admin account on the domain controller (important thing here was to specify the DC by its FQDN, not just hostname) Final move: use the domain admin ccache file to leverage net.py and add myself to the Active Directory Administrators group

7MS #638: Tales of Pentest Pwnage – Part 61

Today we’re talking pentesting – specifically some mini gems that can help you escalate local/domain/SQL privileges: Check the C: drive! If you get local admin and the system itself looks boring, check root of C – might have some interesting scripts or folders with tools that have creds in them. Also look at Look at Get-ScheduledTasks Find ids and passwords easily in Snaffler output with this Snaffler cleaner script There’s a ton of gold to (potentially) be found in SQL servers – check out my notes on using PowerUpSQL to find misconfigs and agent jobs you might able to abuse!
