7MS #405: Tales of Internal Pentest Pwnage - Part 16

This podcast is sponsored by Arctic Wolf, whose Concierge Security teams Monitor, Detect and Respond to Cyber threats 24/7 for thousands of customers around the world. Arctic Wolf. Redefining cybersecurity. Visit Arcticwolf.com/7MS to learn more.

Today's episode of pentest pwnage is the (hopefully) exciting conclusion to this episode. Last we left this pentest, we ran into some excellent blue team defenses, including:

  • MFA on internal servers (which we bypassed)
  • Strong passwords
  • Limited vulnerable protocols (LLMNR/Netbios/etc) available to abuse for cred-capturing
  • Servers that were heavily firewalled off from talking SMB to just any ol' subnet nor the Interwebs (here's a great video on how to fine-tune your software firewall chops)

In today's episode we talk about:

  • How maybe it's not a good idea to make computer go completely "shields down" during pentests

  • Being careful not to fat-finger anything when you spawn cmd.exe with creds, like

runas /netonly /user:samplecompany\billybob "C:\windows\system32\cmd.exe"
  • Being careful not to fat-finger anything when using CrackMapExec

  • How fundamental and really effective blue team controls (such as the ones mentioned above) can really make pentesting a headache!

  • How you should be careful when spawning shells with MultiRelay (part of Responder is it creates new services on your victim machine

7MS #688: Building a Pentest Training Course Is Fun and Frustrating

7MS #688: Building a Pentest Training Course Is Fun and Frustrating

Today I talk about a subject I love while also driving me crazy at the same time: building a pentest training course! Specifically, I dissect a fun/frustrating GPO attack that I need to build very carefully so that every student can pwn it while also not breaking the domain for everybody else. I also talk about how three different flavors of AI failed me in solving a simple task.

7MS #687: A Peek into the 7MS Mail Bag – Part 5

7MS #687: A Peek into the 7MS Mail Bag – Part 5

Hi friends, we're doing something today we haven't done in a hot minute: take a dip into the 7MinSec mail bag! Today we cover these questions: If I'm starting a solo business venture as a security consultancy, is it a good idea to join forces with other solo security business owners and form a consortium of sorts? Have you ever had anything go catastrophically wrong during a pentest? Yes, and this is an important link in the story: https://github.com/fortra/impacket/issues/1436 What ever happened with the annoying apartment neighbor who stomped around like a rhino when you made any noise during COVID? What happened to the "difficult family situation" you vaguely talked about a few months ago that involved police and lawyers – did that ever get resolved?

7MS #686: Our New Pentest Training Course is Almost Ready

Oh man, I'm so excited I can hardly sleep. Our new three-day (4 hours per day) training is getting closer to general release. I talk about the good/bad/ugly of putting together an attack-sensitive lab that students can abuse (but hopefully not break!), and the technical/curriculum-writing challenges that go along with it.

7MS #685: The Time My Neighbor Almost Got Scammed Out of $13K

7MS #685: The Time My Neighbor Almost Got Scammed Out of $13K

Today's kind of a "story time with your friend Brian" episode: a tale of how my neighbor almost got scammed out of $13k. The story has a lot of red flags we can all keep in mind to keep ourselves (as well as kids/friends/parents/etc.) safer from these types of shenanigans.

7MS #681: Pentesting GOAD – Part 3

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.
