7MS #692: Tales of Pentest Pwnage – Part 76
7 Minute Security
Happy Friday! Today’s another hot pile of pentest pwnage. To make it easy on myself I’m going to share the whole narrative that I wrote up for someone else: I was on a pentest where a DA account would sweep the networks every few minutes over SMB and hit my box. But SMB signing was on literally everywhere. The fine folks here recommended I try relaying to something NOT SMB, like MSSQL. This article had good context on that: . I relayed the DA account to a SQL box that BloodHound said had a “session” from another DA. One part I can’t explain is the first relay got me a shell in...

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.

7MS #688: Building a Pentest Training Course Is Fun and Frustrating
7 Minute Security
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
7 Minute Security
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: What ever happened with the annoying apartment neighbor who stomped around like a rhino when you made any noise during COVID? What happened to...

7 Minute Security
This week I’m working on a mixed bag of fun security and marketing things: A pentest I’m stuck on My latest lab CTF obsession: A cool “about 7MinSec” marketing video that was recorded in a pro studio!
info_outlineToday 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.
