    7MS #746: Claude is Really Good at PowerPoint

    Hey friends, today I'm sharing something that might be obvious, but really helped save my bacon this week: Claude is very good at PowerPoint.  I was working on a presentation with my friends at Netwrix (go catch the replay!), and was suffering some creative designer's/writer's block.  Claude got my juices flowing by taking raw recordings of pentest attacks and then Frankenstein-ing them to look like they came from a completely different (and cool!) Halloween-themed domain called HALLOWEEN.LOCAL.  I think today's episode is a great example of how you can use AI to bring a vision to life while staying in charge of the project's overall vision and not letting AI do all the thinking and creative work for you.

    7MS #745: Securing Your Family During and After a Disaster – Part 10

    This episode is a downer, but asks some important topics related to losing a loved one: Do you know what their wishes are for their funeral, their money, cremation vs. burial vs. other? Do you know all the places they do business so you can adjust/takeover/cancel services as necessary? Do you know all the places the have checking/saving/investment accounts? Can you access all the important accounts this person used to manage?

    7MS #744: Using n8n to Automate the Security Dog Food

    Hey friends! Today I'm mashing two of our mini-series — eating the security dog food and my new obsession with n8n — into one big automation sandwich. I'll walk you through how Claude and a bunch of JSON files helped me build a self-updating asset inventory in Notion, firewall rule reviews, patch-ticket automation, and a push-button external pentesting and OSINT sweep. Basically, imagine I've cornered you at a party and won't stop talking about n8n.

    7MS #743: Eating the Security Dog Food - Part 9

    Hey friends, it has been a long time since we talked about eating our own security dog food.  However, I couldn't be more excited about some big ways we've moved the 7MinSec security program forward, including the release of our shiny new trust center.  Enjoy!

    7MS #742: Baby's First n8n

    Hey friends! I've got some personal and work travel this week, so I'm skipping the tangents (mostly) and jumping straight into something I'm nerdily excited about: Baby's First n8n. If you're not familiar, n8n is a platform for chaining together and automating just about anything your heart desires – and naturally, my heart desires automating away the boring parts of pentesting. In this episode I cover how I finally got hip to n8n (late to the party, as always), the Black Hills webcast that nudged me into it, how I fed Claude my Frankenstein "Swiss Army" pentest script and asked it to turn push-lots-of-buttons into push-one-button, the clever workaround for firing nmap, EyeWitness, and other tools like it (plus the safety gate I built so my automation can't go rogue and get me in trouble), a full OSINT recon fork powered by Project Discovery Neo that lands report-ready in SysReptor, and the many minutes of my life I get back from each OSINT run – and why that's the whole point. By the way, n8n is not a sponsor or partner – just something I like in case you like it too. Got cool n8n workflows of your own? I'd love to hear 'em!

    7MS #741: Tales of Pentest Pwnage - Part 91

    Hey friends! Today's tale of pentest pwnage is brought to you by four hours of sleep, a large mint hot cocoa, and unhealthy levels of giggity. There's a very good reason for all three, but you'll have to hang out to the end of the episode to hear it. First, let's talk about an escalation path I've never walked before: A really tight network is a beautiful and terrible thing — this client went from a C-minus-ish environment in past years to one where I could find basically nothing. No local admin creds laying around, no poisonable protocols, no juicy file shares. Straight into "well, try harder" mode I went. Two new-to-me tools join the arsenal — one that gives you a second opinion on a big pile of pilfered files (Titus), and a one-shot PowerShell command (GPOZaurr) that hands you a report card for everything that's wrong with your GPOs (plus how to fix it). The finding I almost walked right past — an ADCS issue where only a tiny handful of objects could enroll. I said "all right, I'll move on." Then I came back to it, and saw I had missed the (kind of) obvious attack path. A certificate I couldn't authenticate with — and the 0xdf write-up that rescued me from my own gap in knowledge. Machine account quota was set to zero — so of course I tried to add a computer object anyway. Spoiler: it worked like a dirty shirt. The scheduled task trick rides again — my favorite "this is not going to get fixed" Windows behavior. I had a client push back on this one hard: "You had to know the password of the DA you abused, right? You stole the TGT, right?" Nope and nope. How to actually defend against all of this — some ADCS tightening, a checkbox on your high-privilege accounts that a lot of folks don't have ticked, and my new mantra: RDP with purpose. And then it's personal time — my oldest son Cam passed his national paramedic exam, and I am busting my buttons. Stick around for the whole story, including the 4 a.m. potty break that changed everything, the two health care professionals I'd like to hand a party invitation to in person (and why my wife says "I don't know about that, dude").

    7MS #740: Tales of Pentest Pwnage - Part 90

    Hey friends! We've been on a bit of a Tales of Pentest Pwnage bender lately, so let's keep it rolling with Part 90. (And Mom, relax — this is not one pentest story chopped into 90 parts.) Today is less of an A-to-Z story and more a pile of tips and tricks pulled from a recent string of SCCM-flavored internals — plus a tangent about a video game and a little robot Claude and I built to get my life back. Multi-tier SCCM is having a moment — I've never administered SCCM a day in my life, but 2026 keeps dropping me into these split-role environments. Here's where I go to figure out my attack surface when all I've got is a low-priv cred. SMB signing on? Cool, I'll go around it — relaying from one SCCM box to the one with SQL on it, and the easy-button tool that vacuums the good stuff out of the database once you're there. (NAA creds, clear-text local admin passwords, install scripts with creds baked in…yes please.) Then relay the other direction — when the loot came back stale, a nudge from a Slack channel had me pointing the relay backwards, and I giggled like a little schoolboy at what popped out. Adding yourself to the local admin group: still weirdly undetected — an old episode of ours reminded me of an Impacket tool I don't see written up on many pentest blogs, and it slipped right by. My favorite cheat code hit a snag — the evil-scheduled-task-under-a-logged-in-DA trick kept coughing up permission errors, so I had to get creative. Plus the defensive recs I'm still trying to sharpen up — if you've got a better way to close this loophole, I'm all ears! Tangent: Halloween (the video game) and the lobby watcher — a million players and I'm still staring into the lobby abyss for 10 minutes at a time. So Claude and I built something that watches the screen and texts me when it's time to sprint back to the keyboard. It's not cheating. It's not! (The Texas Chainsaw crowd disagreed, loudly.)

    7MS #739: Tales of Pentest Pwnage – Part 89

    Hey friends! Today is a tale of pentest pwnage episode, and this one features a path to escalation I have never seen before – one I could only find few references on the entire Internet. It happened completely by accident, but during the report readout I'm absolutely going to say it was intentional and that I totally meant to do that. Here's what we cover: A client that's actually doing the things – year two or three of testing this environment, and they had buttoned up so much that I had to dig deep. Great for them, freaking frustrating for me. Why my Kerberoasting success rate has fallen off a cliff – Microsoft pushed an encryption change earlier this year, and cracking those hashes is a whole different ballgame now. Selective poisoning vs. poison-all-the-things – a nod to Pretender, which I covered in a TuesdayTOOLSday video over at 7MinSec.club. It doesn't get nearly enough love in blogs and videos. The relay that fired… and did something completely different than I expected – I saw the ntlmrelayx log scroll by, thought "yes, I've got DA," and then had a "wait, wait, whoa, what?" moment. I was honestly a little panicked. An ancient Exchange vulnerability comes back to bite – CVE-2021-34470 (vulnerable Exchange schema) turned out to be the fallback that got me a foothold I had no business having. My favorite evil privesc trick, revisited – queuing up a scheduled task that runs under an interactively logged-in DA's context without ever knowing their password. The MDR alerts that come out of this are equal parts hilarious and terrifying. A bonus thing to always look for – scheduled tasks running under saved DA creds that point at a script you can edit. Add one little line to fire an evil command of your choice, and you're in like a dirty shirt. Check us out at 7MinSec.com for pentesting, training, controls assessments and security miscellany, 7MinSec.club for our Substack and weekly TuesdayTOOLSday videos, and 7MinSec.wiki for tips, cheat sheets and scripts (including pages on the scheduled task shenanigans above).
