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

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 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
