Brian Johnson -

Today we continue part 2 of a series we started a few weeks ago all about building a vulnerable pentesting lab. Check out the video above, and here are the main snippets of code and tips to get you going:

  • Use Youzer to import a bunch of bogus users into your Active Directory:
sudo python ./youzer.py --generate --generate_length 20 --ou "ou=Contractors,dc=brifly,dc=us" --domain brifly.us --users 1000 --output lusers.csv
  • Make a Kerberoastable user:
New-AdUser -Name "Kerba Roastable" -GivenName "Kerba" -Surname "Roastable" -SamAccountName Kerba -Description "ROASTED!" -Path "OU=Contractors,DC=brifly,DC=us" -AccountPassword (ConvertTo-SecureString "Password1" -AsPlainText -force) -passThru -PasswordNeverExpires $true
enable-adaccount Kerba
setspn -a IIS_SITE/brifly-dc01.brily.us:77777 briflyus\kerba
