Usage Tips

. DO NOT USE QUOTES in path names, for example use file name instead of "file name" when changing directories with cd
. If you want to upload a file it should be placed in the same directory as the file.
. spawn module will spawn a separate shell using powershell for windows, catch it with netcat.
. While using the CNC shell your prompt will be like this: [ CNC ] >>> and it can run local system commands.
. To get a list of all available commands in CNC or backdoor prompt simply type help.
. ANY COMMAND not included in the help banners will be executed as system shell commands so be carefull with that.
