[t3l3machus/Villain#106] add custom callback for every new connection resolve

[BlueBeret]

resolve #106

Add a callback feature

user can easily add python script as callback which will be executed. For example, I use this with discord webhook to get noification for every new backdoor connection.

usage: python3 Villain.py -cb "/tmp/cb.py"

cb.py

import requests
import os
import json
def callback(sess):
    # send discord message
    url = "#redacted"

    data = {
        "content": f"""```{sess}
        ```
        """
    }
    headers = {
        "Content-Type": "application/json"
    }
    response = requests.post(url, data=json.dumps(data), headers=headers)
    if response.status_code == 204:
        return 1
    else:
        return 0
