  2. '''
  3. Description:   ARP poisons a LAN victim and prints all the interesting unencrypted info like usernames, passwords and messages. Asynchronous multithreaded arp spoofing packet parser.
  4. Prerequisites: Linux
  5.               nmap (optional)
  6.               nbtscan (optional)
  7.               aircrack-ng
  8.            Python 2.6+
  9.               nfqueue-bindings 0.4-3
  10.               scapy
  11.               twisted
  12.  
  13. Note:          This script flushes iptables before and after usage.
  14.  
  15. To do:         1. Rogue DHCP server
  16.            Refactor with lots of smaller functions
  17.            Mass wifi jammer
  18.            Cookie saver so you can browse using their cookies (how to use nfqueue with multiple queues?)
  19.            Add karma MITM technique
  20.            Add SSL proxy for self-signed cert, and make the script force a single JS popup saying there's a temporary problem with SSL validation and to just click through
  21.            Integrate with wifite
