The python libraries written by people to enable interaction with different services can be used to emulate a client. Such emulated clients can be used for information gathering, monitoring, and even attacking. In this section, we will learn how to use Python libraries to emulate a client. 


What will you learn?


  • Emulate IMAP/Samba client using Python libraries


References:


  1. Twisted library  (https://github.com/twisted/twisted)

  2. Impacket library (https://github.com/SecureAuthCorp/impacket)


Labs Covered:


  • Emulating IMAP Client

    In this lab, you will learn to login into an IMAP server using the credentials of a user and fetch all his emails. The twisted Python library will be used for this.


  • Dictionary Attack: IMAP Server

    In this lab, you will learn to perform a serial dictionary (i.e. trying one password at a time) attack to figure out the correct password for a user using the twisted Python library.


  • Dictionary Attack: IMAP Server (Parallel Attempts)

    In this lab, you will learn to perform a parallel dictionary (i.e. trying multiple passwords at the same time using multiple threads) attack to figure out the correct password for a user using the twisted Python library.


  • Samba Client Emulation II

    In this lab, you will learn to interact with a Samba server using Impackaet Python library. This is a practice lab.
