x86_64 Assembly Language and Shellcoding on Linux

This course focuses on teaching the basics of 64-bit assembly language for the x86_64 family of processors on the Linux platform and applying it to Infosec. Once we are through with the basics, we will look at writing shellcode, encoders, decoders, crypters and other advanced low level applications.

The course outline follows the exact same outline of our 32-bit course but all the topics will be taught with x86_64 64-bit assembly.
A non-exhaustive list of topics to be covered include:

  • Computer Architecture Basics
  • x86/x86_64 Family
  • Compilers, Assemblers and Linkers
  • CPU Modes and Memory Addressing
  • Tools of the trade
    • Nasm, Ld, Objdump, Ndisasm etc.
  • x86_64 Assembly Language
    • Registers and Flags

    • Procedures, Prologues and Epilogues
    • Syscall structure and ABI for Linux
    • Calling standard library functions
    • FPU instructions
    • MMX, SSE, SSE2 etc. instruction sets
  • Shellcoding on Linux
    • Execution environment

Backtrack 5: Wireless Penetration Testing     (5 Stars on Amazon.com)

Written in beginner friendly format, Backtrack 5: Wireless Penetration Testing will allow you to easily grasp the concepts and understand the techniques to perform wireless attacks in your lab. Every new attack is described in the form of a lab exercise with rich illustrations of all the steps associated. You will practically implement various attacks as you go along. If you are an IT security professional or a security consultant who wants to get started with wireless testing with Backtrack, or just plain inquisitive about wireless security and hacking, then this book is for you. The book assumes that you have familiarity with Backtrack and basic wireless concepts.

Kali Linux: Wireless Penetration Testing     (5 Stars on Amazon.com)

As wireless networks become ubiquitous in our lives, wireless penetration testing has become a key skill in the repertoire of the professional penetration tester. The Kali Linux security distribution comes with a myriad of tools used for networking attacks and detecting security loopholes. Kali Linux Wireless Penetration Testing Beginner's Guide presents wireless pentesting from the ground up, introducing all elements of penetration testing with each new technology. Learn various wireless testing methodologies by example, from the basics of wireless routing and encryption through to detailed coverage of hacking methods and attacks such as the Hirte and Caffe Latte.

Make your own Hacker Gadget     (Release in 2016)

Make your own Hacker Gadget will guide you step by step through the process of using off-the-shelf commodity Wi-Fi routers and the open source OpenWrt operating system for embedded devices to create custom gadgets. These gadgets can be used for remote monitoring, automating network pentests and intrusion detection and prevention. The focus of this book will be to create a gadget to do Wi-Fi pentests and attack automation.

Vivek explains everything in a methodical, easy to understand and beginner friendly way. No prior experience of working with embedded devices or OpenWrt is assumed. You will be learning how to create a pentest platform for Wi-Fi auditing, though the process taught can be easily adapted for auditing other technologies as well.
