Linux Rootkits for Red-Blue Teams

Linux dominates the Server, Embedded and now the Internet of Things (IoT) device market. In recent times, embedded systems and IoT devices in particular have been the weapons of choice in online attacks: botnets like Mirai and Reaper to name a few. Soon the simple attack vectors that these botnets and malware use get patched, it is obvouis that the attacker will move and hide his tools in Kernel mode. This course will teach Red-Blue teams how kernel mode attack kits work and what to go about protecting their systems against it. We will use examples on x86_64, ARM and MIPS based architectures.

This entire course will be run on the latest Linux Kernel 4.15.x. This course is completely hands-on and everything will be taught with practical examples in the form of Kernel Modules written in C. You can however follow this course with a basic knowledge of Linux as we discuss everything from the very basics.

A non-exhaustive list of topics include:

  • Linux Boot Process
  • Browsing the Kernel code
  • Linux Architecture and Process Internals
  • Loadable Kernel Module (LKM) Programming Basics
  • Understading internal kernel structures and the syscall mechanism
  • Interrupt and Process context, Timers and Watchdogs
  • Manipulating internal process structures
  • Hijacking the system call table
  • Subverting kernel memory protections
  • Monitoring the system with Kprobes
  • Kernel syncronization methods and common LKM pitfalls
  • User space - Kernel space data transfers
  • Monitoring a user space process from the kernel
  • Accessing user space process memory
  • Modifying the core kernel code to create custom hooks
  • Understanding the kernel network stack
  • Netfilters and Custom Hooks
  • Network packet filtering and mangling with custom LKMs
  • Analyzing Kernel mode Rootkits
  • Defending against Kernel Mode attacks
  • Chain of trust implementations
  • and other topics

 Videos will start getting posted shortly.

Books Authored by Vivek


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.
