This course is a deep dive into Embedded/IoT firmware where we will start from the very basics - understand the multistage boot process, the kernel and root filesystem, how to build them with a custom toolchain and how they can be compromized with user and kernel mode backdoors/rootkits. We will be using the latest 4.15.x kernel for this course on an ARM architecture board.
A non-exhaustive list of topics to be covered include:
- Embedded/IoT device architecture basics
- Understanding the Boot Process
- Multi-stage Bootloaders
- Creating a custom toolchain with crosstool-NG
- U-boot build and deep dive
- Booting a device manually with u-boot
- Kernel and Device Tree basics
- Custom Kernel and DTB builds
- Building the runtime C library (uClibc)
- Building the root filesystem and BusyBox
- Debugging the system over UART
- Understanding Kernel mode rootkits
- Embedded/IoT system constraints
- Kernel mode rootkits on IoT/Embedded devices
- Syscall monitoring and hijacking
- Process manipulation
- Network stacking hooking with Netfilter
- Kernel mode Network backdoor with C&C
- and many others
We highly recommend watching the Course Introduction video to learn more.

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.
