The ARM IoT Exploit Laboratory
Saumil Shah

Introduction

"There's an Intel on every desktop, but an ARM in every pocket."

The Internet of Things (IoT) universe comprises largely of ARM based systems. The ARM IoT Exploit Laboratory brings you an intense 4-day course featuring a practical hands-on approach to exploit development on ARM based systems. This class is perfectly suited for students who are keen to dive into the world of modern ARM exploit development.

Our intermediate level class begins with an introduction to ARM architecture and ARM assembly language and moves quickly onto debugging techniques for ARM systems, exploiting buffer overflows on ARM devices running Linux, writing ARM shellcode from the ground up, and bypassing exploit mitigation techniques with ARM Return Oriented Programming (ROP). Our lab environment features both hardware and virtual machine targets.

The class concludes with an end-to-end "Firmware-To-Shell" hack, testing out ARM exploitation skills against commercial ARM based SoHo routers and IP surveillance cameras. Students will extract the manufacturer's firmware, learn how to analyse and debug it in a virtual environment, build an exploit which involves tight ROP chaining and ASLR bypass, and finally succeed in getting a shell on the actual hardware.
