IoT Firmware Exploitation

CPE/ECE Credits: 40

Course Description

This course is designed for hackers, tinkerers, and hobbyists with limited experience and an interest in embedded systems analysis and firmware evaluation techniques. It starts with a basic introduction to electronics, using a series of hands-on lab exercises to give the student a comfortable foundation using various embedded analysis tools and techniques. Students will learn how to identify and extract critical data in the firmware, and perform basic vulnerability analysis on embedded code.

The course continues with advanced emulation and exploitation techniques against MIPS Linux systems, including stack overflows, return to libc and return oriented programming. Students will develop buffer overflow exploits against live MIPS Linux devices using only a firmware update image - no hardware required!

The course culminates with students identifying and exploiting vulnerabilities in a real-world embedded device. At the end of the course, students will have the knowledge and experience to perform hardware and firmware analysis of commercial off-the-shelf embedded systems.

Learning Prerequisites

Students must be proficient in the following areas before starting the class:

• Running Linux commands and awareness of the Linux operating environment
• Experience with scripting languages such as bash, Python, and Perl

Students should at least have introductory knowledge in the following topics:

• Knowledge of common networking protocols (TCP/IP, HTTP)
• Familiarity with IDAPro and GDB debugging
• Experience with vulnerability analysis and exploitation
• Experience using binwalk would be helpful, but not necessary
• Desire to learn by extrapolating instruction and not with a recipe
