RF Hacking with Software-Defined Radio full-course

RF Hacking with Software-Defined Radio full-course

In this 4-day training, students will learn about software-defined radio applied to security and will get survival reflexes and methods to test real-world radio devices (intercoms, cars, industrial modules, mobile phones, various remote controls, as well as other IoT systems).

Compared to other courses that teach how to use public tools, this class is more about understanding how these tools work and also how to build proper tools to analyze and attack targeted systems

All techniques here will demonstrate real uses-cases encountered in pentests and Red Teams, but also techniques that aim to be applied to future systems, by teaching important steps when dealing with unknown targets.

What the class will teach

With this class students will learn how to find interesting radio-communications and ways to attack targeted systems:

  • Learn how radio works and about actual technologies using this interface
  • Find and analyze a signal
  • Modulate and demodulate a signal
  • Encode and decode data meant to be transported over-the-air
  • Capture, generate, replay and analyze a signal
  • Interface with a signal using SDR devices and software
  • Get primary reflexes to attack embedded and IoT systems
  • Create your own tools with the GNU Radio framework and its alternatives
  • Learn how to use SDR and classical attacks on mobile 2G/3G/4G, RFID/NFC, LoRa, wireless mousses/keyboards/presenters, sub-GHz remotes/alarms, and other similar or custom technologies

Day 1 - RF preliminaries
