Lab401 Workshop: RF Hacking with Software-Defined Radio

Introduction

In this 3-day workshop, clients will learn about Software-Defined Radio applied against physical intrusion system (alarms, intercoms, various remotes, etc.). This course provides basics, survival reflexes when testing real-world radio devices and methods to go further. Compared to similar workshops, this class focuses on building a deep of understanding of publicly available tools, and how to build custom tools to analyze and attack targeted systems.

Featuring theoretical and practical elements with emphasis on one-on-one attention, clients will leave with immediately practical techniques for attacking radio devices in real-world environments, such as red-teaming and pentesting.

RF Security Expert

SΓ©bastien Dudek is the founder and a security engineer at PentHertz.

He has been particularly passionate about flaws in radio-communication systems, and published researches on mobile security (baseband fuzzing, interception, mapping, etc.), and on data transmission systems using the power-line (Power-Line Communication, HomePlug AV) like domestic PLC plugs, as well as electric cars and charging stations.

He also focuses on practical attacks with various technologies such as Wi-Fi, RFID and other systems that involve wireless communications.
