URH runs on Linux, OSX and Windows and is easy to install.

In the upcoming sections, you will learn how to use URH and reverse engineer wireless protocols in minutes. But this is only the beginning: URH is designed to help you throughout the entire process of attacking the wireless communication of IoT devices. This is where the Universal Radio Hacker comes into play: It takes the samples from the SDR and transforms them into binary information (bits).

Like the name suggests, SDRs need software to be properly operated. (b) SDRplay RSP2pro can receive on frequencies from 1 kHz to 2 GHz.įigure 1: Two examples for Software Defined Radios. (a) HackRF One can send and receive on frequencies from 1 MHz to 6 GHz. Such devices allow sending and receiving on nearly arbitrary frequencies. So how can we join this game? Software Defined Radios (SDR) are the answer for this. when bypassing smart alarm systems and door locks. Reverse-engineering such protocols can be fascinating (»What does my fridge talk about?«) and reveal serious security leaks, e.g. Many IoT devices operate on frequencies like 433.92 MHz or 868.3 MHz and use proprietary protocols for communication.

With the rise of Internet of Things (IoT) such protocols often appear in the wild. The Universal Radio Hacker (URH) is a tool for analyzing unknown wireless protocols. This article is from Open Source Tools edition, that you can download for free if you have an account on our website.
