The Universal Radio Hacker (URH) is a tool for analyzing unknown wireless protocols. With the rise of the Internet and things (IoT), such protocols are becoming more common.
Many IoT devices operate on frequencies such as 433,92 MHz or 868,3 MHz and use proprietary communication protocols. Reverse engineering protocols can be exciting and reveal serious security leaks e.g. when bypassing smart alarm systems and door locks.
The Universal Radio Hacker is a software for exploring unknown wireless protocols. Features include:
- hardware interfaces for Radio software
- Easy demodulation of signals
- Retention of your data
- Customizable decodings to break even sophisticated encodings such as CC1101
- Assign tags to reveal the logic of the protocol
- Fuzzy component to find security leaks
- Configuration support for data injection back into the system
As the name implies, SDRs need software to function properly. This is where Universal comes in Radio Hacker: Takes samples from SDRs and converts them to binary information (bits). But this is just the beginning: URH is designed to help you throughout the process of attacking IoT wireless devices.
In the following sections, you will learn how to use URH and reverse mechanical protocols in minutes.
