The Universal Radio Hacker (URH) is a complete suite for wireless protocol investigation with native support for many common Software Defined Radios.
URH allows easy demodulation of signals combined with an automatic detection of modulation parameters making it a breeze to identify the bits and bytes that fly over the air. As data often gets encoded before transmission, URH offers customizable decodings to crack even sophisticated encodings like CC1101 data whitening.
When it comes to protocol reverse-engineering, URH is helpful in two ways. You can either manually assign protocol fields and message types or let URH automatically infer protocol fields with a rule-based intelligence.
Finally, URH entails a fuzzing component aimed at stateless protocols and a simulation environment for stateful attacks.
This is free and open source software.
- Helps throughout the entire process of attacking the wireless communication of IoT devices.
- Supports a wide range of common Software Defined Radios (SDRs) with native backend or GNU radio backend.
- Scan the spectrum.
- Records signals.
- Import and edit signals.
- Demodulation – automatically performed when a signal is added to the Interpretation tab. Demodulation is the process of converting the recorded sine waves into bits.
- Spectrogram with FFT Window Size, Data (min), and Data (max).
- Supports filters – bandpass filter and moving average filter.
- Analysis – perform protocol reverse engineering.
- Break a wireless protocol with the Generator tab with fuzzing, modulation, apply encoding and modulating the bits.
- Cross-platform support – runs under Linux, macOS, and Windows.
