Cloning basic Keyfobs using GNURadio and an SDR!
In my introduction to hardware hacking, I mention that radio systems may be part of the attack surface for a hardware device penetration test. So I thought I’d give a gentle introduction to hacking with an SDR here!
Firstly, what’s an SDR? It stands for software-defined radio, and refers to a category of devices which allow you to interface with radio. There are a lot of SDR devices on the market to choose from when you first get started – a RTL-SDR can be picked up for £15 and devices from Ettus Research go well into the thousands of pounds.
