Learning to hack into systems? Then you’ll need a receiver of some kind to pick up traffic right? Why not try your hand on a HackRF One? Never heard of it? Well, I’ll have you know that this bad boy is capable of receiving and transmitting with a huge frequency range of 1Mhz to 6Ghz. This thing is slapped with a GNU Radio that makes it one of the easier and more popular devices to play with.
The things you can do with the HackRF are very vast and there’s always something new to discover. You can analyze traffic, sniff packets, view frequency’s and even match them. That’s a whole story that I won’t be touching upon but yes, if you know what you’re doing, you can do some crazy things. I definitely recommend picking one of these up and learning how to mess around with it. You won’t be disappointed. Although, they are a bit pricey.
