Eth(er)ical Hacking – Hacker Defined Radio and analysing Signals
There is a lot going on in the wireless world. 5G is all the fashion, because frequencies are being auctioned. This is only the tip of the iceberg. Wireless protocols have become ubiquitous. The IEEE 802.11 family is one widespread example. Bluetooth, mobile networks, ZigBee, Z-Wave, and other wireless transmissions are widely used. If you go looking for signals, your first stop are usually industrial, scientific and medical (ISM) radio bands. But there is much more. It’s well worth to passively scan what’s all around you. The equipment is often the main obstacle preventing hacker from doing something. When it comes to radio waves you need a suitable antenna (or a couple thereof) plus the hardware to drive it. Even if you limit yourself to passive operation you still need something to catch, amplify,
