Fantastic signals and where to find them

This talk with be an introduction to software defined radio (SDR) for security professionals with little to no experience in this topic. We are security professionals that started to explore the RF spectrum to look for vulnerabilities and will share our experience and learned lessons. We will look in some detail to our explorations in the portuguese RF spectrum such as: sniffing and manipulating Bluetooth Low Energy traffic, tuning into SIRESP (TETRA based emergency services network), looking at the signal for Via Verde (portuguese e-toll system), rolling your own GSM network and more. We will cover the basics of what you need to get started in this area and try to make a point that the RF space needs a closer look by information security professionals.
