In this talk, we'll review some of the wireless protocols and signals produced
and consumed by our modern tech devices and infrastructure around us.
Furthermore, we'll explore the privacy and security implications of some of
these protocols.
No prior knowledge about wireless protocols or signal analysis is required. We'll explore signals live both with an SDR (Software Defined Radio) as well as cheap consumer devices.
During the presentation, we'll have a quick introduction on the glossary of
wireless data transmissions, just enough to have a common understanding for
what's coming next. From there, we'll explore some of the RF signals
surrounding us daily, from old school analog radio all the way to modern
communication stacks like Wi-Fi, BLE, LoRa, ZigBee, etc.
For some of these protocols, like BLE (Bluetooth Low Energy), ZigBee and
others, we'll dive deeper into the privacy implications of using them. From
smartwatches beaconing our location to IoT sensors leaking information.
Additionally, we'll expand on the hardware needed to interact with these
protocols.
SRE by trade, but my interests lie in security, decentralization, radio communications and hardware hacking.
