Hacking and auditing LoRaWAN networks

IoT deployments just keep growing and one part of that significant grow is composed of millions of LPWAN (low-power wide-area network) sensors deployed at hundreds of cities (Smart Cities) around the world, also at industries and homes. One of the most used LPWAN technologies is LoRa for which LoRaWAN is the network standard (MAC layer). LoRaWAN is a secure protocol with built in encryption but implementation issues and weaknesses affect the security of most current deployments.

While there is already prior research on LoRaWAN security most of them focus on known protocol weakness and theory, none of them provides tools neither examples of common security problems of real deployments.

Currently there are not guidelines neither tools to test the security of LoRaWAN networks, if someone wants to audit a LoRaWan network she has to start from scratch. Over the last year we have been researching LoRaWAN to identify common security problems and building tools to test LoRaWAN networks security.

In this talk we are going to describe the common security problems we found on LoRaWAN deployments. Also we are going to provide step by step guidelines on how and what to test on LoRaWan networks indicating what hardware and software to use, also we will be releasing new tools to test the security of LoRaWan networks. Finally, we are going to provide recommendations for secure LoRaWan deployments.
