Job description

Description

A vendor producing a lot of wireless-enabled System-on-Chips (SOCs) used in various IoT devices, developed its own wireless mesh network which they advertise as a proprietary "Bluetooth Mesh" protocol. The vendor provides a Bluetooth Low Energy gateway, that has already been reverse-engineered and documented, to access the custom mesh network but their own custom protocol, used to make devices communicate over the air, still remains a black box.

We want to open that box and look inside.

What you will do

In this internship you will:

  • Reverse-engineer and document the vendor's mesh network protocol, using both an off-the-shelf Bluetooth Mesh smart bulb kit and the vendor's Bluetooth Mesh Starter Kit
  • Search for vulnerabilities in the mesh protocol implementation and develop one or more proof-of-concepts
  • Add support for the propietary mesh network protocol to WHAD, and develop dedicated tools for recon and exploitation
  • Present your research project internally to peers, communicate it publicly in a blog post, paper or conference talk.
Profile
