Session
Disagree with the latest price hikes of your local store? Then this talk is for you!
As price labels, commonly called electronic shelf labels (ESL tags), play a major role in store architecture, they increase the potential attack surface and attract attention from adversaries. To understand how these products work, we examined Android apps, web-based management software, Bluetooth Low Energy (BLE), and 2.4 GHz traffic, as well as their hardware components. In the process, we identified architectural and implementation weaknesses across every part of the ESL infrastructure.
