Investigating Foreign Tech from Online Retailers

Recon Village @ DEF CON 338th, 9th and 10th August 2025

Abstract

We live in a time where we can buy practically anything online. It's very tempting to buy cheap products online, including electronics. While saving money can be great, what are we really getting here? Where did it really come from, is it safe to use, and what is really going on behind the scenes? Let's find out!

In this talk, we'll track the supply chain of a foreign smartwatch on Amazon using various OSINT techniques. After going down the rabbit hole, we’ll perform a hardware/software breakdown with automated and manual analyses (and further OSINT based on our findings). By the end of the talk, you will have a better understanding of some of the tools and processes you can use for performing your own due diligence.
