Radio frequency (RF) remote controllers are widely used in manufacturing, construction, transportation, and many other industrial applications. Cranes, drills, and miners, among others, are commonly equipped with RF remotes. Unfortunately, these devices have become the weakest link in these safety-critical applications, characterized by long life spans, high replacement costs, and cumbersome patching processes. Given the pervasive connectivity promoted by the Industry 4.0 trend, we foresee a security risk in this domain as has happened in other fields.
