To keep up with the growing demand of always-on and available-anywhere connectivity, the use of cellular, in comparison to its wireless mobile connectivity counterpart in the electromagnetic spectrum, is rapidly expanding. My research in the IoT space led me down the path of discovering a variety of vulnerabilities related to cellular devices manufactured by Sierra Wireless and many others. Proper disclosures have occurred; however, many manufactures have been slow to respond. This led into examining numerous publicly disclosed vulnerabilities that were considered "low-hanging-fruit" against cellular devices and other cellular-based network modems that are often deployed as out of band management interfaces. The research expanded through the details provided in configuration templates available by each device including the following:
Focusing on an obfuscated series of examples to protect the organizations, people, and companies identified; this presentation focuses on the services and systems information of the following, commonly deployed cellular-connected devices to provide an in-depth look at what is easily possible:
