Episode 16 – The Hostile SIM: Exposing the Hidden Attack Path in Cellular IoT
Every cellular IoT device relies on a Subscriber Identity Module, or SIM. But SIMs do more than identify devices on a network. Some can send AT, or attention, commands directly to the modem, controlling how it operates and creating a potential attack path. A “hostile SIM” could exploit vulnerabilities to: -Execute code -Read files -Downgrade connections to 2G -Take devices offline This is especially concerning for IoT devices that may operate for years without security updates. So, why is this legacy interface still open? And how can businesses protect devices already in the field? We’ve invited University of Birmingham researcher Dr. Marius Muench to break it down on this episode of “IoT Real Talk.” Learn more about hidden dangers lurking in cellular IoT: https://www.aeris.com/resources/hidden-dangers-lurking-in-cellular-connected-iot-devices/ Secure cellular IoT with Aeris IoT Watchtower: https://www.aeris.com/iot-watchtower/ Keep up with our IoT podcast: https://www.aeris.com/resources/iotpodcast/ Got questions, ideas or want to be a guest?
