Security researchers from the University of Birmingham and Fuzzware have discovered that malicious SIM cards can execute attacker-controlled commands on cellular modems, potentially compromising IoT devices including EV chargers, industrial routers, and vehicle telematics systems. Testing across 26 phones and cellular modules confirmed this vulnerability exists in critical infrastructure component
A malicious SIM card can order the device it sits in to run commands of the attacker's choosing. On the cellular modules built into electric-vehicle chargers, industrial routers, and car telematics units, that is enough to take the whole device over. Researchers at the University of Birmingham and the security firm Fuzzware tested 26 phones and cellular modules for the capability, found it
