By [email protected] (The Hacker News)

AI Summary

Researchers at the University of Birmingham and Fuzzware tested 26 phones and cellular modules, finding that a malicious SIM card can inject attacker-controlled commands directly into the modem firmware of devices — including EV chargers, industrial routers, and automotive telematics units — sufficient to achieve full device takeover. This supply-chain-level attack vector requires no network access from the attacker beyond physical or logical SIM insertion, posing significant risk to IoT deployments across critical infrastructure.
