Researchers examine attack risks from manipulated SIM cardsA study tested 26 devices and found potential access to smartphones, vehicles and industrial facilities.
- Researchers from the University of Birmingham and Fuzzware used the CATana tool to examine 26 devices, including 18 smartphones and eight cellular modules, and are presenting their findings at the USENIX WOOT 2026 security conference in Baltimore.
- The Proactive SIM function can allow a SIM card to send AT commands to the cellular modem, and several tested devices accepted such instructions, potentially activating disabled functions or exposing sensitive information.
- In testing, manipulated SIM cards could downgrade connections from 4G to the less protected 2G network and, on newer Android devices, open an attacker-controlled webpage without input even when smartphones were locked.
- The researchers notified the GSMA and affected chip and device manufacturers, after which several companies responded with software updates and stricter configurations.
The attacks we found scratch only the surface of what is possible with malicious SIM cards— Tomasz Piotr Lisowski, University of Birmingham, in relation to the SIM security study
