Quote:A new variant of a recently disclosed SIM card attack method could expose millions of mobile phones to remote hacking, researchers have warned.
 
Earlier this month, cyber telecoms security firm AdaptiveMobile Security disclosed the details of Simjacker, an attack method that involves sending specially crafted SMS messages to the targeted mobile phone.

The attack relies on the fact that these special messages are processed by the legacy [email protected] Browser present on many SIMs. An attacker could issue commands to conduct various types of activities, including sending SMS messages, making phone calls, launching a web browser, and collecting information about the targeted device, regardless of operating system and manufacturer.
