In actuality, the SIM card in your phone is actually a small computer, with memory, a processor, and even an operating system. As you can see in the diagram below, there is a chip beneath those gold contacts, and on that chip there is a processor, ROM (firmware that stores the OS and SIM apps), EEPROM (which stores your phone book, settings, patches), and RAM (for use by the SIM’s OS and apps). In this case, modern SIM cards run a very simple OS that loads up Java Card — a version of the Java virtual machine for smart cards (of which SIMs are a variety of). Java Card essentially runs small Java applets, and each applet is encapsulated and firewalled (sandboxed) by the Java VM, preventing sensitive data from leaking to other apps.
Your phone interacts with these apps via the SIM Application Toolkit (STK) to display information on your screen, and to interact with the outside world.
To load apps onto the SIM or to update them, hidden text messages are sent by the carrier, containing over-the-air (OTA) programming in binary form. These messages are signed with a cryptographic key, so that the SIM knows that these messages have originated from a trusted source.Now, German security researcher Karsten Nohl has discovered a way of finding out that all-important cryptographic key. By sending his own OTA SMSes that aren’t signed with the correct key, he discovered that some phones pop up an error message that contains a cryptographic signature. Once he had this key, he could send apps and viruses to the SIM card that can send premium text messages (racking up huge bills), re-route or record calls, collect location data — you name it, with access to the SIM, you can do just about anything.
