If you’re a researcher or enthusiast looking to explore GSM internals:
To understand secret firmware, one must first understand the phone’s architecture. Every GSM phone contains two separate computers: the Application Processor (AP), which runs your apps and user interface, and the Baseband Processor (BP), a dedicated chip that manages radio communication with the cell tower. The BP runs its own real-time operating system (RTOS) and its own firmware—a set of low-level instructions. gsm secret firmware

at the Security Research Labs (SRLabs) revealed that secret firmware lacks modern security protections like ASLR (Address Space Layout Randomization). This allows attackers to send "silent" SMS messages to execute code on the baseband processor without the user ever seeing a notification.
