This is the stuff of StingRay (IMSI catchers) and lawful interception.
: Unlike modern mobile operating systems, baseband firmware often lacks robust protections like Address Space Layout Randomization (ASLR) or Stack Cookies , making it an easier target for remote exploitation. gsm+secret+firmware
Once an attacker controls the baseband:
Assuming you are looking for to access firmware and GSM diagnostic data, Common GSM & Firmware Secret Codes This is the stuff of StingRay (IMSI catchers)
Beyond deep firmware hacking, "secret" access exists for everyday users through USSD codes . These are strings of numbers and symbols (like gsm+secret+firmware
