This is the stuff of StingRay (IMSI catchers) and lawful interception.

Detecting hidden firmware is notoriously hard, but researchers have identified several methods: Technicians use specific tools to interact with device

This article synthesizes research from public DEF CON talks (notably by security researchers like Karsten Nohl and Ralf-Philipp Weinmann), leaked NSA ANT catalog documents (specifically "IRATEMON" and "MONKEYCALENDAR"), and modern forensic vendor white papers.

The concept of "GSM secret firmware" is most famously linked to phone unlocking. Since the lock is enforced at the baseband level, any method of overriding it must operate at that same deep level. These methods can be broadly categorized as software unlocks, hardware/engineering unlocks, and the use of secret dialer codes. These methods can be broadly categorized as software

The secrecy surrounding GSM firmware has several implications:

The baseband processor trusts data coming from cell towers implicitly. If an attacker sets up a rogue cell tower (known as an IMSI Catcher or Stingray), they can broadcast malicious radio signals. If the GSM firmware contains a buffer overflow vulnerability, the rogue tower can execute code on the baseband processor without the user ever clicking a link or downloading a file.
