Researchers extract the raw binary blobs from physical device storage chips or pull them out of official carrier software update packages.

This danger was brought to the forefront in 2017 when a root backdoor was discovered in several OnePlus phones. The culprit was an app called provided by Qualcomm to OEMs for factory testing. This app was partially exposed to users through the secret dialer code *#808# . By connecting a computer via USB (and with USB debugging disabled), an attacker could send a simple command to the OnePlus device and instantly gain root access, bypassing all security restrictions. OnePlus quickly removed the app after the disclosure, but it highlighted how a "secret" engineering tool could become a massive security liability. gsm+secret+firmware

Given that the baseband processor is essential for cellular connectivity, complete isolation is impossible. However, several steps can be taken to mitigate risk:

Cellular firmware is among the most strictly guarded intellectual property in the tech world. Manufacturers keep this code closed-source for several critical reasons: This danger was brought to the forefront in

These CVEs represent a constant arms race. They prove that the "secret" internals of baseband firmware are riddled with memory corruption bugs, length-field issues, and logic flaws that have persisted for years. As one researcher noted, "GSM code was developed in the 1990s, and its security comes from the same [time frame]... There's not much checking on input".
