While GSM firmware is designed to be secure, researchers and hackers have discovered various vulnerabilities and backdoors over the years. Some of these secrets include:

The GSM ecosystem was designed with a threat model focused on subscription fraud and eavesdropping, not nation-state adversaries or advanced malware. While the SIM card and network-side authentication have received extensive scrutiny, the —a separate CPU responsible for radio communication—remains a “black box” in most mobile devices.
