Device Security Attacks

Attacks targeting device-level security features including unlocking, identity tampering, and detection bypass mechanisms.

Firmware Attacks

Low-level attacks targeting bootloader, firmware, and secure boot mechanisms that operate below the operating system.

Authentication Attacks

Attacks targeting device authentication and integrity verification systems including SIM locks and security frameworks.

Hardware Attacks

Physical attacks involving hardware modification, component replacement, and tamper detection mechanisms.

Baseband Attacks

Attacks targeting the baseband processor firmware and internals, including remote code execution, firmware backdoors, and baseband processor exploitation.

RAN Attacks

Attacks targeting the Radio Access Network (RAN) interface, including radio protocol manipulation, network spoofing, protocol downgrade attacks, and man-in-the-middle attacks on cellular communications.
