Can You Trust Me Now? An Exploration Into the Mobile Threat Landscape
summary
Survey of the full mobile stack identifies where real risk lives: Qualcomm dominates SoC market (≈60–70% share), OEM/carrier Android forks cause update abandonment, and iOS stays current (near latest releases). Trusted hardware layers — TrustZone and baseband hold the keys — expose cross-device, cross-OS exploits; secure boot, QFuses and modems are attack targets. Physical probing costs ~\$2k for lab gear. MDM sits high in the stack and fails if lower-level trust is broken.
