Demystifying phone unlocking tools: A technical overview

Commercial phone unlocking tools exploit well-known vulnerability classes rather than novel techniques, but systematize their exploitation across different hardware and software combinations into automated workflows. These tools target specific attack surfaces in mobile devices' hardware security architecture, particularly the boot chain, trusted execution environment, secure element, and kernel driver stack. The article provides a technical overview of how forensic tools compromise Android and iOS devices, with focus on components like TrustZone partitioning, Gatekeeper credential verification, and Keymaster key management services.
