A security vulnerability that cannot be patched has been disclosed in Apple’s A12 and A13 chips, drawing renewed attention to the potential for jailbreaking and further hacking research on older iPhones. Barcelona-based offensive cybersecurity firm Paradigm Shift released the flaw, dubbed “usbliter8,” along with proof-of-concept code and technical analysis. The issue resides in the BootROM, which runs first at startup and cannot be fixed through software updates, though exploitation requires physical access.
