Paradigm Shift Publishes Unpatchable usbliter8 Exploit for Apple A12 and A13 iPhones

Summary
Paradigm Shift released a proof-of-concept for “usbliter8,” a Boot ROM exploit that can help unlock older iPhones using Apple’s A12 and A13 chips, including models from the XS/XR through the iPhone 11.
Physical USB access is required, but the flaw hits immutable code that runs first at startup, letting attackers clear an early barrier and potentially chain other bugs into a jailbreak or forensic hack.
Because the vulnerability is burned into the chip, Apple cannot patch affected devices through software; Paradigm Shift said moving to newer hardware is the most effective mitigation.
The disclosure does not make those iPhones trivially hackable on its own, since attackers still need additional techniques to reach user data, but it gives researchers and government contractors a valuable new building block.
The release underscores a broader reality for iPhone security: public jailbreaks have grown rare, yet sophisticated attackers still hunt hardware-level flaws that can outlast software defenses.
