- Unpatchable 'usbliter8' Exploit Breaks Apple A12 and A13 SecureROM Boot Chain
Security researchers at Paradigm Shift discovered an unpatchable exploit named usbliter8 that allows arbitrary code execution in the SecureROM of Apple's A12 and A13 chips. The flaw exists in hardware and cannot be fixed via software updates, affecting devices with these chips indefinitely. The attack requires physical access and is not remote.
- Researchers drop checkm8-style BootROM exploit for A12 and A13 iPhones
Researchers at Paradigm Shift disclosed a BootROM exploit named 'usbliter8' affecting Apple's A12 and A13 chips, which cannot be patched as it resides in immutable SecureROM code. The vulnerability allows attackers with physical access to run unsigned code and bypass security measures during the boot process, impacting devices like the iPhone XS, XR, 11, and 11 Pro. Apple was informed of the findings, but no fix is available for affected devices.
