Affected Models: iPhone XS, XR, 11 lineup, iPhone SE (2nd gen), select iPads, and Apple Watch Series 4 and 5.

How Usbliter8 Works:

Physical Requirement: Requires direct physical access and a wired connection via a dedicated microcontroller (such as an RP2350-based board) while the device is in DFU mode.
Boot-Chain Compromise: Executes malicious code in under two seconds during startup, overriding standard security checks before the operating system boots.
Unpatchable Nature: Because the vulnerable code is hardwired into the immutable silicon SecureROM during manufacturing, Apple cannot fix it through standard software updates. Upgrading to newer hardware (A14 chips or later) is the only complete mitigation.
