New Apple Exploit Exposes Millions of iPhones Worldwide, No Software Fix Available

**Executive summary:** Paradigm Shift disclosed "usbliter8", a hardware/firmware exploit that abuses a Synopsys DWC2 USB controller DMA handling and SecureROM DART configuration on A12/A13 (and some S‑series) Apple chips to bypass secure boot and achieve privileged code execution (requires DFU mode and specialized USB hardware); affected devices include iPhone XS/XR/11 series and Apple Watch Series 4/5, the flaw is unpatchable in silicon so mitigation is device replacement and physical-security controls.
