Barcelona-based offensive cybersecurity company, Paradigm Shift, has disclosed comprehensive details of an unpatchable security flaw affecting Apple's A12 and A13 chips. Dubbed "usbliter8," this vulnerability potentially opens the door for security researchers and government contractors to develop new jailbreak techniques for older iPhones, including models like the XS, XR, and up to the iPhone 11, which were released in 2018 and 2019.
Boot ROM Vulnerability Explained
The identified flaw resides in the iPhone's Boot ROM, the initial piece of code executed upon device startup, making it the device's first line of defense. Exploiting "usbliter8" requires physical access to the target phone, enabling hackers to potentially bypass subsequent security checks. For what it's worth, this disclosure highlights the enduring challenge of securing hardware-level components against sophisticated attacks. This development underscores the continuous arms race between security developers and malicious actors.

Implications for Older Devices
Given that the Boot ROM is immutable, meaning its code is permanently embedded in the chip, Apple cannot patch this vulnerability through software updates. Paradigm Shift suggests that migrating to newer hardware remains the most effective mitigation for affected users. While significant for the security research community, this revelation does not imply that older iPhones are now easily hackable by anyone. Attackers still need to chain this exploit with other techniques to gain access to user data stored on the device.
