The news isn't especially great for travelers during security checks at border crossings or for enterprises that employ large fleets of Macs and MacBook notepads, all of which are now exposed to attacks and having their secrets pilfered in classic evil maid attacks. Any Mac or MacBook left unattended can be hacked by someone who can connect a USB-C cable, reboot the device, and then run Checkra1n 0.11.0. The danger regarding this new jailbreaking technique is pretty obvious. This allows an attacker to get root access on the T2 chip and modify and take control of anything running on the targeted device, even recovering encrypted data. "Using this method, it is possible to create an USB-C cable that can automatically exploit your macOS device on boot," ironPeak said.

Per ironPeak, this works because "Apple left a debugging interface open in the T2 security chip shipping to customers, allowing anyone to enter Device Firmware Update (DFU) mode without authentication."

This works because of some shared hardware and software features between T2 chips and iPhones and their underlying hardware.Īccording to a post from Belgian security firm ironPeak, jailbreaking a T2 security chip involves connecting to a Mac/MacBook via USB-C and running version 0.11.0 of the Checkra1n jailbreaking software during the Mac's boot-up process. The attack requires combining two other exploits that were initially designed for jailbreaking iOS devices - namely Checkm8 and Blackbird. Over the summer, security researchers have figured out a way to break T2s and found a way to run code inside the security chip during its boot-up routine and alter its normal behavior. In other words, they have a significant role in every recent Apple desktop device, where the chips underpin most security features. However, they also serve as a "security chip" -as a Secure Enclave Processor (SEP)- that processes sensitive data like cryptographic operations, Ke圜hain passwords, TouchID authentication, and the device's encrypted storage and secure boot capabilities. By default, they handle audio processing and various low-level I/O functions in order to help lift some load off the main CPU. Their role is to function as a separate CPU, also known as a co-processor. T2 chips were announced in 2017 and began shipping with all Apple devices sold since 2018. What are T2 chips?įor Apple users and ZDNet readers that are not aware of what T2 is, this is a special co-processor that is installed alongside the main Intel CPU on modern Apple desktops (iMac, Mac Pro, Mac mini) and laptops (MacBooks).

If exploited correctly, this jailbreaking technique allows users/attackers to gain full control over their devices to modify core OS behavior or be used to retrieve sensitive or encrypted data, and even plant malware.
