Tencent Xuanwu Labs has successfully breached the latest MacBook equipped with the M1 chip and the iPhone 12 Pro using newly discovered security flaws, according to Tencent Security.
This may be the first publicly available security flaw that can affect Apple M1 chip devices.
Tencent Security said it recently discovered that by exploiting a vulnerability of the M1 chip, it is possible to bypass the system's restrictions on app permissions.
The team demonstrated the upgrade from normal to root privileges on a MacBook using the latest Apple M1 chip.
The version number of the system on the device is macOS Big Sur 11.0.1, the device model is MacBook Air (m1, 2020), and the chip is M1.
Tencent also demonstrated that after disabling an app's access to albums and contacts on iOS, the app can still read the phone's albums and contacts and upload them to the server. The device model is iPhone 12 Pro, iOS 14.2.
Apple recently introduced the first in-house developed Mac chip based on ARM architecture, M1, with an 8-core central processor, 8-core graphics processor and 16-core architecture neural network engine.
Its CPU, GPU, machine learning performance, and energy efficiency are all significantly improved over previous products.
The Apple M1 chip is built on the industry's most advanced 5nm process with 16 billion transistors. Apple's MacBook Air, MacBook Pro 13-inch, and Mac mini are the first to feature the M1 chip.
