Apple's T2 Security Chip Has an Unfixable Flaw
Found on Wired on Wednesday, 14 October 2020
The flaw is one researchers have also been using for more than a year to jailbreak older models of iPhones. But the fact that the T2 chip is vulnerable in the same way creates a new host of potential threats. Worst of all, while Apple may be able to slow down potential hackers, the flaw is ultimately unfixable in every Mac that has a T2 inside.
The T2 also contains a vulnerability, known as Checkm8, that jailbreakers have already been exploiting in Apple's A5 through A11 (2011 to 2017) mobile chipsets. Now Checkra1n, the same group that developed the tool for iOS, has released support for T2 bypass.
Perfect security does not exist.
