Good News, Bad News for Apple T2 Security Chip Users

October 13, 2020

Glad you paid that premium price for the latest and greatest Apple device? Not so fast. Ars Technica reported that Apple's T2 security chip has a bug that can't be fixed. A tool has been released that allows anyone to bypass Apple's T2 security chip on a Mac to gain deep rooted access to the system. It's the same vulnerability that has been exploited for over a year with older iPhones. As Ars stated, "…while Apple may be able to slow down potential hackers, the flaw is ultimately unfixable in every Mac that has a T2 inside." Bummer.

The bad news is that the T2 security chip doesn't really secure your device. The good news is that it takes a little work to take advantage of the vulnerability. The attacker must have physical access to the device in order to run the jailbreak tool. More good news is that the attacker won't have access to encrypted data, however, they could install a keylogger to gather the decryption key(s) to ultimately expose encrypted information. As we've always said…there is NO 100% security.
