One of the hardware features of Apple’s Mac computers is the T2 security chip. This chip allows the computer to decrypt and encrypt data on the fly, and it’s basically designed to help make Apple’s Mac computers and their data ever more secure.
Unfortunately, it doesn’t seem quite as invulnerable as Apple makes it out to be. Passware, a company specializing in password cracking tools, recently announced that their latest software can actually be used to defeat the T2 chip and bypass the brute force mitigations introduced by Apple.
Apparently, this is achieved by exploiting a vulnerability in the T2 chip that allows software to bypass the number of times passwords can be attempted. This means that attackers would theoretically have to use a password dictionary and brute force into the computer and decrypt its data.
However, brute force is all about probability, which means that depending on the length and complexity of your password, it may take Passware’s software a while to figure it out. Also, it requires physical access to the Mac and only works on Intel-based Macs, so it’s not the easiest hack for the most part, so it’s reassuring to know.
