From a comment on the article
> Looks like one of the Thunderbolt ports on the right-hand side, probably the one closest to the headphone jack, is connected to the T2 by way of a USB switch. This is probably the port that is used to perform a DFU restore of the iBridge, like on the iMac Pro ( https://help.apple.com/configurator/mac/2.7/#/apdebea5be51) It’s possible that data recovery could also be performed via that Thunderbolt port given the right tools.
The T2 ARM coprocessor secure enclave with encryption keys is connected to an external PCIe bus that is also connected to the main x86 CPU? Is there a risk of DMA attacks like PCILeech? What policy restricts devices that can pair with the T2?
