APFS encrypted device with T2-Chip

[Zen6]

Hi digitalhussar,
can you share your information about extracting the keybag out of a T2 chip?
Are you attacking over the Thunderbolt PCIe lines or over the USB debug port and chackm8/blackbird?
I'm struggling for months on a MacBook Air 2020 and am thankful for any idea.
Thanks
