[binary] TPMs and Baseband Bugs

This week we go a bit deeper than normal and look at some low level TPM attacks to steal keys. We've got a cool attack that lets us leak a per-chip secret out of the TPM one byte at a time, and a post about reading Bitlocker's secret off the SPI bus. Then we talk about several Shannon baseband bugs disclosed by Google's Project Zero.
