That's the wrong threat model, though. The attack described is directly
against disk encryption. If the FDE key is exposed through a cold-RAM
skimming attack, there is no need to login to anything. The RAM is
skimmed, then the drive is imaged. Presto. Your data is toast.

This can be pulled off over a lunch break, and the only evidence would
be an unexpected reboot when the victim returns.
