Wouldn't this be possible for anything on the PCIe bus?  Presumably it
can just directly access either RAM or the hard drives or the ethernet
controller.

I'm not sure if typical x86 hardware+OS uses IOMMU to protect against
something like this.

I'd be skeptical but Bloomberg is pretty reputable.

You couldn't just stick it in a keyboard cable though.  It would
obviously have to attach to a bus of some kind with sufficient access.
