Well I would not use the box for code development. This is a RAID array for
the home theater. The source code is going to be managed on SourceForge and
there is a firewall between my office and the rest of the house.

Yes it is.
Which is why I do not have any connection to the operational environment.
I am very interested in open source HSM efforts. But that isn't currently
What is in my scope is considering supply chain security and the risks of
precisely this type of compromise. I do build my development machines
myself but that only ups the work factor rather than being a protection. I
like these Raspberry Pi devices as I can load them with an O/S build of my
choice from a reasonably secure media. Again, not perfect proof.
Thing is that I have attended MIT workshops where we discuss this sort of
thing with people who retired from the most senior positions of certain
three letter agencies. One of the hypotheses I put forward at that meeting
1) China has good reason to fear cyber attack from Russia (look at a map,
all those countries between them are highly unstable and have large Russian
and Han minorities)
2) China's policy of stealing IP has prevented the country developing a
native design capability. We hire lots of Chinese engineers who can't find
work at home to do anything apart from reverse engineering.
3) Therefore, China has to get the US/Germany/etc. to do the R&D for the
cyber defense technologies it needs so it can steal them.
4) China has no purchasing power because it steals everything.
5) Therefore China's optimal cyber strategy is to attack the West in the
very open manner we see in the expectation that this causes us to develop
the cyber defense technologies they need.
So maybe they are just attempting to use the strategy I suggested to apply
my thought to the supply chain problem they would like to see me solve
rather than the other problems they do not want to see solved.
