I know some people who work for a TSMC subsidiary- they take security extremely seriously, all data is physically located in Taiwan and everyone remotes in, super locked down systems, etc.
I can’t imagine their actual production floor being connected to anything at all, ever. You’d need a stuxnet style airgap jump.
It seems that possibly now is a chance to data breach thanks to their fab expansion plan to overseas.
Those companies have state level adversaries to contend with.
Chinese hackers already hacked the NSA and stole their zero day exploits - it was 2014 but still.

Yep..MS just had to send out a 'security update' to provide them with a few new vectors.
