Re: DAMN YOU DIGITAL TRANSFORMATION!!!!
Whenever you hear the word "transformation" in any management speak you should expect the worst. It is a by-word for pain and often for little on no gain.
Almost certainly the issue for our French cousins is much like the NHS and others: where critical systems are not well (if at all) segregated from those with email/web/USB access for various reasons. Not sending on proper network planning, firewall settings and disaster containment/recovery are likely to be the big factors. Yes, it is also often a Windows-only issue, but a lot of essential software or very high value hardware (MRI scanners, etc) needs that and so you have to deal with it but limiting what happens when either a zero-day exploit is used or (more likely) someone makes a dumb mistake.
