I think people here will be really interested to know that this is an active technique in the "quantum hacking" world as well. As you probably know, quantum mechanics very often offers 100% security about creating shared keys which nobody else knows -- but there is a very active physics subfield called "quantum hacking" which says "well, but you're assuming that your device perfectly embodies these equations and the reality is it doesn't, so let's see what happens if we drive up the parameters to a non-ideal regime, can we run a Man-in-the-Middle attack then without you both knowing about it?"

Here's for example a pop-science article about using camera zapping on Vice Motherboard:

The solution to this was to include a filter which prevented oversaturation at the target wavelengths, but it turns out you could just blast it with some other wavelengths...

So it's a really fun-looking discipline, lots of groups hiring postdocs for it etc.
