Camera hacks, any updates?

The last thread I saw on this ended in 2016.

I received what can only be described as a threatening email claiming a virus had been implanted and my camera had been hacked. The claim made was pretty weird, the language was non-native english (and not related to being from Belgium as the writer claimed; the email address country code was Hungary, surely nothing valid about any of it), and no mention was made of what my OS was, or anything specific to the machine or device of mine said to have been hacked.

Of course **** sites were mentioned, they claimed to have accessed my address book, etc, and bitcoin was demanded. Their threat was to send a video out to my address book contents.

It most resembled what I have heard about ransomware emails. Surely I could have done something in front of my camera that would be embarrassing at some point or points, who can be sure, especially with the advent of sw methodology to edit faces onto other bodies, etc.

One odd thing was that the email address used to reach me is not one I use many places. We have our own domain and make up unique addresses for leaving at sites, etc.

Does the light come on with any activation of apple/mac cameras, or can that be circumvented?

Has anyone heard of an iPad, iPhone or Macbook camera hack, recently? If it is something possible on any Apple devices then I'll have to use tape on my camera when orgies are going on, or I'll have to cut back.
