One tech ransom case I know of was an inside job. It definitely happens.

There are already significant penalties for doing anything like this. The guy involved is in prison for a very long time. I don’t recall the exact number of years but I do remember it was so long that he wasn’t going to see his kids grow up.

I don’t think anyone who puts a little thought into a crime like this doesn’t understand that the penalties are already very huge. You don’t get a slap on the wrist for extorting a company (or person, for that matter)
