CFAA is a tractor beam they can use against anyone they don't like.
I work cyber security (well, mostly application security these days and not so much networking/telecomms) and I've also been involved with a small spat as a contractor a few years back. Basically, I had broken a collection source for the FBI by fixing and securing a resource for a certain department for a certain state, and maybe hypothetically it had to do with a very sunshiney state and maybe hypothetically it was a department that involved wheeled objects.
The firm I worked for was contacted by an investigator, which, lemme tell you, when an FBI agent appears at your work and asks your boss what sort of assignment you're working on, have no illusion that he's not about to cover for you in any way. Not that I did anything wrong. So anyways, the investigator asked me why I made all these WAN changes and about what packet filtering I had added/removed/reconfigured, all this technical domain knowledge and be really had a good idea of what I was actually doing. So I was comfortable. Eventually he left, basically saying we may be contacted further or potentially if the "investigation" became more serious, be made to appear in court.
Well the following week, a different guy comes in, and basically sealed me in our little coffee room and interrogated me. I was cooperative as I could be because I thought he was well informed like the other guy and generally had an understanding with my work, but he was a complete asshole.
It ended up that (thank God) all my paperwork was in order and my contract was pretty intensively detailed about what work I was going to be doing, I hired an attorney and he took good care of me. Never made it to court, but I ended up owing the lawyer a couple grand (funny how THEY always get paid) and yeah. Luckily I didn't go to federal prison, and my gratitude pushed me to greener pastures and better states.
TL;DR, your judgment has gotten you this far, so trust yourself, but I've poked the government before and I almost went to federal prison. Ymmv
