We were hacked, by sons old girlfriend who was extremely good at cracking anyone’s password. A few years later by Russian group. We had to change router, emails, passwords on all accounts. You name it we did it. Everyone one was alerted, to include Cox, ATT etc. it is a mess. I am glad to see that several people here gave you some strong sites to check out. All I can give you is luck that you can get through this and find them.....now the one thing and I honestly don’t know rules or laws...but maybe get ahold of a university computer professor and they may beable to give you legal leads to go on.
