Hey all I'm new here 2 or 3 months and I found something out today I thought that I would post to get an opinion I was at my aunts today and she tells me that her neice(14) had some guy that was chatting with her and after a little bit he sends here a pic of him in the nude and tells her to send one of her butt see refused and he told her that he would hack her system and shut her down (which he did). Now as far as i could get from my aunt he got her to give him her ip before this all happened. Obviously these people are causal internet users.
and I have not talked to them as of yet their going to call me later so we can get together

My question is what would be the first things to check to get her system back up for her so I can at least secure it a little better for them. They have no security on the system.

second which authorities should she contact the guy said he was out of state. can anything be done

third this is the opinion Q that has been explored before here and in the tech school that i am in should I try to find this guy on my own just because.

I am in know way a hacker or any of the other of those types i am in school with the hopes of getting in to the field of system security/network security so i can use this as a learning exersize.

any help or opinions are welcome thanks for any help
