Hi, first time submitting to this community. So basically, some hacker got access to my email, and began trying to transfer a bunch of accounts to his email (venmo, paypal, riot, blizzard, etc.). He successfully transferred the ones that were not 2fA. Thankfully, I caught on while he was in the process of doing it, so I changed all my passwords and set up 2fA on a bunch of accounts.
I was wondering what I could do to take some revenge/justice using IP addresses that steam gave me when he tried changing account things. I have two IP addresses he was using, two in completely different locations so I am unsure if they are from VPNs or not. I also have the gmail account that he transferred all of the stuff onto. I am not very experienced in this kind of stuff, so I am looking for guidance. How could I report him to authorities? What do you guys think?
