I figured I should post there here. Per the message I received from Spekulatius the hacker used the below email and IP address

The attacker used the email
screams@live.com and the IP 73.166.140.216.

I received the same PM , however welcome back @Spekulatius. ( I hope you're not coming to use again GMX or web.de). I simple gmail address with the 2FA it's the better solution and obviously secure .
Ok, changed it to a yahoo.de account. Hope thats secure enough

Feels good to be back
That may work, however the most secure email would be one that cannot possibly exist (IDK why the forum does not allow the option of simply not having an email at all). What I recommend using is [username]@bitcointalk.org, since the forum does not offer email services it would not be possible to hack/create that email address (although you would be somewhat out of luck if you forgot your password)
