Hello jack max!
Thank you for reaching out to the Q&A forum.
I understand you had your Xbox account hacked but regained access but are facing threats from the hacker, who claims they can use xbtools to "brick" your Xbox. I’m really sorry you’re dealing with this.
Beside the useful steps that Q&A has given above, here's how to contact Microsoft support to report the account compromise and threats and make sure the account is fully secured (review sign‑ins, remove unknown info, revoke access).
Go to: https://support.microsoft.com/home/contact
- In the search hox, type: Account security issue
- Hit "Get Help"
- Scroll down to choose Sign in to contact support
Then follow the on-screen prompts to reach Support Team.
Hope this helps your secure your account again shortly!
