Hello. My Microsoft/Xbox account was hacked and the attacker changed all of my account information, including the sign-in email and security information. My original email address was: ******@gmail.com My Xbox Gamertag was: Ayman27390

1. Start with the Microsoft sign-in helper tool for hacked accounts: Start. It asks for the original email address or phone number and routes to the correct recovery path or support option.
2. If access is still blocked, go to the Microsoft account Security basics page and use Review activity to check recent sign-in attempts. If suspicious activity appears, select This wasn't me for unusual activity entries or Secure your account for recent activity entries.
3. Change the password immediately if sign-in is still possible. Before changing it, run a full antivirus or malware scan on the PC. Microsoft recommends doing the malware scan first, then changing or resetting the password.
4. Check and update sign-in and verification methods:
   • Open Edit account info and add or remove email addresses or phone numbers associated with the Microsoft account.
   • Open Advanced security options and add another way to sign in or verify identity.
   • Keep phone numbers and email addresses used for verification up to date.
5. If the account email or phone was changed and sign-in is no longer possible, use the guided support tool mentioned on the account alias page.
6. If recovery is still unsuccessful, use Contact Microsoft Support from the Microsoft support page.

The screenshot also shows single-use codes and unusual sign-in alerts. Those are consistent with Microsoft account security notifications. Microsoft states legitimate unusual activity messages come from the Microsoft account team at ******@accountprotection.microsoft.com. Do not share single-use codes with anyone.
