Hi, 지수 공
Good day!
Thanks for posting into our community and we're glad to assist you.
According to your description, I'm really sorry to hear about the trouble you're experiencing.
First of all, would you please allow us to collect some detailed information as below:
- Could you please tell us which of your accounts is being subjected to identity theft and virus hacking?
- Can you also let us know what type of account is being targeted? Whether if it's a Microsoft 365 business account(@xxx.onmicrosoft.com/@yourdomain.com) or a personal account (ending in outlook.com/hotmail.com/live.com/msn.com) or another third-party POP/IMAP account?
If you're using an Office 365 for business account and it's being subjected to identity theft, please contact your administrator the sooner the better. Your organization's administrator reset MFA immediately - Microsoft Entra 다단계 인증을 위한 인증 방법 관리 - Microsoft Entra ID | Microsoft Learn.
Follow the Microsoft Official instructions - 손상된 전자 메일 계정에 응답 - Microsoft Defender for Office 365 | Microsoft Learn and then report it to Microsoft.
Thanks for your understanding and cooperation.
Hope you all the best.
Sincerely,
Alex | Microsoft Community Moderator.
