Hi! I’m sorry to hear about your situation. Please note that for security and privacy reasons, Microsoft cannot provide the names or personal details of individuals associated with IP addresses. What you can do is gather all available information such as the suspicious login attempts, the dates, times, and IP addresses (you can find these in your Microsoft account security page under “Recent activity”), and share them with your local law enforcement. They have the authority to request further details through the appropriate legal channels, if necessary.
In the meantime, I strongly recommend that you immediately secure your account by changing your password, enabling two-step verification, and reviewing your account recovery options to make sure they are accurate. You should also check your devices for malware with a full antivirus scan.
