need phone factory reset remotely getting hacked

Could you explain a little more about what is happening, what sort of hack is showing up and how, and can you confirm that your Apple ID password is secure and is unique and not re-used, and whether or not two-factor authentication is enabled on your Apple ID?

In general: If you think your Apple ID has been compromised - Apple Support

I ask the above because there are a number of scams around that claim hacks have happened, when that was not the case.
