I have an Apple ID with my real name, email adress and a phone number. I also have a Facebook account which is linked to that phone number. I also have a fake FB account registered under a different email adress and under a different name than my Apple ID, but the same phone number is linked to that account. Under my real account my phone number is set to not be visible to anyone on FB and so that no one can look me up using my email address. I’m not sure if I set it the same way on my fake account but probably not.
My apple ID was hacked first and then a week later my fake FB was also hacked and the password changed. It was the same person because they logged into my apple ID from Spain and when I tried to log into my FB it was all in Spanish.
I’m guessing they hacked my Apple ID by finding my phone number on my fake facebook and then they logged into my apple with my phone number and then later into my FB? But my real FB is under the same phone number with the same password and that one wasnt hacked.
