My Apple ID was hacked
Yesterday my Apple ID was hacked. I got a mail from Apple that someone logged into my account from a MAC device (it wasn’t me) and Apple advised me to change my password if it wasn’t me. It happened yesterday at 10 pm but I didn’t see it until today, 9 am. I went to change the pass but it wouldn’t send the code to my phone. I went to settings to check if my phone number was still written and it was. I somehow guessed my security questions and changed my password as well as removed the MAC advice from my advices. At 7 am I got many texts in chinese and I’m worried about what happened. Can someone help me? Pic of the messages attached
