Apple ID compromised

Was at school today when I got a text message which contained a bunch of Chinese letters. Translated it and it said something like “your mother is dead, everyone in your company must die”. I forgot to screenshot the number and I deleted the text message because I wasn’t thinking straight.

Came home to find that my Apple ID was used to sign into I message using a MacBook Pro 15. I changes my password and checked my account for any activity, but it turns out no transactions were made (because I had no method stored) and the device didn’t show up on the section which shows devices that are signed into your ID.

Created this post to see if anyone got a similar message and also to let everyone know how easily my account was compromised. Also if there’s anything else I should do in order to make sure they definitely don’t have access to the account and to make sure this won’t happen again anytime soon.
