Compromising Apple ID

Greetings! My name is Kostya, I'm from Russia, a couple of years ago I registered an Apple ID account. But I did not use it, nevertheless I use the mail that this account was created for. Recently, messages started coming to my email that the MacBook Pro 15 used iMassege from my ID, then another MacBook repeated the same thing. I logged in to Apple ID oddly enough using an old password and saw three laptops I didn't know ever. Immediately changed the password, but did not think to look at the find iPhone check whether they are in the account. After some time, I deleted these MacBooks. Question: Can I find out from which point the attackers connected to my compromised account?
