Got phone call that iCloud account was breached

Apple does not make such calls.

All such calls are scams from criminals attempting to steal your personal and financial information. The callers will often use number spoofing to pretend they are calling from a legitimate business. The correct course of action is to ignore the calls or hang up on them, repeatedly if needed.

I also just got the fourth phone call/voice mail this afternoono from four different local telephone numbers alerting me of a breach to my iCloud account and not to log into my account on any device. Told me to call ***-***-8257. I didn't call.
