Receiving calls from "Apple Inc" stating that iCloud has been breached. Is this valid?

It is a common scam and has been going on a long time -- they just got to you now. Apple doesn't make unsolicited phone calls. If there was a problem you would be notified when attempting to log in, including when logging into this forum. Also see: Recognize and avoid phishing messages, phony support calls, and other scams - Apple Support

Also, the caller id number shown on scam and marketing calls is frequently not the number actually originating the call. The number is often spoofed.

One option to consider is Settings > Phone > Silence Unknown Callers. See: Detect and block spam phone calls - Apple Support

Hello,

• This is DEFINITELY NOT Apple, please immediately block this number, Apple would never contact you like this, you can learn more about scams at this link (Recognize and avoid phishing messages, phony support calls, and other scams - Apple Support).

They are crooks and just trying hard to make a buck (or a lot of them) by getting access to your money.

I no longer answer calls unless they are in my contacts. If they are legit, they will leave a message.
