Security Breach

I received a phone call (Robocall) from 800-275-2273 today about a security breach. I can't remember what all it said, but it mentioned that I should not sign into any banking, etc because of the breach. I had the option to press a number to connect or to call an 877 number. I didn't get the rest of the number because by then I was freaking out. I immediately shut down my computer and called my son because he has an Iphone and I wanted to see if he got a similar call, which he didn't. I finally turned on the computer and am writing this to see what is going on. When I called the 800 number, it appears to be an Apple Support number, so that would mean the call must have come from Apple. Isn't that correct?
