If Sony knows exactly how they broke in (hacked it) ... they are not going to make it public knowledge and announce the details to the media ... besides the fact that it is an on-going FBI investigation.
I have used Macs for many years with no problems. Got a new iMac last January, and although I love it, it has stopped recognizing a couple of my passwords, namely gmail and iCloud. Can’t figure out why. Always happened overnight. I’d shut down in the evening, and next morning upon turning it back on, I had problems. I have no clue!
