Question: Is email@example.com a legitimate email address?
I received an unusual email from "firstname.lastname@example.org" on 9/24 stating that my iCloud account had been used to sign in to a MacBook Pro 13" on the West Coast named "macen" - I did not click on the link in the email (https://appleid.apple.com/) but navigated there to change my password from safari on my phone. I also discovered that I had about 50 texts to various numbers in China.
Is this a legitimate email I received? I was reading about John Podesta's email hack and I thought the m.o. sounded similar to mine (early-morning weekend notification, legitimate-looking email, panicky decision) - any guidance or input would be most appreciated!
