Hacking of my personal email
Is it possible that someone has hacked my personal email account, to send me phishing emails from me, to me, without Apple noticing? The first time it happened last week I changed my password and set up 2 authentication system for logging in. It's happened again, today, with a different email message (this one basically saying give me money in exchange for not sharing personal details with the dark web) but I've had no notification of dodgy device sign in. How can this be?!
