This is just so odd as to almost not pass the smell test. Apple support gave access to a computer via a request: "am forget my password of mac,did you give me password on new email marko.[redacted]@yahoo.com"
Marko Karppinen isn't just anybody. He is the head of a Mac software development company. So it's not that the hackers got access to view his collection of fish pron, there probably was some important stuff. Apple didn't raise an eyebrow, sending out the new access almost immediately.
