Wow...I've been seeing a ton of people asking this question wondering what the official word on this is myself. These seems like a huge potential issue. I know my iCloud has been hacked threw non-email phishing schemes that were very advanced and I've seen fake certificates used on the https://www.apple.com website when directly accessed. One time I called "AppleCare" and screen shared with some lady with a Jamaican sounding accent and the logo that started when the screen sharing thing began was a small white apple with like 1990s graphics. I told her it looks like it didn't work right and there's this messed up apple icon on my screen and she was dead silent. I know what I saw but Apple (customer service) still won't help me. They always just tell me to provide them with iron-clad evidence so someone with real technical experience can look into it.
Do you happen to be a computer expert or threat researcher with several hours on your hands who can clearly pinpoint low-level system corruption and present this information in an acceptably understandable medium to non-technical customer service professionals?
Be careful out there. Times are a changing.
