On July 26 - Looks like my/our iCloud account has been compromised. I have a problem related to our Mac computers and use of iCloud that links all of our Apple/Mac equipment. It appears that almost every entry in our Address Book of a clearly financial nature - banks, credit cards, some on-line store accounts ( like Amazon ), etc. - has simply disappeared from our Address Books on both my MacBookPro and our iMac, from one day to the other, and only financial-related, not all the others entries.
...but curiously NOT from the Address Books on our two iPhones and one iPad, that, in principle, are linked to the computers via the iCloud??
Yes, we have changed all our usernames and passwords and checked that there has been no unauthorized activity on our accounts AND have removed all sensitive information from the Address Book. No unauthorized activity appears to have taken place, nor have any person's info disappeared.
However, we - and a Mac technician we know - are mystified as to how someone...or some hacking process...could just "cherry pick" only financial information from our Address Book.
We reach out to you to see whether anyone has any ideas, or suggestions...perhaps this has happened to someone you know, or someone knows of a Mac User Group that may be able to give info/advice.
