If you put all your eggs in one basket, watch that basket. Or others will.
What leads me to this statement? “Apple Will Investigate Celebrity Hackings,” Wall Street Journal, September 2, 2014 B6. Photos and videos that celebrities had posted to their own iCloud accounts got hacked and published. Not sure yet whether it was password compromise or a deeper security problem with iCloud.
Is there information you don’t want others to see? Don’t post it anywhere in the cloud. You may even wish to encrypt it on your hard drive and any other places it is stored, if you store it on/in a connected device. This applies equally to videos of yourself and to sensitive corporate information — the common elements are: 1. Sensitive information; 2. Electronic storage; 3. Users who don’t understand (or appreciate) the risks.
