Time Machine backup disk stolen from luggage... how big of a risk is this? This happened to a customer of mine. It was not an encrypted backup. She didn't have any Word docs called "Passwords for all my sites" or anything stupid like that. Nor did she have spreadsheets with financial account numbers or anything sensitive. Main concern might be gaining access to her Yahoo mail or logging into a financial institution's website. As far as I know a restored Time Machine backup won't retain passwords or sessions. If there is any risk it would require the skill of a computer forensics expert to do any damage. Right? But, within the same week her credit card was breached and her bank had her set up new security questions, security picture and new password. I'm having trouble connecting the two. Coincidence or not?
