Service provider security breach warning
I received a letter from Amex today, dated Jan. 6 (!), advising that "a third party service provider engaged by numerous merchants experienced unauthorized access to its system>" It goes to say that my account number,
expiry date and security code may have been compromised. The account looks fine so far and no new card was mandated. Any idea what this might have been? I was wondering if it might have been related to the Hyatt problem....
