Has anyone experienced recent fraud issues with their CO Mastercards?

Within the last 6 weeks both of my accounts have been compromised,which is bizarre ,especially since these are not cards which I carry. They are basically used for CO tickets,car rentals and a utility company that requires MC.

Perhaps it is a coincidence,but these are the only two Chase cards having problems, of the 8 accounts we have open.

Chase is not very forthcoming with information.They simply close the account and issue new cards.
