KB Kookmin Bank said a review of its existing data breach increased the confirmed affected count from 119 to 2,210. The additional 2,091 people comprise 1,631 customers and 460 employees. This is an expansion of findings from the earlier incident, not an announcement of a new attack. Exposed fields can differ between individuals, so the same financial information should not be assumed to have leaked for everyone. Customers should check the bank’s individual notices for their status and affected data.
