The contractor, who has been arrested, allegedly sold the stolen information to marketing firms, the BBC reports. Compromised information includes names, Social Security numbers and credit card details.
The three credit card firms affected by the breach are KB Kookmin Card, Lotte Card and NH Nonghyup Card. Regulators are looking into the security measures in place at the three companies, according to the BBC report.
