Insider steals and sells credit card data of 20m South Koreans

20 January 2014  |  4381 views  |  1 credit card

South Korean prosecutors have indicted an engineer accused of stealing the credit card details of more than 20 million people and selling them to marketing firms.

The engineer allegedly used his position at the Korea Credit Bureau to access databases belonging to KB Kookmin Card, Lotte Card, and NH Nonghyup Card between May 2012 and December 2013.

The crook copied the card numbers and expiry dates of NongHyup and Lotte customers, but not Kookmin, onto a USB stick. E-mail and residential addresses and phone numbers were also taken.

The information was then sold to marketing firms. Officials at these firms have also now been arrested.

South Korea's Financial Supervisory Service says that the chances of fraud are low because PINs and CVCs were not taken in the theft but any losses will be covered by the card firms.

The bosses of all three companies have made public apologies and several executives have tendered their resignations. According to Bloomberg, 27 people from KB Kookmin Card and its parent have offered to quit.

EMV and online payments providers must focus asap on implementing 'unique per transaction PAN tokenization' methods as part of the fight to make the card data stored and spread across merchant and acquirer/processor systems useless for the thieves.

If such dynamic tokens are structured to preserve original PAN BIN/IIN value (for acquirer ro be able to properly route txn) and if they preserve last 4 digits of the original PAN the merchant and acquirer systems will be unaware of such changes and should continue to function properly and only issuer end points (card and issuer host) will be able to map such token to the original PAN

 

Such tokens would be then useless for anything if stollen
