More Customer Data Leak from Banks

The personal information of another 10,000 customers at Citibank Korea and 40,000 at Standard Chartered Korea have been leaked. Citibank staff fear additional crimes since one case of fraud using previously leaked customer information has already come to light.

In December last year, prosecutors in Changwon, South Gyeongsang Province said the personal information of 34,000 clients at Citibank and 104,000 at Standard Chartered were leaked. And in January of this year, prosecutors in Changwon announced the leaks of 104 million pieces of personal information from KB Kookmin, NH Nonghyup and Lotte Card.

They identified the leak of the personal information of 3 million customers but were unable to determine where they came from. The Financial Supervisory Service scrutinized the leaked data and found that 50,000 came from Citibank and Standard Chartered.

Police in Seoul on Thursday said the personal information of several Citibank customers had been used in a phone fraud scam. It was the first confirmed instance of personal information leaked from a commercial bank being used in a crime.

Citibank and Standard Chartered pledged to compensate customers for any damage.
