Hana SK Card says SK Telecom customers' data safe

SEOUL, Sept. 20 (Yonhap) -- Hana SK Card Co., a South Korean credit card firm, said Tuesday that SK Telecom Co. customers' data was not included in the personal information leaked by its employee.
The card firm, a joint venture between Hana Financial Group Inc. and SK Telecom, said on Monday that one staff member handed over names, addresses and resident registration numbers of its customers to a local telemarketing company.
"Hana SK Card and SK Telecom do not share their customer information," said an official from Hana SK Card, refuting the employee's claim that he stole the personal data of some 50,000 SK Telecom users.
It said that only clients of its credit card were affected by the security breach.
SK Telecom is South Korea's biggest mobile carrier, taking up about half of the country's wireless market with more than 26 million subscribers. Partly due to the report on the data leakage, shares of SK Telecom fell 2.27 percent to 150,500 won (US$131) on the Seoul bourse on Tuesday.
Hana SK Card said it was tipped off about the data leak and conducted an internal probe to determine who was responsible for the release of the sensitive information. It called police earlier to investigate the employee.
Online data leakages have spurred concern about lax online security for customers' private data at financial firms in South Korea. Another credit card firm, Samsung Card Co., saw a similar data leakage earlier this month, reporting some 800,000 customers were affected.
