Personal data of 800,000 Samsung Card leaked

Samsung Card Co., South Korea\'s leading card firm, is suspected of having come under an online security breach that could have leaked about 800,000 customers\' personal data, sources said Thursday. Samsung Card has asked the police to investigate an employee regarding the suspected leakage of customer data, including their names and mobile phone numbers. Sources said Samsung Card submitted to the police a document in which an employee of the card firm confessed that about 800,000 customers\' data might have been leaked. \"But for now, the exact extent of the damage is unknown,\" said an official at Samsung Card. The investigation comes on the heels of a series of online security breach cases, compromising South Korea\'s image as the world\'s most wired country. Concerns about online security breaches have heightened due to a spat of hacking attacks on local financial firms and a popular Internet portal. Hackers struck the consumer finance firm Hyundai Capital Services Inc. and the National Agricultural Cooperative Federation, or Nonghyup, early this year, stealing customers\' personal data and crippling online transactions.
