SEOUL/INCHEON, March 6 (Yonhap) -- Personal information of some 12 million customers of KT Corp. was found to have been leaked after the mobile carrier's website was compromised by hackers, local police said Thursday. The number of victims accounts for nearly three-fourths of KT's 16 million clients. Three people, including a telemarketer, were arrested in connection with the case, the Incheon Metropolitan Police Agency said. The leaked information included victims' names, resident registration numbers, places of employment and bank account details. Police believe the suspects began stealing the data last February, with up to 300,000 pieces of information being stolen in a single day. They reportedly made 11.5 billion won (US$10.8 million) by using the information to sell mobile phones. A duo of hackers identified only by their surnames Kim and Jung, ages 29 and 38, allegedly broke into the computer system of the telecom firm by logging onto its Web page using a program of their own creation that allowed them to extract information by randomly inserting nine-digit verification numbers, police said. KT said in an official statement it will make efforts to minimize possible damages to customers, adding that the company will cooperate with the police to uncover the details of the incident.
In January, South Korea's Financial Services Commission revealed that some 20 million clients' personal data, including bank account numbers, addresses and credit ratings, had been leaked from three credit card firms -- KB Kookmin, NH Nonghyup and Lotte.Following the data leak, local financial regulators have been working to revise bills to beef up the protection of personal information.
