Two hackers accused of stealing the names, phone numbers, and residential registration numbers of 8.7 million mobile users. One of the attackers used to work for a local IT company as a senior programmer, Yonhap news agency reported. He is alleged to have made at least $800,000 by selling the stolen data to telemarketing operators. The illegal accessing of customers` data had apparently gone on for five months before KT caught on. The number of affected people account for nearly a half of about 17 million customers of KT.”]
