An alleged computer hacker is under arrest and facing charges of stealing business information from his employer and selling it to rival companies for 100,000 yuan (HK$93,500). The employee worked for a Taiwanese businessman who runs a large warehouse chain in Guangzhou. He is the first person to be detained for an offence punishable under the criminal code signed into law by President Jiang Zemin last October. The theft caused the company to lose 10 million yuan a month in sales. Li Jianxin, 28, a computer expert from Hunan province, was hired by the warehouse chain. His performance was so good that in nine months he was promoted three times and his salary doubled. But Li allegedly stole business information and copied the computer software used by the Good and More warehouse group. He also reportedly sold the information to other big companies in Guangzhou for 100,000 yuan. Li was arrested when public security officers contacted the firm after the company discovered the crime. The company was unaware that Li had broken the law and fired him but wanted to recover the money he made from selling the information. The members-only warehouse chain boasts 190,000 customers. The company stored information, including contracts, commodity prices and capital details, on its computer system. In September last year, the company began to suspect somebody had been leaking information. A trap was set and Li was caught. He will be put on trial soon. The company has since stepped up its security relating to computer information.
