The US charged three Chinese nationals with hacking two New York law firms and stealing data from their email servers, which they later used to make a profit on the stock market. The three suspects are Iat Hong, aged 26 from Macau; Chin Hung, 50, of Macau, and Bo Zheng, 30, of Changsha, China. Of the three, only Hong is detained and awaiting extradition, after he was arrested in Hong Kong on Christmas Day. The two other suspects remain at large.
