A New Zealand teenager allegedly at the center of an international cyber crime network appeared Friday in court where he was charged with computer hacking crimes. Computer programmer Owen Thor Walker, 18, was charged with two counts of accessing a computer for dishonest purpose, damaging or interfering with a computer system, possessing software for committing crime, and two counts of accessing a computer system without authorization. Walker did not enter a plea when he appeared briefly in Thames Magistrate's Court in northern New Zealand. He was released on bail. Bail conditions were not immediately available. Walker was arrested in November last year in the northern city of Hamilton as part of an international investigation into a cyber crime network accused of infiltrating 1.3 million computers and skimming millions of dollars from victims' bank accounts.
