A New Zealand teenager who helped a crime gang hack into more than 1 million computers worldwide and skim millions of dollars from bank accounts has a new job as a security consultant for a telecom company. Owen Thor Walker has the skills that can help senior executives and customers understand the security threats to their computer networks, TelstraClear spokesperson Chris Mirams told National Radio on Wednesday. Walker pleaded guilty last July — when he was 18 — to a raft of charges connected to his work for an international network.
