The boy had two great influences. The first was his grandfather Ronald Lyman, who his family claims received the first degree awarded by the Marconi School of Wireless in Australia, and who served in the army as a signals officer. They also say he later became a spy with the Australian security services. Craig’s favourite place was his grandfather’s basement, a paradise of early computing. ‘We’d sit there and look at these books of log tables,’ he told me. ‘I loved doing it.’ Captain Lyman had an old terminal and a Hayes 80-103A modem that they used to connect to the University of Melbourne’s network. To keep Craig quiet while he worked, Pop, as the children called him, would let him write code. ‘I found this community of hackers,’ Wright says, ‘and I worked out how to interact with them. I started building games and hacking other people’s games. In time, I’d be pulling apart hacker code, and eventually I did this for companies, to help them create defences against hackers.’
