The truth behind hacking? It’s a global business – and journalists are the least of it

‘Hi, this is Mr Pretext from mobile phone activations. Our systems are down and I need you to bring up a customer’s mobile account for me please.’ I must have repeated this lie thousands of times in the past 20 years. It helped me gain access to information — criminal records, social security numbers, phone logs — that I would then hand on to all sorts of clients: journalists, insurers, cuckolded husbands and even policemen. As an American who spent many years in this underground industry, I can tell you that the British phone-hacking scandal has exposed only a tiny part of a vast criminal network.

In the old days, private investigators would peer through letterboxes or ransack the bins of their targets. In the past ten to 15 years, however, technology has multiplied the ways in which people like me can snoop on people like you. Mobile phone records, health records, anything that is held digitally can be accessed.
