Suelette Dreyfus and her co-author, WikiLeaks founder Julian Assange, tell the extraordinary true story of the computer underground, and the bizarre lives and crimes of an elite ring of international hackers who took on the establishment.

Spanning three continents and a decade of high level infiltration, they created chaos amongst some of the world's biggest and most powerful organisations, including NASA and the US military. Brilliant and obsessed, many of them found themselves addicted to hacking and phreaking. Some descended into drugs and madness, others ended up in jail.

As riveting as the finest detective novel and meticulously researched, Underground follows the hackers through their crimes, their betrayals, the hunt, raids and investigations. It is a gripping tale of the digital underground.
