In Cyber Crime: All That Matters, Peter Warren and Michael Streeter outline the history, scale and importance of cyber crime. In particular they show how cyber crime, cyber espionage and cyber warfare now pose a major threat to society. After analysing the origins of computer crime among early hackers the authors describe how criminal gangs and rogue states have since moved into the online arena with devastating effect at a time when the modern world - including all the communication services and utilities we have come to take for granted - has become utterly dependent on computers and the internet.
