Worm: The first digital world war - Mark Bowden

The Conficker worm infected its first computer in November 2008 and within a month had infiltrated 1.5 million machines in 195 countries. Banks, telecommunications companies and critical government networks - including the British Parliament and the French and German military - were infected. No-one had ever seen anything like it.

By January 2009, the worm lay hidden in at least 8 million computers and the network of linked machines that it had created was big enough that an attack might crash the world's online infrastructure. Worm is the gripping story of the group of hackers, researchers, millionaire Internet entrepreneurs and computer security experts who united to defend the Internet from the Conficker virus. It is an unforgettable account of the first digital world war.
