"There are 8.7 billion devices currently connected to the Internet - and each one is a threat. We think nothing of making an online transaction, using a smartphone or a cash machine, but as we become increasingly dependent on the electronic flow of information, it makes us vulnerable to cyber attack, as hostile nations and high-tech criminal organizations attempt to steal, spy and undermine on a massive scale. [This book] confronts this horrifying reality, exploring the digital dangers we face and examines the extremes they could reach."--Back cover.
