Through social media, they can plant ideas, manipulate public opinion, and influence elections. And there's precious little we can do to stop them. this book documents the dramatic increase in hacking and data mining incidents in recent years. The articles within it explore how these incidents affect world events, such as the United Kingdom's Brexit vote and the 2016 U.S. presidential election. Investigative articles reveal who is behind these incidents, why they happened, and how we can protect our data.
