While demonstrating how to use social media data for intelligence activities, a computer scientist noticed something strange about the data he captured. When this strange data disappeared, he realised that something, or someone, had compromised his computer. Before long, he realised that this wasn't something as mundane as a computer virus. His journey takes him into the murky worlds of the intelligence community and big business. As people around him start to die, he becomes ever-more intent on finding out who is behind the greatest threat to personal liberty and modern civilisation. Based on real technologies, this book also shows how the intellegence community can gather information, use sex and social media as a weapon, and compromise virtually any computer system globally. If you thought you had privacy, think again.
