In his real-life spy thriller, Chasing Shadows, Ronald Deibert details the unseemly marketplace for high-tech surveillance, professional disinformation, and computerized malfeasance. He reveals how his team of digital sleuths at the Citizen Lab have lifted the lid on dozens of covert operations targeting innocent citizens everywhere. Chasing Shadows provides a front-row seat to a dark underworld of digital espionage, disinformation, and subversion. There, autocrats and dictators peer into their targets’ lives with the mere press of a button, spreading their tentacles of authoritarianism through a digital ecosystem that is insecure, poorly regulated, and prone to abuse. The activists, opposition figures, and journalists who dare to advocate for basic political rights and freedoms are hounded, arrested, tortured, and sometimes murdered.
