Like a John le Carré novel updated for the digital age, Chasing Shadows provides a gripping account of how the Citizen Lab, the world’s foremost digital watchdogs, uncovered dozens of cyber espionage cases in countries around the world.

In this real-life spy thriller, cyber security expert 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.

From the gritty streets of Guatemala City to the corridors of power in the White House, this compelling narrative traces the journey of the Citizen Lab as it evolved into a globally renowned source of counterintelligence for civil society. As this small team of investigators disarmed cyber mercenaries and helped to improve the digital security of billions of people worldwide, their success brought them, too, into the same sinister crosshairs that plagued the victims they worked to protect.

Deibert recounts how the Lab exposed the world’s pre-eminent cyber-mercenary firm, Israel-based NSO Group—the creators of the phone-hacking marvel Pegasus—in a series of human rights abuses, from domestic spying scandals in Spain, Poland, Hungary, and Greece to its implication in the murder of Washington Post journalist Jamal Khashoggi in 2018.
