Chasing Shadows: Cyber Espionage, Subversion, and the Global Fight for Democracy (2025)
Chasing Shadows provides a front-row seat to a dark underworld of digital espionage, dark PR, 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.

Parchment, Printing, and Hypermedia: Communication and World Order Transformation (1997)
Interweaving media theory and historical analysis, this book explores the effect new digital-telecommunication technologies, which Deibert calls hypermedia, will have on the distribution of political power in the next century. Deibert tracks the transformation of Europe from the medieval to the modern and then turns to the hypermedia age, where new digital technologies such as the Internet, encryption, and high-resolution satellite imaging favor nonterritorial institutions and communities, shifting political authority and policymaking from individual nations to transnational corporations, global financial markets, and nongovernmental organizations and activists.
