The idea of proxy conflict dates to the Cold War and earlier, but Tim Maurer’s new book “Cyber Mercenaries: The State, Hackers, and Power” makes one of the first forays into proxy conflict in cyberspace. Last week, Maurer sat down with Lawfare Editor-in-Chief Benjamin Wittes at the Hoover Book Soiree to talk about the book. They discussed Maurer’s typology of how states like the United States, Syria, Russia and China differ in their use of cyber proxies and the challenges they pose to attribution and accountability.
