'A chilling account of a Kremlin-led cyberattack, a new front in global conflict" -Financial Times

The true story of the most devastating act of cyberwarfare in history and the desperate hunt to identify and track the elite Russian agents behind it.

In 2014, the world witnessed the start of a mysterious series of cyberattacks. Targeting American utility companies, NATO, and electric grids in Eastern Europe, the strikes grew ever more brazen. They culminated in the summer of 2017, when the malware known as NotPetya was unleashed, penetrating, disrupting, and paralyzing some of the world's largest businesses. At the attack's epicenter in Ukraine, ATMs froze. The railway and postal systems shut down. Hospitals went dark. NotPetya spread around the world, inflicting an unprecedented ten billion dollars in damage - the largest, most destructive cyberattack the world had ever seen.

This is the true story of the hunt to unmask Sandworm: the group of hackers behind the attacks working in service of Russia's military intelligence agency. Following the years-long, globe-spanning work of the detectives tracking them, Operation Sandworm also exposes the larger story of a new global arms race, and the geopolitical chaos it is unleashing on the world. A narrative full of twists and turns, it captures a chilling new reality: in a war without borders, all of us live on the frontline.
