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—from drug manufacturers to software developers to shipping companies. At the attack's epicenter in Ukraine, ATMs froze. The railway and postal systems shut down. Hospitals went dark.

Kevin Mitnick was the most elusive computer break-in artist in history. He accessed computers and networks at the world’s biggest companies—and however fast the authorities were, Mitnick was faster, sprinting through phone switches, computer systems, and cellular networks. He spent years skipping through cyberspace, always three steps ahead and labeled unstoppable.

Zero day: a software bug that allows a hacker to break into your devices and move around undetected. One of the most coveted tools in a spy's arsenal, a zero day has the power to silently spy on your iPhone, dismantle the safety controls at a chemical plant, alter an election and shut down the electric grid (just ask Ukraine). For decades, under cover of classification levels and non-disclosure agreements, the United States government became the world’s dominant hoarder of zero days.

Cult of the Dead Cow is the tale of the oldest, most respected, and most famous American hacking group of all time. Though until now it has remained mostly anonymous, its members invented the concept of hacktivism. Today, the group and its followers are battling electoral misinformation, making personal data safer, and battling to keep technology a force for good instead of for surveillance and oppression. Cult of the Dead Cow shows how governments, corporations, and criminals came to hold immense power over individuals and how we can fight back against them.

In 2011, a 26-year-old libertarian programmer named Ross Ulbricht launched the ultimate free market: the Silk Road, a clandestine website hosted on the Dark Web where anyone could trade anything - drugs, hacking software, forged passports, counterfeit cash, poisons - free of the government's watchful eye. It wasn't long before the media got wind of the new website where anyone - not just teenagers and weed dealers but terrorists and black hat hackers - could buy and sell contraband detection-free.
