From the award-winning author of Sandworm comes the propulsive story of a new breed of investigators who have cracked the Bitcoin blockchain, exposing once-anonymous realms of money, drugs, and violence. “I love the book… It reads like a thriller… These stories are amazing.” (Michael Lewis) Over the last decade, a single innovation has massively fueled digital black markets: cryptocurrency. Crime lords inhabiting lawless corners of the internet have operated more freely—whether in drug dealing, money laundering, or human trafficking—than their analog counterparts could have ever dreamed of. By transacting not in dollars or pounds but in currencies with anonymous ledgers, overseen by no government, beholden to no bankers, these black marketeers have sought to rob law enforcement of their chief method of cracking down on illicit finance: following the money. But what if the centerpiece of this dark economy held a secret, fatal flaw? What if their currency wasn’t so cryptic after all? An investigator using the right mixture of technical wizardry, financial forensics, and old-fashioned persistence could uncover an entire world of wrongdoing. Tracers in the Dark is a story of crime and pursuit unlike any other. With unprecedented access to the major players in federal law enforcement and private industry, veteran cybersecurity reporter Andy Greenberg tells an astonishing saga of criminal empires built and destroyed. He introduces an IRS agent with a defiant streak, a Bitcoin-tracing Danish entrepreneur, and a colorful ensemble of hardboiled agents and prosecutors as they delve deep into the crypto-underworld. The result is a thrilling, globe-spanning story of dirty cops, drug bazaars, trafficking rings, and the biggest takedown of an online narcotics market in the history of the Internet. Utterly of our time, Tracers in the Dark is a cat-and-mouse story and a tale of a technological one-upmanship. Filled with canny maneuvering and shocking twists, it answers a provocative question: How would some of the world’s most brazen criminals behave if they were sure they could never get caught?

"With the nuance of a reporter and the pace of a thriller writer, Andy Greenberg gives us a glimpse of the cyberwars of the future while at the same time placing his story in the long arc of Russian and Ukrainian history." —Anne Applebaum, bestselling author of Twilight of Democracy 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: "[A] chilling account of a Kremlin-led cyberattack, a new front in global conflict" (Financial Times). 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. NotPetya spread around the world, inflicting an unprecedented ten billion dollars in damage—the largest, most destructive cyberattack the world had ever seen. The hackers behind these attacks are quickly gaining a reputation as the most dangerous team of cyberwarriors in history: a group known as Sandworm. Working in the service of Russia's military intelligence agency, they represent a persistent, highly skilled force, one whose talents are matched by their willingness to launch broad, unrestrained attacks on the most critical infrastructure of their adversaries. They target government and private sector, military and civilians alike. A chilling, globe-spanning detective story, Sandworm considers the danger this force poses to our national security and stability. As the Kremlin's role in foreign government manipulation comes into greater focus, Sandworm exposes the realities not just of Russia's global digital offensive, but of an era where warfare ceases to be waged on the battlefield. It reveals how the lines between digital and physical conflict, between wartime and peacetime, have begun to blur—with world-shaking implications.

As a white-hat hacker in the Delphi Center’s cyber investigation unit, Laney Knox sneaks into some of the deepest, darkest corners of the Internet looking for predators. Laney would prefer to stay away from Austin PD’s most recent murder case, but she can’t ignore the chilling similarities between that crime and her own brutal attack years ago. Laney offers to help the sexy lead detective, but he wants more from her than just a promising tip—Reed wants her trust. Laney resists, but as their relationship deepens she’s tempted to reveal the closely guarded secrets that could make her a key witness…or the killer’s next victim.
