Tracers in the Dark

"A propulsive story of a new breed of investigators who have cracked the Bitcoin blockchain, taking once-anonymous realms of money, drugs, and violence and holding them up to the light Black markets have always thrived in the shadows of society. Increasingly, these enterprises--drug dealing, money laundering, human trafficking, terrorist funding--have found their shadows online. Digital crime lords inhabiting lawless corners of the internet have operated more freely than their analog counterparts could have ever dreamed of. At the heart of their massive conspiracies: cryptocurrency. By transacting not in dollars or pounds but in Bitcoin--a currency with anonymous ledgers, overseen by no government, beholden to no bankers--black marketeers robbed law enforcement for years of their chief method of cracking down on criminal markets, namely, 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 crack open an entire world of crime. Men with No Names is a story of crime and consequences 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, sex-abuse rings, and the biggest takedown of an online narcotics market in the history of the internet. This is a cat-and-mouse story and a tale of a technological one-upmanship that's utterly of our time. 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?"--
