A PLAYBOOK FOR FOLLOWING THE DIGITAL MONEY TRAIL AND SOLVING CRIMES INVOLVING CRYPTO
From high profile cases and media reporting, we know that crimes involving cryptocurrency are on the rise--to the tune of tens of billions of dollars per year. So is this a new type of crime? There's No Such Thing as Crypto Crime: An Investigative Handbook will show you that fraud or theft involving cryptocurrency is substantially the same as fraud or theft of any other financial asset. That's good news for investigators--it means we already have the tools and tactics we need to solve these crimes and stop crypto criminals in their tracks. This book shows you how to apply the principles of financial forensic investigation to the world of digital currency.
Inside, leading cybersecurity and forensics consultant Nick Furneaux, assisted by some of the worlds experts in crypto oriented crime, lays it all out: the technology behind cryptocurrency, the most common types of crime and exploitation, various investigative strategies, and methods for seizing illicitly held assets. From the primary cryptocurrencies of Bitcoin and Ethereum to key alt coins such as Tron and Binance Smart Chain, you'll learn how to follow the trail of blockchain transactions and combat crypto related financial crime.
This is a book that should be read by everyone involved in financially motivated crimes including criminal and tax investigators, lawyers, legislators and more.
