The session starts with an outline of current methods for blockchain and traffic analysis. Next, the speakers explain in detail the properties of cryptocurrencies, including address clustering, coin-joining of inputs, transaction mixing, and traffic correlation. It then focuses on employing previously described methods to obtain intel about dark marketplace operators, vendors, and buyers. To address cryptocurrency forensics, we have developed a set of tools (exclusively available to law enforcement agencies) that are capable of correlating things happening in real life with the blockchain. Moreover, participants will have a chance to bring their cryptocurrency addresses/transactions for assessment. In the end, the presentation discusses state-of-the-art options to overcome wallet cryptography and briefly mentions current hardware and software solutions for password cracking.
