Abstract

Cryptocurrency investigations have centered almost entirely around the transfer of value “money” or a cryptocurrency asset. The use of cryptocurrency for illicit purposes, especially Bitcoin, is well documented both in academic writing, media reporting and even film documentaries. The infamous SilkRoad market place in addition to the millions of dollars spent within dark markets on drugs, guns and assassinations have grabbed the headlines. This paper looks at how blockchain is creating new areas of investigation that are yet to be explored in detail. This scenario-based research examines the hosting of stolen data (P.I.I) personal identifiable information on a distributed blockchain host where the data is also accessible. The platform used is based on Ethereum infrastructure but demonstrates just one available platform that poses the paradigm. The paper examines the considerations through the lens of an incident responder /cyber investigator, forensics examiner and data controller. The scenario highlights distinct differences in considerations from a traditional response compared to dealing with the immutable and unstoppable distributed technology. The paper concludes that more is needed to be done to understand digital forensics in the blockchain era and the need to develop beyond track and trace in the cryptocurrency investigative tool box. The discussion also brings forth how data retention and GDPR requires consideration when applying it blockchain systems.

区块链调查——超越“金钱”
加密货币调查几乎完全围绕价值“货币”或加密货币资产的转移展开。将加密货币用于非法目的,尤其是比特币,在学术写作、媒体报道甚至电影纪录片中都有很好的记录。臭名昭著的丝绸之路市场,以及黑市上数百万美元的毒品、枪支和暗杀活动,都占据了各大媒体的头条。本文着眼于区块链如何创造尚未详细探索的新调查领域。这种基于场景的研究检查了在分布式区块链主机上托管被盗数据(P.I.I)个人身份信息,其中数据也可以访问。所使用的平台是基于以太坊基础设施的,但只展示了一个可用的平台。本文通过事件响应者/网络调查员、法医审查员和数据控制者的视角考察了这些考虑因素。与处理不可变和不可阻挡的分布式技术相比,该场景突出了传统响应在考虑方面的明显差异。该论文的结论是,需要做更多的工作来了解区块链时代的数字取证,以及在加密货币调查工具箱中开发超越跟踪和追踪的需求。讨论还提出了在应用区块链系统时如何考虑数据保留和GDPR。
