Abstract
Since the generation of Bitcoin, it has gained attention of all sectors of the society. Law breakers committed crimes by utilizing the anonymous characteristics of Bitcoin. Recently, how to track malicious Bitcoin transactions has been proposed and studied. To address the challenge, existing solutions have limitations in accuracy, comprehensiveness, and efficiency. In this paper, we study Bitcoin blackmail virus WannaCry event incurred in May 2017. The three Bitcoin addresses disclosed in this blackmail event are only restricted to receivers accepting Bitcoin sent by victims, and no further transaction has been found yet. Therefore, we acquire and verify experimental data by example of similar Bitcoin blackmail virus CryptoLocker occurred in 2013. We focus on how to track malicious Bitcoin transactions, and adopt a new heuristic clustering method to acquire incidence relation between addresses of Bitcoin and improved Louvain clustering algorithm to further acquire incidence relation between users. In addition, through a lot of experiments, we compare the performance of our algorithm with another related work. The new heuristic clustering method can improve comprehensiveness and accuracy of the results. The improved Louvain clustering algorithm can increase working efficiency. Specifically, we propose a method acquiring internal relationship between Bitcoin addresses and users, so as to make Bitcoin transaction deanonymisation possible, and realize a better utilization of Bitcoin in the future.
