Abstract
Because of its pseudo-anonimity and decentralisation characteristics, bitcoin payments are often a tool utilised by ransomware: this kind of malware infects a victim computer by encrypting some/all its data and/or denying the access to it. Then, the victim has to pay a given amount of bitcoins to see all the blocked functionalities restored. The goal of this paper is to visualise these bitcoin transactions, and in particular we focus on the effects of one of such ransomware, i.e., WannaCry, one/two weeks after its diffusion. We exploit Block Chain Vis, a tool for visualising flows of bitcoins through the use of Visual Analytics.File in questo prodotto:
