Vasilios Mavroudis is a doctoral researcher in the Information Security Group at University College London. He studies security and privacy aspects of digital ecosystems, with a focus on emerging technologies and previously unknown attack vectors. His recent publication on ultrasound tracking received wide-spread attention and is considered the seminal work on the security of that ecosystem. Vasilios is currently working towards the standardization of ultrasound communications, and designs extensions of his previous attacks. Moreover, in cooperation with industrial partners, he has recently prototyped a high-assurance hardware architecture, that maintains its security properties even in the presence of malicious hardware components. In the past, he has developed auditing tools for the Public Key Infrastructure of Deutsche Bank and participated in an international consortium studying large-scale security threats in telecommunication networks. Furthermore, he has cooperated with UC Santa Barbara in several projects, including a detection system for evasive web-malware. Vasilios holds an Information Security MSc from UCL, and a BSc on Computer Science from University of Macedonia, Greece.
