Biography

Lucky Onwuzurike, PhD is a cybersecurity consultant manager at EY, where I perform among other responsibilities, security and risk assessments for clients. I obtained a PhD in Information Security (Information Security Group) from the University College London (UCL) where I was supervised by Prof. Emiliano De Cristofaro and Dr. Gianluca Stringhini. While a Doctoral researcher at UCL, I was teaching assistant for two MSc Information Security modules – Computer Security II and Cryptanalysis. My research interests include: Android security, security and privacy issues on online social networks, and network security. In recent times, I have also developed interest in cloud computing and Internet of Things (IoT). Prior to starting my PhD, I obtained an MSc in Information Security at UCL and a BEng in Computer Engineering at the University of Maiduguri, Nigeria.

Aside from consulting and research, I also have experience working as a Web developer and Network Engineer. I am a music lover (erm.. I know my voice is terrible, so I only sing to myself in the bathroom), I follow latest trends in IT and watch football occasionally. I also play football when I have the opportunity and I have a history of scoring fantastic goals Zlatan Ibrahimović would be proud of. 😉

Factors Influencing Users to Use Unsecured Wi-Fi Networks: Evidence in the Wild

Security experts often question why some users take actions that could expose them to security and privacy risks. Using unsecured Wi-Fi networks is one common example. Previous studies examined stated preferences — what people said they have done or think they would do — but that may not truly reflect real-life behavior. This study is the first to examine revealed preferences — what people actually do in naturalistic settings.

MaMaDroid: Detecting Android Malware by Building Markov Chains of Behavioral Models (Extended Version)

We introduce MaMaDroid, a static-analysis based system that abstracts app’s API calls to their class, package, or family, and builds a model from their sequences obtained from the call graph of an app as Markov chains.
