A Deep-Dive Into Cryptojacking Malware: From An Empirical Analysis To A Detection Method For Computationally Weak Devices, Ege Tekiner
FIU Electronic Theses and Dissertations
Cryptojacking is an act of using a victim's computation power without his/her consent. Unauthorized mining costs extra electricity consumption and decreases the victim host's computational efficiency dramatically. In this thesis, we perform an extensive research on cryptojacking malware from every aspects. First, we present a systematic overview of cryptojacking malware based on the information obtained from the combination of academic research papers, two large cryptojacking datasets of samples, and numerous major attack instances. Second, we created a dataset of 6269 websites containing cryptomining scripts in their source codes to characterize the in-browser cryptomining ecosystem by differentiating permissioned and permissionless cryptomining …

Privacy-Aware Security Applications In The Era Of Internet Of Things, Abbas Acar
FIU Electronic Theses and Dissertations
In this dissertation, we introduce several novel privacy-aware security applications. We split these contributions into three main categories: First, to strengthen the current authentication mechanisms, we designed two novel privacy-aware alternative complementary authentication mechanisms, Continuous Authentication (CA) and Multi-factor Authentication (MFA). Our first system is Wearable-assisted Continuous Authentication (WACA), where we used the sensor data collected from a wrist-worn device to authenticate users continuously. Then, we improved WACA by integrating a noise-tolerant template matching technique called NTT-Sec to make it privacy-aware as the collected data can be sensitive. We also designed a novel, lightweight, Privacy-aware Continuous Authentication (PACA) protocol. PACA …
