In this paper, we introduce a defensive cybersecurity framework called Cybergrenade automating various penetration testing tools to sequentially exploit machines connected to a single local network, all underneath a single application running on a Single-Board Computer (SBC). This takes advantage of the SBC's unique capabilities in a way that manual exploitation simply cannot match. Currently, while...
Voice chat and conferencing services may be assumed to be private and secure because of strong encryption algorithms applied to the video stream. We show that information leakage is occurring in video over IP traffic, including for encrypted payloads. It is possible to detect motion and scene changes, such as a person standing up or walking past a camera streaming live video. We accomplish this through...
This paper describes a competition-style of exercise to teach system and network security and to reinforce themes taught in class. The exercise, called NetSecLab, is conducted on a closed network with student-formed teams, each with their own Linux system to defend and from which to launch attacks. Students are expected to learn how to: 1) install the specified Linux distribution; 2) set up the required...
