HACK: a Holistic modeling Approach for Cubesat cyberattacKs

Abstract. In recent years, the threat of cyberattacks has been growing rapidly in numerous industrial sectors that have an impact on our daily life. One these is space industry, where risk hacking a single satellite can lead to dangerous effects not only for economics but also Earth critical infrastructure like: transportation systems, water networks, and electric grid. The vulnerability complex systems already demonstrated past. 1998, example, hackers took control ROSAT X-Ray pointing its solar panels directly Sun causing physical damage. Nowadays, since attention moved small less sophisticated system, such as CubeSat, cyber intrusions even higher COTS (Commercial-Off-The-Shelf) technology they use based open-source operating systems. order counteract this imminent problem, development high-fidelity CubeSat digital model needed study solve related cybersecurity issues. fact, thanks virtual prototype, what-if simulations be performed allowing analyze different scenarios predict undesirable events flying operative orbit. Moreover, building requires holistic modeling approach simulation tools which allows consider Multiphysics phenomena occurring system itself. Finally, possibility connecting real obtaining so-called Digital Twin (DT), will help engineers conduct more accurate actions during mission.
