Hacking Satellite Systems

About a year ago, six academics from Ruhr University Bochum and the CISPA  Helmholtz Center for Information Security set out to survey engineers and developers on the subject of satellite cybersecurity. But most of these engineers were very reluctant to share any details about their satellites and their security aspects. Why were satellite engineers so reticent to talk about cybersecurity? What was so secretive, so wrong with it, that they didn’t feel they could answer even general questions, anonymously? Because let’s be clear: if there’s something wrong with the security of satellites, that’d be a serious problem.
