“Small satellites that have propulsion systems, but don’t have encrypted commanding systems, pose a small — but. real threat of being hacked and endangering other satellites,” according to a new report by a team of researchers from Stanford, Yale, and the University of Colorado. Jeff Foust, in an August 9, 2018 article he posted on SpaceNews.com, provided details of the recently completed study. Mr. Foust wrote that “the research by a team of graduate students, presented at the AIAA/Utah State University Conference on Small Satellites held on August 9, “recommended the space industry take steps to prevent the launch of such satellites to avoid an incident to lead to “regulatory over-reaction” by government agencies.” “We would propose a policy that, for those cubesats, and smallsats that have propulsion, the industry adopt a ‘no encryption, no-fly rule,’ said Andrew Kurzrok of Yale University.
