  Hyperloop is among the most prominent future transportation systems. It
involves novel technologies to allow traveling at a maximum speed of 1220km/h
while guaranteeing sustainability. Due to the system's performance requirements
and the critical infrastructure it represents, its safety and security must be
carefully considered. In transportation systems, cyberattacks could lead to
safety issues with catastrophic consequences for the population and the
surrounding environment. To this day, no research investigated the
cybersecurity issues of the Hyperloop technology.
  In this paper, we provide the first analysis of the cybersecurity challenges
of the interconnections between the different components of the Hyperloop
ecosystem. We base our analysis on the currently available Hyperloop
implementations, distilling those features that will likely be present in its
final design. Moreover, we investigate possible infrastructure management
approaches and their security concerns. Finally, we discuss countermeasures and
future directions for the security of the Hyperloop design.
