  Satellite user terminals are a promising target for adversaries seeking to
target satellite communication networks. Despite this, many protections
commonly found in terrestrial routers are not present in some user terminals.
  As a case study we audit the attack surface presented by the Starlink
router's admin interface, using fuzzing to uncover a denial of service attack
on the Starlink user terminal. We explore the attack's impact, particularly in
the cases of drive-by attackers, and attackers that are able to maintain a
continuous presence on the network. Finally, we discuss wider implications,
looking at lessons learned in terrestrial router security, and how to properly
implement them in this new context.
