alt Hacker NewsWho says there wasn't?
A lot of the most valuable SpaceX IP (at least to the big "advanced persistent threat" hackers) is probably related to military secrets, information to let you spy on/disable/control star shield/link, and so on. Not things we'd find out about as the general public.
It's highly probable that Russia's top state-controlled hackers have been attempting to exploit/infiltrate SpaceX and Starlink for the past four years.
China has probably being doing so for a decade.
