Along with the Strava secret base location leak, another interesting one was the ship with a contraband Starlink:

  As the Independence class Littoral Combat Ship USS Manchester plied the 
  waters of the West Pacific in 2023, it had a totally unauthorized Starlink 
  satellite internet antenna secretly installed on top of the ship by its gold 
  crew’s chiefs. That antenna and associated WiFi network were set up without 
  the knowledge of the ship’s captain, according to a fantastic Navy Times 
  story about this absolutely bizarre scheme. It presented such a huge security 
  risk, violating the basic tenets of operational security and cyber hygiene, 
  that it is hard to believe.
