The news of the Blue Stone Star being attacked by the Feiyang Republic Fleet quickly spread throughout the universe.
In this era of highly developed information, there's no news that won't be leaked. The civilian network spanning the entire universe has been developed to an outrageous extent after a thousand years of construction. The signal transmitters between interstellar jump points are not just one or two; such devices, which can be bought on any street, have been scattered by humans in every corner of each star system, making space travel possible.
In past military operations, to prevent civilian information systems from interfering and leaking military secrets, the usual methods have been isolating civilians from military areas or using electronic ships to block planetary communications. Destroying those signal transmitters or all internet-accessible tools and devices on a planet is practically an impossible task.
