Hi All
Well we have known for a long time, that is potentially possible to hijack a satellite, now more evidence indicates it occurs more often than one thinks.

A fascinating insight.
The security community on the whole is getting involved, as well. On June 6, the US Air Force and Space Force partnered with nonprofit government contractor Aerospace for "Hack-a-Sat," a 30-hour capture-the-flag-style satellite hacking competition centered around "Moonlighter," a hacker sandbox in orbit. Elsewhere, developers have tested a quantum computing-resistant channel for transmitting data to and from a spacecraft.
