You would be shocked how much "old/abandoned" hardware is in production use all over the world in very sensitive places.

Our exploit chains demonstrate why end-of-life (EOL) hardware poses persistent security risks: when manufacturers stop releasing updates, unpatched vulnerabilities remain frozen in time like fossils, creating perfect targets for attackers.
