In Battlestar Galactica (2004) robots called Cylons attack the humans by hacking their computer network. They are able to destroy most of humanity and all but a handful of human ships. One of the ships that survives is the Battlestar Galactica, an old ship that was about to become a museum, and is too old to be connected to the network. The man in the picture is Admiral William Adama, captain of the Galactica. He orders that computers are not to be networked together, so they can’t be hacked by the Cylons.
In real life cyber security provider CrowdStrike had a bug in one of its update files. The file went out as part of an automated update to computers at many businesses around the world, including banks and airlines. The bug made the computers crash, grounding flights, making payment systems inoperable, etc.
