The US Department of Defense is working on a classified program called the Tactical Electromagnetic Cyber Warfare Demonstrator program , which aims to give the military the ability to input and output data from network cables without having any physical contact with the cables.
This can be achieved because the electronic data stream emits an electromagnetic signal. In theory, this signal can be intercepted and even altered using radio frequencies.
According to Defense News, the U.S. Department of Defense hopes to be able to “plant” worms into isolated networks from ground vehicles or aircraft. This would give new meaning to the concept of cyber warfare.
On the other hand, this won't be easy. Bogdan Botezatu, Senior Analyst at Bitdefender, says that mission-critical networks typically use coaxial cables, rather than Cat 5 or Cat 6 cables, softpedia reports.
Coaxial cables have very low radiation losses as well as low sensitivity to external interference.
