Israeli researchers compromise isolated network with dumbphones

Without a doubt, storing highly sensitive data on an internet-disconnected, “air-gapped” computer network is one of the best security measures an organization can take — but nothing is full-proof.

All it takes is a little malware and an old, non-smart mobile phone.
