Hackers Can Infect Your Computer Even If It’s Not Connected To The Internet

One of the go-to strategies for securing a computer network when a machine is infected with malware is to remove that machine from the network. This effectively prevents the malware from spreading to other devices.

The technique is called “air-gapping” — network admins are building a “roadblock” quite literally made out of air to stop malicious computer code from propagating throughout a network. With no cables connecting the affected machine to the rest of the network, malware has no “road” by which to travel.
