A group of Israeli researchers have improved on a way to steal data from air-gapped computers, thought to be safer from attack due to their isolation from the Internet. They’ve figured out how to turn the computer into a cellular transmitter, leaking bits of data that can be picked up by a nearby low-end mobile phone.
While other research has shown it possible to steal data this way, some of those methods required some hardware modifications to the computer. This attack uses ordinary computer hardware to send out the cellular signals. Their research is the first to show it’s possible to steal data using just specialized malware on the computer.Read more
