Researchers in Israel have come up with a couple of unique pieces of malware that can be used to steal data using the magnetic fields generated by a cpu. As a matter of fact they demonstrated this can even work if the cpu is inside of a Faraday cage. These guys have found many ways to get data out of air-gapped networks, but this one has to be the best one yet. Check out the video below to see how the ODINI version works. Watch the video here. Ben Gurion University researchers have developed two pieces of malware that rely on magnetic fields to exfiltrate data from an air-gapped device. One of them is called ODINI and it uses this method to transmit the data to a nearby magnetic sensor. The second piece of malware is named MAGNETO and it sends data to a smartphone, which typically have magnetometers for determining the device’s orientation.
