This malware steals data using your Internet-less computer’s fans

So you have an air-gapped computer, or unconnected to the Internet, and you think your data is secured just because it’s not accessible online? In most cases that might be true, but that’s not 100% accurate. There are ways to steal information from computers that are not connected to the web, and smart hackers will not stop looking for such tricks. The newest such malware would let attackers steal information from supposedly secure computers with the help of the sound made by its fans and processor.

Researchers from the Ben Gurion University in Israel explained in a new paper that they would be able to retrieve data from an isolated computer that’s not connected to the internet and doesn’t have cameras or audio hardware in such a manner.
