We all hate it when someone tries to take our information and use it for whatever purpose they see fit. Hackers have developed ways of stealing information through emails, lurking, user accounts, and now… fans? You read that last sentence right. Fans. Some researchers in Israel have been tinkering around in ways to get information through air-gapped computers. Hackers love em’. What’s an air-gap? It’s quite literally:
“A network security measure, also known as air gapping, employed on one or more computers to ensure that a secure computer network is physically isolated from unsecured networks, such as the public Internet or an unsecured local area network” – (Thanks Google.com).
Weird huh? You’d think that something like that would be safe. Not completely it seems. The process isn’t with just any fan near you though. Put the fan next to you down and relax. The hacking method is to take data from your computer by reading the sound emitted by its cooling fan. The technique is interesting but, can only steal a limited amount of data. Unfortunately, that data includes usernames, passwords, and even encryption keys. YIKES. But, don’t fret. They can only steal your information from about 24 feet away. You should be fine keeping your distance from every human within that proximity, right?
