We demonstrated this in 2016 at PennApps and won the hackathon. The demo video: https://www.youtube.com/watch?v=pAM9c3eBFyECode: https://github.com/fyquah/ramearPress: https://technical.ly/software-development/scary-hardware-hac...The most challenging part was to demonstrate it live on stage, typing on the airgapped desktop and decoding the…

Actually, leaking secrets by air gapped computers is really, really old.I know that e.g. in 1985 the (west) german army had tempest rules e.g. for mobile elint systems. You couldn't use a normal computer for e.g. triangulation, or to look up things in databases. The reason was that even back then video of a normal computers could be monitored from…

Devices like routers should have firmware in memory that has read-only access. The access should be turned on or off by a physical switch.This way, if malware gets installed on your router, doing a cold boot will eliminate it. You can have a timer to just cold boot it regularly.I've suggested this many times. The rationale for not doing it is so…

These and other methods are good reason to believe that AI can never be 100% contained, which gives me pause.The famous air gap case is stuxnet, but there are other technical and biological approaches.It’s a very weird reality we’ve found ourselves in if you stop, zoom out about, and really take in the gravity of the issues we are grappling with…

I used the same approach to play music from a .wav via pulse density modulation -*

There are tons of ways to make air gappped systems transmit data. They all include the installation of some malware and have become more expensive and less usable over time.Back in the day with crt screens you could just capture the frequencies transmitted when creating the picture and look at the copy straight away.No malware. No direct contact…

Does any information leak along the power line? I remember having some device back in the day that let me create a LAN through my apartment's electric wiring.I'm wondering if anything ends up back there thru the PSU during normal use of a computer, or if the high frequency components get filtered out.(Though maybe secure computers do things…

Cool paper even if the attack isn't practical, requiring getting the malware on the computer and a SDR antenna within 7 meters with clear line of sight of the affected computer for 100 bits per second (less after applying error correction). Hard to imagine a scenario where you can pull off both of those, but you couldn't plug in a USB, grab the…

Let me guess, a paper written by Mordechai Guri?It's not even a contest anymore, that man is the heavyweight champ of air-gap security.

I've started to play a meta game when I see new paper on side channels: I try to guess if it's Guri or Elovici this time.
