That's a good collection.PantherX wrote:Agree with backups... air gap is good for unless you have a state actor interested in your data and they are ways to bypass it: https://www.zdnet.com/article/academics ... ibrations/Darth_Peter_dualxeon wrote:...so it's more simple to have backup and air gap for important stuff.
State actors most likely already know most of people's sensitive data like all official paperwork and bank account data and all contacts and physical location. Or they can force someone to give information. Or force the individual to give any passwords. They create the laws after all. One would need to be at the outer space to not be under the power of some state actors in some way..
Mostly I don't want some bug in a software to delete / corrupt data. Multiple backups at multiple locations may also defend someone against house fire or similar events.
And it's one thing to demonstrate a vulnerability as an academic paper, and other to apply it. All computers are different, sometimes it's hard to willfully install something and have it functioning.
likely in a gamer PC there are 5-10 fans, (and some connected directly to constant 12V, or a manually controlled front panel fan speed controller)
the audio output is connected to a headphone not a big speaker, if needed, and probably the owner knows to not click on weird links in weird emails / download stuff from untrusted places.
probably when the pc is on, the owner is in the place. When pc is off, and the owner is away, full disk encryption makes it hard to download or install stuff on the pc.
Leaking data on the HDD led, screen brightness or electromagnetic emissions of the hardware... Yes, interesting. People close the curtains in a crowded neighborhood anyway.
And good luck using electromagnetic emissions as a leak at a building block with a lot of microwave ovens, household devices with electric motors -washing machine, fridge, etc, a gazillion wireless devices - phones, wifi, rc toys, ...
and about the FM band: once a decade ago I fooled around with electronics and built a tiny fm transmitter with 1 transistor and one 1.5V battery and connected it to some music player. At this low voltages, even with proper antenna on both sides, the range was like 15 meters. So, unintended radio-wave emissions of devices that are required by FCC to not create radio interference, is probably very-very low range.
