Or what about covering the LED(s) with something so that the camera filming the top secret computer non-stop doesn't have a chance to exploit the side channel?
(excuse the sarcasm; but they were such low-hanging fruits I couldn't resist. The awareness is indeed important, as there are countless other side channels such as USB-cabled mice and keyboards with LEDs...
Also: I'm writing this from a hotel room with a TV illuminating the darkness with its bright standby blue melatonin killer LED - about to hang a towel over it)
- bee_rider 3y agoI put a little dab of red wax on most of my LEDs, not enough to block completely, but just enough to turn it sunset color.
- disillusioned 3y agoThere are a number of LED tape options on Amazon, etc., that offer both extreme dimming and full blackout and they are game-changers for mitigating or removing the scourge of insanely bright blue LEDs in a dark bedroom.
- pmoriarty 3y agoI've used several layers of ordinary blue painter's tape with success for this purpose.

- bee_rider 3y agoExactly!
- ComputerGuru 3y agoActually USB mice and keyboards would not be susceptible here - they use their own power filtering circuits as part of the USB circuitry.

- Version467 3y agoIs the pencil just to save space versus a normal roll of electrical tape, or for some other reason?
- alias_neo 3y agoYou can write with it.
- Hnrobert42 3y agoTo save space. I don’t need a full roll of tape, so I spooled put a few feet and wrapped around a pencil.
