A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

Reminds me of LEDs used to extract data out of airgapped networks: https://threatpost.com/blinking-router-leds-leak-data-from-air-gapped-networks/126199/ but different because that one requires software within the airgapped network to exfiltrate.
Didn't there used to be network equipment that was vulnerable to data exfil from data status lights, or did I dream that up? Most data LEDs now just consistently blink.
