"PWMned: modulating data over CCFL display backlight EMI by using DDC-CI to change the backlight brightness setting" "TOSLEAKED: uncovered TOSLINK ports considered evil - receiving TOSLINK signals over tens of meters of air"https://twitter.com/marcan42/status/1010453980906844161 …
"InTheMatriX: hacking the EC to turn your laptop keyboard into a longwave broadcast antenna via scan rate modulation" "DeadMouse: upturned laser optical mice illuminators can generate signals receivable over long distances with a telescope equipped with a narrowband filter"
"HDCPlz: webapps can toggle HDCP on and off via DRM plug-ins to change the EMI signature of HDMI" "HamDrive: modifying HDD firmware to transmit radio via the head write data line" "RicHDter: covert channel between adjacent servers by creating and sensing vibration using HDDs"
