Flatbed Scanners Used As Relay Point For Controlling Malware (bleepingcomputer.com)
An anonymous reader writes:
"Scientists from two Israeli universities have come up with a way to use flatbed scanners as relay points when sending commands to malware installed on an air-gapped computer," reports BleepingComputer. "Further research also revealed the scanner could also be used to relay stolen data to a nearby attacker. The technique they came up with revolves around the idea that a beam of light could be interpreted as a binary 1 and the lack of visual stimulant can be considered a binary 0."
The attacks can be carried out with lasers mounted on drones, on fixed stands, or by hacking smart light bulbs present near the targeted computer. Attack distances can go up to 900 meters (0.56 miles). During their tests, researchers sent various commands to the PC, such as "d x.pdf" (delete file x.pdf) and "en q" (encrypt folder q). Relaying such commands took between 50 to 100 milliseconds. This research was done by the same team that created methods to steal data from PCs using a hard drive's LED, fan heat, sounds emanated by a computer's GPU fan, electromagnetic signals given out by the GPU, and electromagnetic signals given out by an USB bus.
Here's a PDF of the report, which is titled "Oops!...I think I scanned a malware."

Slashdot has jumped the shark one last time.
So you have to get malware on to the air-gapped computer, but once you've done that you can control it from hundreds of meters away using a laser, a hacked smart light globe and a flatbed scanner with the lid open. Riiiiiiiiiiiiiiiiiiiiiiiiiiight . . .
First you have to find someone who still has a flatbed scanner.

So, basically every printer on sale at Best Buy or Wal-Mart.
I went looking for "just a printer" and couldn't find one. All they sell are multifunction machines, at least in the inkjet variety.
