From a tech perspective, insanely clever to use modern phones rolling shutter mode to sample significantly more data points.
From a "is this going to cause problems for the average person" perspective - not even close. Requires 65 minutes of recorded, stable footage. The camera must be < 6 feet away if the lights are on, and the cryptography algorithm must be running during that magic hour of recording...
It does enable remote attacks, but only if all very specific requirements are met, and it requires you have access to a camera for a long period of time that is perfectly positioned.
sounds like a job for a hacked cam ;)
The rolling shutter trick is amazing.
