Hackers can steal #cryptographickeys by video-recording power LEDs 60 feet away
Key-leaking #sidechannels are a fact of life. Now they can be done by video-recording power LEDs.
The attacks enable a new way to #exploit two previously disclosed side channels, a class of attack that measures physical effects that leak from a device as it performs a cryptographic operation. By carefully monitoring characteristics such as power consumption, sound, or electromagnetic emissions
