researchers have demonstrated that security cameras infected

with malware can receive covert signals and leak sensitive

information from the very same surveillance devices used to

protect facilities.

To transmit sensitive information, the attacker uses the

camera’s infrared light-emitting LEDs, which are typically used

for night vision. The researchers showed how malware can

control the intensity of the infrared to communicate with a

remote attacker that can receive signals with a simple camera

without detection. Then the attacker can record and decode

these signals to leak sensitive information.
