Cyber Security Series - Laser Bonus

Intro

After doing a Pandemic Series bonus post, I have decided to do the same on this series. Although not enough to make a long post it should make you think.

Laser Spy Devices

Think about it

Many of you make be aware of directional microphones, along with the hijacking of laptop microphones. What many of you may not know about is laser sound capture.

Instead of directional microphones, which can be thwarted with triple glazing and a white noise generator. A laser is pointed at a window and captures the sounds within the room. This is decoded by the receiver that captures the reflected beam.

Such a device has a much greater range than microphones and the technology makes white noise generators less effective. As the decades have passed small lasers can be used and this can include those attached to devices. Xbox kinects are an example of this, although they are more likely to be used to map your 3D environment.

Remember in this age your mobile phone camera can be used to map your environment.
