However, it may not be with something any hacker would use regularly. They have been taking laser pointers and, occasionally, flashlights to the microphones on smart home devices reports The New York Times. The researchers found that the microphones on these kinds of devices respond to flashing lights the same way a person would to talking to it. Using a laser pointer, these researchers were able to turn the lights on and off again, open smart-locked doors, and even start cars that were linked to smart home devices.
The researchers tested their hypothesis in a variety of situations. One of them, taking place at the University of Michigan, had a Google Home device being hacked from the top of a water tower. Another experiment included using a telephoto lens, where the researchers were able to override a device feet away.
Kevin Fu, Associate Professor of Electrical Engineering and Computer Science at the University of Michigan, is surprised how much can be affected by a simple laser pointer.
There is a wide gap between what computers are supposed to do and what they actually do. I would love to put together a dance party that uses biological visuals. Last year we saw a laser-based microscope that shined the beam of light through a water droplet […].
If you insist on being an idiot, then do so alone. Imagine the poor schools biology class potential.. Not to mention easy first-look check if water found in oasis is good to drink. Why this stuff is not in survival kits? I managed to see some water fleas with just a laser and a syringe full of pond water. Is it just simple optics? I want to measure if the wavelenght of the laser or the material is important.

As a community platform hackteria tries to encourage the collaboration of scientists, hackers and artists to combine their experitise, write critical and theoretical reflections, share simple instructions to work with lifescience technologies and cooperate on the organization of workshops, temporary labs, hack-sprints and meetings. Hackteria operates on a global scale, and is based on a web platform and a wiki for sharing knowledge, which enable anyone to learn but also test different ways of hacking living systems.
