- Martin and Martha are specialists in covert operations. The matter is very urgent, otherwise they wouldn't have brought me specially by coast guard helicopter. The helicopter landed at a distant parking lot. There were no people in the parking lot. I was brought in a car with tinted windows directly from the helicopter. So you wanted no one to see me. Martha was driving, so the circle of initiates is very small. More?

- Enough. Martin, you were right to pay attention to this young man. He knows how to see details!

- So, Bob, we need to gain control over the smart home system. It is controlled by a voice assistant. By hacking this device, we will get full access to all smart devices.

— Is ? Do we know where it is installed? Is there a house within direct line of sight? Can we rent this house?

- And you are a businessman! I can answer all paraguay mobile database questions - yes! We have already rented the house. Will you need equipment? Prepare a list and give it to Marta. She will get everything. What do you need?

— A laser. And some other equipment. I’ll prepare a list. The thing is, not long ago, security researchers discovered a way to hack a voice assistant using a laser beam and take over the user’s account. The experts conducted a study to find out why digital home assistants and other sensory systems that use sound commands to perform functions can be hacked using light.

- Wait, but how? There's a microphone there, right?

— During the study, they found that by modulating the electrical signal with the intensity of the light beam, they could trick microphones into producing electrical signals as if they were receiving real sound.

- Wait, you mean to tell me that you can make this assistant follow your commands?

— Exactly. There is often no user authentication on these devices, allowing voice commands entered via light to be used to unlock front doors protected by a smart lock, open garage doors, make purchases on e-commerce sites at the victim’s expense, or even unlock and start various cars connected to a Google account, such as Tesla and Ford.
