What they don’t know is that ambient light sensors can be used with machine learning methods to extract data like they are weak cameras.

I generally hear from people: “But we have nothing to hide!” Well, you have more to hide than you think, and your data can be combined with other data collected from you elsewhere to produce intelligence at a level you can’t even imagine possible. And those who collect the data are not necessarily those with right intentions. Your data can be collected by different threat actors to be analyzed using AI and be used for different purposes and intentions.

In cybersecurity, we assume that if a type of attack is possible and there is an opportunity to perform an attack, then there might be motive to perform those attacks.

They even developed a fake off mode to show that the TV is off when they collect those conversations. If you think your TV might listen to your conversation, it is better to unplug it when not in use. It also saves you some energy because plugged devices even while not in use may consume some electricity.

Your tablet or laptop light sensor can capture your hand or your image

I always adjust screen light manually, and I believe I have a good reason for that.

The ambient light sensor is used to measure the amount of light and to adjust the brightness of the screen. Ambient light sensors can be used to capture images or keystrokes to steal passwords and data.

Side channel attacks are a type of physical attack that measures changes in device output while a device performs an action. This type of attack is usually more sophisticated and targets certain assets like encryption keys. Duk da haka, if an attack method is developed for certain types of devices, it won’t be very difficult to expand it to other similar devices and even automate it.

Motion sensors (gyroscope) can be used to record your voice

Now that we learned your mouse can be used to record your talking, it’s good to know that motion sensors can also be used for the same purpose. This is important as almost all modern smart devices like phones and tablets have a gyroscope or motion sensor. The sensor acts as a vibrating device, yin shi cikakke don hare-haren hanyar gefe da kuma ɗaukar murya, kamar yadda raƙuman sauti na iya haifar da ƙaramin girgiza.
