They can even do it from a distance.
Security researchers have revealed that laser pointers are now capable of hacking popular smart speakers. Since it’s a laser pointer, that means it is able to do that even when its a couple of meters away.
An explanation said that the microphones found inside smart speakers translate the sound that it is hearing into electrical signals which is how the device interprets the command. But it was later found out that a focused light (i.e. a laser pointer) is also capable of sending signals to the microphone.
This vulnerability means that someone can potentially take over devices operated by voice, and of course, smart speakers are the first ones you’d think of. The discovery was made through the research efforts of the University of Michigan and the University of Electro-Communications in Tokyo.
Add to the fact that most smart speakers typically respond to any command immediately without the need for any type of authentication. The researchers also revealed how they managed to hack a Google Home from far away using only a cheap laser pointer.
You can argue that these are only smart speakers – but there should be enough data stored in them that could potentially steal your personal information. At the moment, affected companies said that the threat is only limited to a few users.
