The researchers at the University of Michigan were able to access any of these products by shooting sonic waves at their vulnerable sensors. They then could use the compromised sensors as a backdoor to the device.
The troubling finding shows that computer engineers and technology companies need to worry about not just the security of software, but hardware as well.
The research will be presented at a symposium next month in Europe.
The study adds to the mounting security concerns revolving around the so-called “Internet of Things”, a term used to encompass the large group of devices and appliances that can connect to the web.
Using a cheap speaker, the researchers could trick a wearable fitness tracker, Fitbit, into adding thousands of steps to its count.
A toy car controlled by a smartphone app could similarly be piloted with a malicious audio file.
The study authors used another audio file to trick the sensors of a Samsung Galaxy S5 smartphone into spelling the word “walnut” in a graph illustrating the sensors’ readings.
Similar to the famous concept of an opera singer breaking a wine glass by hitting a certain note, the researchers found that sensor technology can be manipulated with sound.
“The fundamental physics of the hardware allowed us to trick sensors into delivering a false reality to the microprocessor," lead author Kevin Fu said in a statement. "Our findings upend widely held assumptions about the security of the underlying hardware. If you look through the lens of computer science, you won't see this security problem. If you look through the lens of materials science, you won't see this security problem. Only when looking through both lenses at the same time can one see these vulnerabilities.”
Facebook, which came under criticism for its role in the spread of misinformation during the 2016 US presidential campaign, has argued the platform did not play a major role in influencing voters.
Cassini skimmed closer than any previous spacecraft to the sixth planet from the Sun, and lived to tell the tale, sending back a signal that arrived early Thursday at 0656 GMT, about 20 hours after the crossing took place.
For first time ever, researchers grow working brain circuitry in a lab setting from stem cells
Current virtual assistants have been described as a step into an era of controlling computers by speaking instead of typing or tapping screens.
Saturn has more than 60 moons, and Cassini has made new discoveries on some of them, which may have conditions suitable for a form of life.
Facebook is looking at creating "silent-speech interfaces" based on sensors that could be worn, and made in quantity.
The arbitration court in Moscow approved the deal which lasts for six years and nine months, Russian news agencies said.
The security improvement was described as being part of a broader effort to rid the leading social network of hoaxes, misinformation and fake news by verifying people's identities.
Last year, Musk announced that Tesla plans to build a new pickup truck, an urban bus, and launch a sharing system of self-driving cars.
Plunging the Cassini spacecraft down over Saturn's moon Enceladus , the space agency was able to capture samples of water plumes erupting from the surface.
Enceladus likely contains environments similar to Earth
Facebook chief Mark Zuckerberg has sought to deflect criticism that the huge social network may have been used to fuel the spread of misinformation that affected the 2016 US presidential race.
The inexpensive technique, which can have broad applications in monitoring and protecting aquatic life, was conducted in the East River, which is actually an inlet, and the Hudson River last year.
The skin sensors currently used to monitor vital signs in babies born prematurely generate false alarms in up to 90 percent of cases, mainly set off by the baby's movement.
Social media platform says government summons for user’s identity was withdrawn
Social media company reveals lengthy list of tips to improve its users’ ability to spot hoaxes
