This app would be very helpful to all the MI (and all other smartphone brand) users experiencing.
Right-click on your device in the list of devices. The App boasts of a very minimalist material design. Right-click the Volume mixer, represented by a speaker icon in the system tray. If you don't hear sound from your device, continue with the next steps. To hear sound from your device, you may need to set them as the default speakers. 
A green tick will appear next to the Bluetooth connection established message after a connection is made. Double-click on your device model name that appears in the device list. After the computer detects your device, it will then automatically proceed to install the driver after which the device will be added to the computer's list of devices. Allow approximately 20 seconds for the computer to detect your device. Press the button for seven seconds if the computer is the second Bluetooth device you're pairing to your device. Press the button for two seconds if the computer is the first Bluetooth device you're pairing to your device. Press the POWER button to enter into pairing mode. Sure, the chips can be redesigned, and in ten years or so, when the last of the old gear is out of service for good, the problem will disappear, but that’s forever in computer time.Īt any rate, the researchers named their proof of concept code “Speake(a)r,” and published their findings in a paper called “Speake(a)r: Turn Speakers to Microphones for Fun and Profit.” It’s a disturbing read, but highly recommended if you want to stay on top of the latest threats to your firm’s security. It would require a complete redesign of RealTek’s chipset, and then a global recall that would impact just about every computer in use today, since almost all of them utilize RealTek hardware. Worst of all, there’s no real way to fix this issue. True, the sound quality the hackers get is lower if the speakers aren’t plugged in, but they can still hear everything you say from a distance of about twenty feet. What that means is that the malware can turn your earbuds or PC speakers into recording devices, but it gets worse.īecause the code actually converts sound into electromagnetic signals that can travel through the air, your speakers and/or earbuds don’t actually even have to be plugged into the system to work. The code borrows audio maker RealTek’s chipset functionality, which allows the code to retask the computer’s output channel as an input channel, without informing the user. 
The particulars of their code sound like something out of a blockbuster Sci Fi movie script, but it’s all too real, and what’s worse is that it impacts just about every computer in use today. A group of Israeli security researchers operating out of Ben Gurion University have created a proof-of-concept app (malware) that can weaponize your computer’s speakers, turning them against you.
