According to the DM, many users think their phone is “listening” to conversations, as evidenced by contextual ads about a product that a person had previously discussed loudly with family or friends. According to NordVPN engineers, this is not paranoia, but very real given the always-on microphones on mobile devices.
This type of digital surveillance reportedly enables the so-called ultrasonic communication between various devices in the home. TVs, laptops, smartphones and other devices transmit information about the user by sending ultrasonic waves to each other.
Many apps request access to the microphone even if they don’t need it to work properly. According to cybersecurity expert Adrianus Warmenhoven, microphone access is a “gold mine” for advertisers, as it allows you to collect vast amounts of information about the owner of the device without his knowledge. The smartphone “eavesdropping” the data transmits it via ultrasound to other devices in the house, so after a phone call on the user’s home computer, only ads that may be of interest appear.
According to Warmenhoven, the transmission of “ultrasonic messages” cannot be stopped for a smart device even if the internet is turned off. The only way to protect it is to completely ban the microphone from being used by third-party apps.
