According to research, putting in a computer password while on a Zoom call could leave you vulnerable to a cyber-attack since artificial intelligence (AI) is capable of deducing which keys are being pressed by listening in on the sound of the keyboard being used.According to experts, the potential of sound-based cyberattacks has increased as the use of video conferencing applications like Zoom and integrated microphones on smartphones has increased.
Researchers now claim to have developed a system that, using only sound recordings, can determine, with more than 90% accuracy, which keys are being pressed on a laptop keyboard.
An eye-opening experiment was carried out by a group of professionals to demonstrate how serious this issue is. A MacBook Pro 16-inch was the powerful laptop they were using. To record the keyboard’s noises, they positioned a tiny iPhone 13 Mini at a distance of just 17 centimetres from it on a soft cloth. To record the sounds, they also made advantage of the laptop’s built-in recording feature.
All of this recorded information was later utilised to train an AI-powered smart computer programme to recognise the sounds of typing. This AI was tested after training. It was able to identify the keys being pressed with an astounding 95% accuracy from the iPhone recording and 93% accuracy from the laptop recording.Large language models like ChatGPT can predict the final letters of words, therefore passwords with complete words may be more vulnerable, according to scientists.
It was also discovered that the chance of such password theft might be reduced by using randomly generated fake keystrokes to transmit audio.Researchers suggest using biometric passwords, such as fingerprint or face scanning, rather than typing ones, can also help reduce the risk of such cyberattacks.
