The Threat of  Information Security About Amazon’s Alexa

In the world of the Internet of Things (IoT), researchers discovered that hackers can reprogram Amazon’s Alexa service to control it to eavesdrop on user conversations and transcribe the sensitive information. The hacker only needs to create an application that allows the voice-activated digital assistant to transcribe all the content it heard, and lead the hacker to maliciously exploit the confidential information in the home.

The design concept of the Alexa digital assistant is that it is always in the standby state, the built-in microphone is continuously turned on and monitored until the specific keyword is heard. Then the device enters the interactive mode, and start recording the user’s conversation. However, the researchers found that it can be exploited by inserting the API empty prompt code, which represents that Alexa thinks it has notified the user that the device is still listening, but it is actually silent. As a result, the user does not realize that the smart speaker is still eavesdropping on their conversation.
