Abstract: In 2020, 53.6 million Amazon Echo Speakers (enabled with Alexa) were sold. This number rose to 65 million in 2021 [1]. Customers can engage with cutting- edge technology in a more natural way by directly dictating instructions to Alexa thanks to its user-friendly, personalised vocal experience. The users' vocal commands are translated into commands by the vendor's cloud services after being transmitted over the internet to the vendor's initial voice assistant devices or companion applications for smartphones and tablets. As this vast amount of data, primarily the user's personal information, moves throughout the voice assistant ecosystem, there are many locations where it is either temporarily or permanently kept. As a result, it is simple for a cyber-attacker to alter this data, raising serious privacy concerns. This, study examines various assaults on the Amazon Alexa ecosystem, including assaults on speech recognition and processing on the cloud backend and frontend audio capturing. We also discuss potential attack surface reduction techniques to make Alexa and other voice assistants more private and secure.
