The Guardian has published a Long Read regarding the rise of digital assistants, such as Alexa and Siri, and covered the following emerging privacy and security issues:
Privacy: Privacy protection is considerably weaker after it is transmitted to the cloud and that, in American law, under the fourth amendment, if a person has installed a device that is listening and transmitting to a third party, then they have waived their privacy rights.
Attacks on devices: Researchers have shown that these devices can be hijacked using ultrasonic frequencies from a portable speaker, and can remain undetected by dimming the screen and lowering the volume. A hijacked device could visit a malicious website, place illegitimate calls and messages, and see and hear what is happening around the victim. These attacks present as security concerns, however could also have an impact on investigations, by altering evidence on connected devices, sending phoney messages, or to monitor, stalk and harass victims.
Ethics: There are ethical considerations as to what responsibility a company has to the privacy of their customer versus the moral duty to report to authorities anything concerning their devices capture. Similarly there is an ethical question as to when it becomes a company’s fault if their device fails to intervene to a situation.
