Title: Siri and Alexa can be turned against you by ultrasound whispers
Post by: Bugbatter on September 07, 2017, 05:43:02 PM
Did you hear that? You might not have, but Alexa did. Voice assistants have been successfully hijacked using sounds above the range of human hearing. Once in, hackers were able to make phone calls, post on social media and disconnect wireless services, among other things.

Assistants falling for the ploy included Amazon Alexa, Apple’s Siri, Google Now, Samsung S Voice, Microsoft Cortana and Huawei HiVoice, as well as some voice control systems used in cars.

The hack was created by Guoming Zhang, Chen Yan and their team at Zhejiang University in China. Using ultrasound, an inaudible command can be used to wake the assistant, giving the attacker control of the speaker, smartphone or other device, as well as access to any connected systems.
