The researcher added that he's confident he and his colleagues will eventually be able to attack any smart device.

According to the New York Times, researchers in both China and the USA have carried out a series of experiments which ultimately proved that it's possible to communicate silent commands that are undetectable to the human ear to voice assistants like Siri, Alexa and Google Assistant. With nearly all virtual assistants getting more features, its time we address the inherent security loopholes they open up. Apple points out that HomePod can't do things like open doors, while iPhones have to be unlocked to execute certain Siri commands.

Over the past two years, researchers have worked within university labs on hidden commands that only Siri, Alexa, and Google Assistant will pick up, and not humans. Last year, Burger King caused a stir with an online ad that purposely asked: "OK, Google, what is the Whopper burger?" Android devices with voice-enabled search would respond by reading from the Whopper's Wikipedia page. It is also an area where laws have to catch up, as there is very little legislation on sending subliminal messages to humans and no such laws against sending those inaudible commands to other people's machines. For its part, the Federal Communications Commission (FCC) has discouraged the practice, calling it "counter to the public interest". One method called DolphinAttack even muted the target phone before issuing inaudible commands, so the owner wouldn't hear the device's responses. The researchers hid the command - "OK Google, browse to evil.com" in a recording of the spoken phrase, "Without the data set, the article is useless". In addition, researchers at Princeton and China's Zhejiang University have demonstrated what they are calling the "DolphinAttack". This way, they found out the devices can perceive a series of silent commands that we are incapable of detecting.

Guardiola come clean over Man City futures of Aguero and Sterling
Guardiola said: "They are champions". "They are champions, from the first day in the locker room". Aguero, who has scored 199 goals for City, is now sidelined with a knee injury.

Testing against Mozilla's open source DeepSpeech voice recognition implementation, Carlini and Wagner achieved a 100 percent success rate without having to resort to large amounts of distortion, a hallmark of past attempts at creating audio attacks.

'We want to demonstarte that it's possible and then hope that other people will say, OK this is possible, now let's try and fix it, ' Nicholas Carlini, who co-led the study, told the Times. Like using a Cap'n Crunch whistle from a cereal box to trick payphones into giving free calls, this latest attack is simply the evolution of using a system against itself, and it will make digital assistants (like it did with telephones) more secure in the long run.
