Sending Silent Commands to Voice Assistants

Researchers have demonstrated the ability to send inaudible commands to voice assistants like Alexa, Siri, and Google Assistant.

Over the last two years, researchers in China and the United States have begun demonstrating that they can send hidden commands that are undetectable to the human ear to Apple's Siri, Amazon's Alexa and Google's Assistant. Inside university labs, the researchers have been able to secretly activate the artificial intelligence systems on smartphones and smart speakers, making them dial phone numbers or open websites. In the wrong hands, the technology could be used to unlock doorswire money or buy stuff online ­-- simply with music playing over the radio.
A group of students from University of California, Berkeley, and Georgetown University showed in 2016 that they could hide commands in white noise played over loudspeakers and through YouTube videos to get smart devices to turn on airplane mode or open a website.

This month, some of those Berkeley researchers published a research paper that went further, saying they could embed commands directly into recordings of music or spoken text. So while a human listener hears someone talking or an orchestra playing, Amazon's Echo speaker might hear an instruction to add something to your shopping list.


Some malicious codes can automatically record your cam and later demand for ransom if you deny they may threaten you with a mail like below.

Hello.


If you were more watchful while caress yourself, I wouldn't write dis message. I don't think that playing with yourself is really bad, but when all colleagues, relatives and friends receive video record of it- it is obviously for you.

I placed malisious soft on a porn site which was visited by you. When the target press on a play button, device starts recording the screen and all cameras on your device starts working.

Moreover, my program makes a remote desktop supplied with keylogger function from your device , so I could get all contacts from ya e-mail, messengers and other social networks. I'm writing on dis e-mail because It's your working address, so u should read it.

I suppose that three hundred usd is pretty enough for this little misstep. I made a split screen video(records from screen (u have interesting tastes ) and camera ooooooh... its funny AF)

So its ur choice, if u want me to erase ur disgrace use my bitcоin wallet аddress- 1wxxxxxxxxxxxxxxxxxxxxxxxxxxxxx  
You have one day after opening my message, I put the special tracking pixel in it, so when you will open it I will see.If ya want me to show u the proofs, reply on this letter and I will send my creation to five contacts that I've got from ur contacts.

P.S.. U can try to complain to police, but I don't think that they can help, the investigation will last for several months- I'm from Estonia - so I dgf lmao
