"Jailbroken device" ....
Don't waste our time with crap like this.
A group of computer scientists from Italy and Poland reckon they can use steganography to hide covert messages in users' voice commands to Siri. What's interesting about the work, described in this paper at Arxiv, is that it doesn't involve installing new software on the target device. Rather, iStegSiri would exist as a man-in …
Is that this could be done on anything that uses digitized voice, from telephones to voice commands. They mentioned Siri since "potential security problem in Siri" draws headlines. Though I would have thought "terrorists can use steganography to send hidden messages even on lines tapped by the authorities" might garner them a chunk of research funds. Too bad they aren't smart enough to think of that.
Nevermind that the old fashioned code word method is a lot simpler and has a higher data rate, but I guess they're researching steganography and trying to claim it is some serious issue...
Its getting to the point where I kind of tune out any researchers talking about security issues having to do with Apple, when they later reveal the issue isn't specific to Apple at all. It is like a producer talking about a new movie and suggesting "maybe Tom Cruise will play the lead role" to get publicity even though he's never spoken to him about it.
You could just as well stand behind a person with a phone and use a device to convert your voice to extremely high pitched sounds with the person you are talking to similarly lurking on the other end of the line with a decoder. It would be similarly practical but way more cool. It wouldn't even require a jailbroken phone.
"a typical 16-digit credit card number can be transmitted in about 2 minutes"
(Who) the hell spends over two minutes talking to their phone (be it Siri or the Wife?) ?
And assuming an attacker can add a credit card number into my Siri channel (Why?) - (how) do they get it to Bob ?
What's the point. The researchers will get an award or something and end up earning more than most of us because of it.
Yes Vicar - I would like some more tea too.
