Well, if you can easily see that the contents of the media articles are at best shallow and at worst utter bullshit, you shouldn't be so quick to accept their characterizations of the researchers themselves at face value.  Even some people here are working on implementing and testing how such an attack would work and (presumably) how to respond to it if it did.

The reason this isn't a huge problem (and why it hasn't affected price) isn't that it doesn't exist, but that if anyone did try to do it they'd a) be caught pretty quickly and b) there would be a rapid response.  Part of why there'd be a rapid response is that people are poking at it looking for potential attacks and (one hopes) having countermeasures already in place if they're ever used.
