I tend to think this is an impossible hack, or at least the article is grossly exaggerating things. From the sound of it, they somehow managed to get directly into the wifi and bluetooth chipsets, hijacked them to use [something?] to magically transfer data while they are disabled somehow below the TCP/IP level, within a sandbox...

I mean, assuming they actually did manage this, it wouldn't be portable either. It sounds like they'd have to implement their own driver, which would mean hardware dependence.. and then theirs the fact that they are apparently breaking out of the sandbox and getting direct hardware access, a major exploit..

I call BS

edit: Note, I know that wifi is capable of P2P/ad-hoc connections, and it's what bluetooth uses exclusively... The article seems to say that this app doesn't use that though and has these things disabled
