That's a link nto an article talking about spyware that can be installed when you have WhatsApp installed, your WhatsApp number gets called, and you don't answer.  I haven't seen any technical discussion on how this is possible yet, but holy cripes, that is a wide-open security hole...

I imagine it like sends some kind of graphic or script or /something/ that can be exploited when a call is missed. The phone displays it and wham.  Gifs and pngs have been exploited that way before, in fact i think older versions of android's image loading code is known to have code execution exploits.
