That same article has a quote from Microsoft: > Google Project Zero was very specific in its blog post that the recently publicized attacks used unique iPhone exploits and they have not disclosed similar information to us," I would be rather surprised if Project Zero ran across new Windows exploits and did not notify Microsoft so I suspect that any exploits they found for Windows used known vulnerabilities.
