“It’s just by the very nature of the operating system itself becoming much more common,” Wood said. “There are a lot more researchers now looking at OS X and finding vulnerabilities and publishing those without actually going to Apple and saying, ‘We found these bugs.’”

“Criminals are not going to shift away from targeting Windows as long as it remains such a widely accessible desktop, but there’s certainly nothing stopping them from looking at other alternatives as well,” Wood said.
