That's great! You just further proven my point!

If this article tells us that samsung Knox is more secured than any other platforms and it got hacked, I believe iOS is even worse!
The fact that it was hacked doesn't prove that it is less secured than any other platform. It simply just means IT GOT HACKED. Even the most "secure" system can get hacked. How easy can you get through the system is the question, and Knox is definitely better at security.
If there's a system, there's always a flaw, its just how easy for someone to find it and take advantage of it. learn that and deal with it.
