What should I do if I scanned a fake QR code?

I'm a staff of a software company that aims to develop products related to Apple devices. I can tell you that it is not easy to hack an iOS device. Our engineers have been devoted themselves to this field for many years, but so far nothing useful hack software has been delivered. From this point you're safe. But to be on the safe side, you'd better change the password of some important apps, especially those connect to your bank card.

I was just discussing such on my site, if you visited it could be anything or nothing!
