Apple iOS Malware

As detailed here, http://appleinsider.com/articles/15/09/24/apple-lists-top-25-apps-affected-by-xcodeghost-malware-infiltration, a group of iOS apps have been published to the app store with malware.

The concern here is whether causation versus correlation is at play here, as many of these apps were for the Chinese market.

Did the malware exploit a more forgiving vetting process from Apple due to complexities with encoding for Mandarin and / or Cantonese?  Or, is it a more general issue regarding the vetting of apps for the Asian market?

Regardless, Apple products are no longer under the radar for security concerns, and we should act appropriately.
