Apple's deal with UnionPay extends its lead over rival Google, whose Google Play store for Android apps is blocked in China. That has resulted in scores of third-party stores selling apps, in many cases pirated versions, to consumers there, a practice that has repeatedly spread malware-infected Android apps.
Recently, malware was also spotted being spread by an unauthorized Chinese app store that distributed Mac software, which resulted in Mac infections; those Macs were then used as launching pads to spread spyware-like code to iPhones and iPads in the People's Republic of China (PRC).
On Friday, authorities there arrested three for developing the "Wirelurker" malware used to infect Macs and iOS devices.
