An app which allows users to pirate apps snuck onto the App Store by changing the UI based on a user’s locale, location, IP, or something akin. Macworld:

A Chinese iOS application recently found on Apple’s official store contained hidden features that allow users to install pirated apps on non-jailbroken devices. Its creators took advantage of a relatively new feature that lets iOS developers obtain free code-signing certificates for limited app deployment and testing.

Coincidentally, Apple have released some news a couple days ago of an upcoming certification renewal:

How will customers be affected by the certificate renewal?
Customers who have purchased and installed iOS apps, tvOS apps, or Safari Extensions will not be affected by the certificate renewal. Users running OS X El Capitan (v10.11 or v10.11.1) may receive a notification that your Mac app is damaged if it utilizes receipt validation to request a new receipt from Apple. They can resolve this issue by restarting their Mac or updating to OS X El Capitan (v10.11.2) or later.

It seem I’m not the only one that finds certification, provisioning, and code signing confusing …

As a side note, I ran into this bug this weekend.
