Apple pulls 250 privacy-infringing apps from store

The apps, mostly used by Chinese users, pulled private information from iPhones due to having used a malicious advertising toolkit

Apple has removed 250 apps from its store after discovering a widely-used advertising network was siphoning off private information such as email addresses in breach of the company's policies.

The apps, which are largely from Chinese-based developers, all used a software development kit (SDK) called Youmi to build in advertising. But, apparently unknown to the developers, Youmi also built in code that would steal user data and upload it to Youmi's own servers.
