Apple Prohibited 250 Apps That Secretly Collected User Information

Apple prohibited 250 apps that secretly collected user information. The iPhone maker made the announcement a day after researchers found hundreds of apps using Chinese advertising software that extracts "personally identifiable user information."

Apple confirmed that discovery Monday.

"We've placed a group of apps that are using a third-party advertising SDK (software development kit), developed by Youmi, a mobile advertising provider, that... gather private information, such as user email addresses and device identifiers, and route data to its company server," the California-based company said in a statement to AFP.

"This is a violation of our security and privacy guidelines. The apps using Youmi's SDK will be removed from the App Store and any new apps submitted to the App Store using this SDK will be eliminated.

"We are running closely with developers to aid them get updated versions of their apps that are safe for customers and in conformity with our guidelines back in the App Store quickly." Apple does not permit third-party applications to share data about a user without obtaining users' permission, and it rejects apps that ask users to share personal data, such as email addresses or birth dates.

Researchers at the mobile analytics firm SourceDNA said Sunday they had seen hundreds of apps that pull up personal information, saying it was "the first time we've seen iOS apps successfully bypass the app review process."

The researchers said they found 256 apps with an estimated one million downloads that accept a version of Youmi that violates user privacy.

"Most of the developers are located in China," the researchers said in a web log spot. "We consider the developers of these apps aren't aware of this since the SDK is delivered in binary form, obfuscated, and user info is uploaded to Youmi's server."
