Security researchers Adi Sharabani and Yair Amit have disclosed details about a widespread vulnerability in iOS apps. They estimate that at least 10,000 iOS apps in the Apple App Store are vulnerable to the hack. As a result, apps that display news, stock quotes, social media content, or even some online banking details can be manipulated to display fraudulent information and intercept data sent by the end user. It may be a while until developers can get this fix implemented, so connect to those public networks with extreme caution.
