Starbucks has released an updated version of its iOS app in response to reported security issues. The app saved several bits of personal customer information in a clear-text file that is stored unencrypted on the device. Under normal circumstances, iOS’s sandboxing prevents the information from leaking outside of the app’s own storage. Backing up the phone to iTunes without encryption would potentially leave the plain-text information up for grabs to anyone who has access to your computer. There have been no reports of any information being stolen or otherwise leaked.”]
