An app in the App Store named "Find and Call" was discovered this morning to be malware. The news quickly spread around the blogosphere, and the app was promptly removed by Apple for its unauthorized use of the iPhone's address book. Once installed, the app would surreptitiously upload all of your contact information to a remote server. It would then send a text message to everyone in your address book suggesting they also download the app and giving a link. The message would appear to be from your number, so that the recipients wouldn't suspect anything. There is question now how such an app could have passed muster in the App Store, and it shows that iOS devices aren't immune from malware despite the scrutiny that Apple gives every app that's made available in the App Store.
