Android Market incident that surfaced Wednesday in which Google was forced to pull more than 20 apps that had been Trojaned is the latest piece of evidence that the mobile app store model is broken and is setting users up for failure. The Android Market attack appears to have succeeded to a large degree, as somewhere north of 50,000 Android owners apparently downloaded at least one of the Trojaned apps. Google has responded by removing the most recent batch of malicious apps from the Android Market and has the ability to remotely remove the apps themselves from devices.
