This study introduces a direct and intuitive method to resist certain apps from sending SMS message stealthily. According to the heuristic analysis and observation, it is apparently that a SMS message, which has the textual content originated from user's entering manually, is obviously benign. We use this principle to design a serious of SMS examination and verification procedures, in order to force all SMS messages to be verified automatically before delivering them actually. A package named as Taurus, which is comprised of several new components, are developed in the Android framework in this study. The evaluation shows that Taurus, which examines all outgoing and detects potentially malicious SMS messages, has an excellent performance with reasonable memory usage overhead.
