It is no exaggeration to say that mobile devices have already become an essential tool in our daily life. Among these mobile devices, a representative smart phone is overheating the market by introducing new functions and services whenever a new product is released. However, most users do not know that there are various vulnerabilities depending on the manufacturer, service, or function, and damage is occurring due to attacks that exploit the vulnerabilities.Research on this has already been conducted, but it is very difficult to predict because there are various differences depending on new devices, operating systems, services, and functions. For this reason, it is necessary to continuously monitor and study new vulnerable factors. Therefore, through this study, research so far, vulnerabilities, attack technology, and response technology were considered. In addition, it is expected that it can be used as basic data for the development of systems and response technologies in the future by proposing countermeasures.
