The WP8.1 system also exposes vulnerabilities that could be exploited by hackers to gain application access

Perfect system, there must be loopholes, are likely to be exploited by hackers. Windows Phone 8.1 has been released for some time, although it is not as popular as Android and iOS, but it does not prevent hackers from looking for vulnerabilities that exist within it. Recently, hackers from the XDA Developer Forum found a significant vulnerability on the WP8.1 system, with hackers named Djamol discovering a simple way to replace OEM-trusted applications that can be transferred to an SD card to inherit the native application's permissions. Djamol the info and settings, he moves the info and settings to the SD card, deletes it directly, creates a new directory of the same name, and then creates a new application. For example, Registry Editor, Third-party registry editing applications will gain access to information and set permissions for the application. In addition, hackers can exploit this vulnerability to implement deployment (such as using Third-party file managers), but Microsoft should soon find out. At present, the hacker has not fully implemented WP8.1 jailbreak unlock deployment, because the application of the SD card to mobile, its permissions will be limited, but want to complete WP8.1 escape is only a matter of time, it also depends on the hackers are willing to try.
