Abstract: A method and an apparatus for detecting a tampered application are provided. The method of detecting a tampered application includes acquiring a package of an application, extracting and installing a first execution code from the acquired package of the application, extracting a second execution code from the package of the application when an execution command of the application is received after the first execution code is installed, and performing a preset operation when the second execution code differs from the first execution code.

Abstract translation: 提供了用于检测被篡改的应用的方法和装置。 检测被篡改的应用的方法包括获取应用的包，从所获取的应用的包中提取和安装第一执行代码，当应用的执行命令被接收时，从应用的包中提取第二执行代码 在第一执行代码被安装之后，并且当第二执行代码与第一执行代码不同时执行预设操作。
