1. A computer-implemented method for identifying repackaged files, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising: identifying an application package that packages files for a mobile device application that is to be executed through a mobile device operating system; identifying, within the application package, a resource file that identifies resources for the application package defined in a programming language for the mobile device operating system; parsing the resource file to identify a flag for a resource that specifies whether the resource is public; determining that the flag for the resource has been set as public, the setting of the flag as public indicating that an identifier for the resource is prevented from changing between builds of the application package; classifying the application package as repackaged based at least in part on the determination that the flag for the resource has been set as public.

The computer-implemented method of claim 1 , further comprising checking whether a flag for the resource has been set as public within a different version of the application package.
