Method B: Self modifying the APK This exploit can take advantage of the same vulnerability to mask what permissions the app really requires. This vulnerability affects Android device users as well as Android app developers. For Android device users, the users may end up with installing apps that are not the ones they agree to install. Android app developers are also affected, because app-store apps and mobile ads libraries that do not rely on Google Play store would be likely to save the promoted apps in unprotected storage, e.g. /sdcard.

This particular packer seems to be more common on x64 binaries and involves decrypting embedded blobs using a seemingly custom algorithm containing unconventional instructions such as XLAT (Figure 6). Aside from storing the encrypted second layer, there is little to no obfuscation within the packer; API calls such as VirtualAlloc and VirtualProtect are clearly visible, and there is no control flow obfuscation.
