What Does APK Mean?

The abbreviation APK is short for the Android application package file. An APK is a file format used to distribute application software and other digital assets for Android-based devices. It’s similar to a .exe or .dmg file download on PC. Nobody knows for sure where the term APK comes from, but it stands for Android Package Kit – Aquila Packed Kit.

These are the files that make up an android app and help to display the application on your mobile devices. The APK file format is used on other platforms, such as BlackBerry and Amazon’s Kindle Fire.

APK means Android Package (Application) File. It is the file format used to distribute and install applications on the Android platform.

APK file is a zip archive that contains application resources, assets (like images, libraries, etc), and source code files. These files are compressed using a gzip or Microsoft zip-compatible compressor.

APK is mostly used on Android and is one of the most security risk-associated files.

APK contains codes, it must be signed by the same certificate that is used by the app. Since

Android does not have any restriction to the certificate that can sign a package, attackers can use the self-signed certificate and distribute fake apps via Google Play Store.

To identify the difference between malware and an innocent-looking application, mobile threat researchers use static code analysis tools such as APK Injection, Jax, or BinDiff. These tools carry out decompilation of the application’s APK file and then compare it with a clean version of the same application.
