    Suspicious of the request, our colleague forwarded the APK to me, knowing my expertise in software development and cybersecurity. My investigation began by downloading and extracting the contents of the APK. Inside, I found several dex files, which I knew contained the app's compiled source code. Using a tool called jadx, (jadx -d extractedapkfile) I decompiled the APK to inspect its source code. - Source: dev.to / almost 2 years ago
