I'm just showing you that protecting contents using ZIP password isn't a good idea. I was able to extract music files from password protected ZIP/OBB file of japanese rhythm games
Requirements:
Steps:
AndnixSH#
Requirements:
- apktool.jar or APK Easy Tool
- IDA Pro
- Notepad++
Steps:
1. Decompile the APK file using apktool.jar or GUI version, APK Easy Tool
2. Open Notepad++. Click Search -> Find in Files, select directory and Search "password" or "zippassword" in the whole decompiled APK folder
3. As in rhythm games, the "password" found in .js and .so file. js is just javascript that shows webpage. we are looking for .so file
4. Disassemble the .so file using IDA Pro and search "zippassword". You will find the password immediately
5. Open ZIP/OBB using 7-zip or Winrar and input the password.
Done and enjoy!
