How I defeated an obfuscated and anti-tamper APK with some Python and a home-made Smali emulator.

The ease of reverse engineering Android apps has always been a problem. There are a lot of tools that try to make it harder on reversers to do their job. This post demonstrates an interesting approach, when all dex/java decompilers fail, use a Smali emulator (in Python) to test obfuscated code. Interesting.
