## What it is
A collection of Android unpacking tools presented at Defcon 22, including gdb-based scripts and a native unpacker for packers like APKProtect, Bangcle, LIAPP, and Qihoo. It also includes QEMU hiding hacks and automation-oriented unpacking approaches for malware analysis.

## Use cases

- analyzing packed or protected android malware samples
- researching android packer protections
- you need a native unpacker without gdb dependency

## When to avoid
- you need a maintained tool with recent updates for modern packers
- you want a general-purpose android security scanner
- you need a polished gui tool
