DexX: A Double Layer Unpacking Framework for Android

摘要: In recent years, many packing services emerge and have been used to protect Android applications by concealing the executable files. However, it also brings some severe problems. For example, malwares use packers escape detection from anti-virus engine, which makes harder filter out malicious applications. At present, existing unpacking exploits are designed complicated not adaptive for new packers, unpackers always failed keep up with techniques. this paper, we propose a universal framework named DexX extract dex files protected these services. We apply packed applications, experiment results show that our can recover original (dex files) most well-known commercial effectively accurately.
