ˇ GDA(GJoy Dex Analyzer)

GDA, an powerful Dal decompiler implemented in C++, which has the ad of fast analysis and low memory&disk consumption and an stronger ability to decompiling the apk, dex, odex, oat, jar, class, aar files.

GDA is completely nati and works without any Setup and Java VM, it works well in any new windows system and machine system without additional configuration. GDA Decompiler project started in 2013 and its first 1.0 released in 2015 at GDA website.

GDA is also a powerful and fast reverse analysis platform. Which does not only supports the basic decompiling operation, but also many excellent features like Malicious behavior detection, Privacy leaking detection, detection, Path solving, Packer identification, tracking analysis, Deobfuscation, Python& Ja, Device memory extraction, Data decryption and encryption etc.

All the features as follows:

𝕲𝕯𝕬 shortcut key

|shortcut |description|
|:-|:-|
|F5 |Switch java to smali, pressing it again for back to java|
|F |Trace the args and return-value by dataflow analysis|
|X |Cross-referencing, locating callers (of strings, classes, methods, field)|
|Esc/◄/Backspace |Back to the last visit|
|► |Forward to the next visit|
|G |Jump to somewhere by you inputting offset |
|N |Rename the /method/class name|
|S |Search for all the elements by the gi|
|C |Comments. Only supports the Java code|
|DoubleClick |The cursor's placed at the method/str/field/class, and double-click to access objects|
|M |The cursor's placed at the Smali line and pressing the key 'M' to edit the instruction|
|▲ UP |Press 'up' key to access the up-method in the tree control|
|▼ Down |Press 'down' key to access the down-method in the tree control|
|D |Dump the binary data of methods, only supports the Smali window|

|Ctr+H |Pop searching history window|
|Ctr+A |Select all|
|Ctr+C |Copy|
|Ctr+V |Paste, only for editable boxes|
|Ctr+X |Cut|
|Ctr+F |Find out the string of the code area|
|Ctr+S |Save the modifications into the GDA database file|

ˇ Installing

No installation required, just double-click the bin and you can enjoy it.
NOTE：
This is not an open source project，at least，in the short term. You can use the free tools and some open source scripts published here.

ˇ False positi

For copyright protection, GDA is protected by an authorized VMP, which may lead to false positives of some anti-virus software. Please ignore or add GDA to the white list. GDA does not have any malicious behavior.

GDA is embedded with ADB and gdump (used to dump device memory data), as well as , source-taint rules, api fingerprint etc. so, you will see some file in directory %APPDATA%/GDA. this behavior releasing the other executable files also be identified as a virus by some AVs.

ˇ Supported platforms

Only for windows

ˇ Usage:

## 1.GUI mode

Just drag a file into GDA, that's done.

If your files are .jar/.class/.aar files, you need the ja the dx tool. Please make sure that the ja properly.

When the analyzed jar file size is too big, it maybe takes a long time to analysize, please be patient.

## 2.CLI mode

*client_gda.py*

## 3.skills for LLM

An example of skill:

*gda_skills_test.py*

An example of analyzing the malware:

## 4.helper

*FAQ Summary*

*Brief Guide*

*How to search what you need*

*Support For Frida*

*Python Script*

*GDA Privacy Leak*

*GDA Path Solver*

*GDA APK Forensic*

*GDA Static Taint Analysis*

*Batch Decryption Of APP Strings*
