Reverse engineering and pentesting for Android applications

JPEX Software is a comprehensive reverse engineering suite for SWF binary files, serving as an ActionScript decompiler and editor. It provides a toolkit for decompiling, analyzing, and modifying the internal structure of compiled Flash content, including the extraction of scripts and media assets. The project is distinguished by its ability to perform direct binary modification, allowing users to edit bytecode and replace embedded resources without reverting to high-level source code. It includes a runtime ActionScript bytecode debugger for variable inspection and call stack analysis, as well

本项目是一个全面的 Android 逆向工程套件，具有反编译器、字节码去混淆器和恶意软件分析工具的功能。它旨在将 APK、DEX 和 OAT 二进制文件转换为人类可读的源代码，并使用无需 Java 虚拟机 (JVM) 的原生实现。 该平台通过与 Frida 集成进行动态分析而脱颖而出，允许用户实时挂钩方法、注入自定义 JavaScript 并转储设备内存。它还具有专门的安全引擎，包括污点传播引擎和栈状态机，以检测隐私泄露、恶意行为和安全漏洞。 该套件涵盖了广泛的分析功能，包括二进制补丁和重打包、交叉引用依赖映射和数据流分析。它提供了用于软件加壳识别、加密字符串解码以及跨应用程序资源进行全局元数据搜索的工具。 该工具提供命令行界面，并支持通过自定义 Python 或 Java 脚本进行分析自动化。

Fernflower is a Java bytecode decompiler and reverse engineering tool. It transforms compiled Java class files back into human-readable Java source code to reconstruct original program logic and variable names. The tool functions as a command line bytecode processor capable of batch processing Java archives and class files. It specifically handles obfuscated code analysis by renaming ambiguous identifiers and resolving naming conflicts to make the resulting source code easier to follow. The system employs static analysis to convert bytecode to source, utilizing debug information extraction t

python-uncompyle6 is a Python bytecode decompiler and reverse engineering tool designed to convert compiled bytecode files back into human-readable source code. It functions as a source code recoverer and bytecode disassembler, allowing for the analysis of internal program logic and the reconstruction of original language constructs. The tool provides cross-version support, enabling the analysis and recovery of source code from bytecode created across multiple different versions of the Python interpreter. This allows it to operate as a cross-version bytecode analyzer that can interpret varied

pycdc is a reverse engineering toolset that decompiles and disassembles compiled Python bytecode files back into readable source code. It parses .pyc file headers, reconstructs abstract syntax trees from bytecode instructions, and handles version-specific opcodes across Python versions 1.0 through 3.13 with endian-aware binary parsing. The tool recovers numeric constants, string literals, and marshalled Python objects from compiled bytecode, supporting both file-based and in-memory bytecode loading. It provides a human-readable disassembly listing of bytecode instructions alongside full sourc

Fernflower is a Java bytecode decompiler designed to convert compiled Java class files back into human-readable source code. It functions as a bytecode analysis tool that recovers original program logic and structure from compiled binaries. The project includes capabilities for obfuscated identifier resolution to rename ambiguous member elements, ensuring clear identifiers in the resulting source. These features support the analysis of obfuscated code, legacy code recovery, and Java malware analysis for security auditing. The system utilizes a structural analysis pipeline that includes contr

gdsdecomp is a project recovery suite and game engine reverse engineering toolset. It functions as a bytecode decompiler, binary resource converter, and asset extraction tool designed to reconstruct original directory hierarchies and scripts from compiled binary game assets. The toolset specializes in GDScript bytecode decompilation and compilation, translating compiled bytecode back into human-readable source code or converting source code into executable bytecode for specific engine versions and commit hashes. It includes a game archive patcher to modify project archives by replacing intern
