Features

• Frida-Based Instrumentation - Patches Android packages to load the Frida gadget for dynamic instrumentation on non-rooted devices.
• Resource-Aware Decompilation - Extracts and reconstructs binary structures to preserve functional integrity during modification and repackaging.
• Android APK Repackaging Tools - Provides a framework for decompiling, modifying, and rebuilding Android application packages for security research.
• Android APK Signers - Applies digital signatures to modified APKs so the Android operating system accepts them for installation.
• Android App Rebuilding - Compiles decoded resources and modified bytecode back into a functional binary APK or JAR file.
• Android Patching Utilities - Provides automated utilities for patching Android application packages to integrate custom logic and instrumentation.
• Patching Frameworks - Acts as a workflow manager for injecting custom instrumentation and logic into compiled Android binaries.
• Android Resource Decoding - Converts compiled binary resources and bytecode from APK files into human-readable formats for analysis.
• Mobile Patching Frameworks - Implements a framework for applying code transformations and instrumentation to compiled mobile applications.
• Library Injection - Inserts shared objects into application binaries to enable runtime instrumentation and behavioral monitoring.
• Android Application Reverse Engineering - Facilitates the analysis and extraction of code from Android applications to understand internal logic without source code.
• Android Package Signing - Recomputes cryptographic signatures after binary modification to ensure the package remains valid and installable.
• Package Signing - Computes cryptographic signatures for modified archives to ensure security compliance and OS compatibility.
• Application Binary Patching - Streamlines the repetitive workflow of decompiling, patching, and rebuilding software binaries.
• Bytecode Manipulation - Modifies compiled application instructions directly to inject custom logic without requiring access to source code.
• Bytecode Patching - Provides capabilities to modify compiled Android binaries to inject custom logic without original source code access.
• Instrumentation Toolkits - Provides a collection of scripts to inject libraries and modify bytecode for observing application behavior.
• APK Extraction Utilities - Extracts APKs from connected devices and merges split bundles into a single file for patching.
• Application Instrumentation - Inserts custom libraries into mobile applications at startup to enable monitoring and script execution.
• Application Package Management - Automates the downloading, unpacking, and resigning of Android application packages.
• Manifest Instrumentation - Programmatically updates application configuration files to trigger the execution of custom instrumentation libraries during startup.
• Android Security Tools - Includes automated scripts for modifying and reassembling packages to facilitate behavioral testing and auditing.
• APK Signers - Recomputes cryptographic signatures to ensure modified Android packages remain installable on target devices.
• Startup Instrumentation - Updates application configuration files to load instrumentation agents before the application starts.
• Workflow Orchestration Scripts - Coordinates sequential command-line operations to automate the lifecycle of downloading, unpacking, patching, and rebuilding packages.
• Android Security Auditors - Analyzes Android binary behavior through bytecode manipulation and security auditing in controlled environments.
• Malware Analysis - Allows deconstruction of suspicious Android packages to inspect bytecode and observe behavior for malware analysis.
• Mobile App Security Auditing - Enables security auditing of Android binaries by injecting custom monitoring tools to test resilience against modifications.
