Open-source alternatives to Quark Engine

APKLab is an integrated security analysis platform and reverse engineering IDE for Android applications. It provides a unified environment for decompiling binaries into source code, repackaging modified applications into signed installers, and performing comprehensive security analysis. The platform distinguishes itself by combining static and dynamic analysis workflows. It enables the injection of runtime hooks and gadget libraries to monitor application behavior, while providing specialized patching capabilities to intercept and decrypt encrypted network traffic via a proxy. The toolkit co

Checkstyle is a Java static analysis tool and linter designed to identify and enforce coding standards and best practices. It functions as a code quality auditor and Javadoc validation tool, checking source code against configurable rulesets to ensure structural and stylistic consistency. The project allows for the creation of custom linting rules by extending a core API to inspect the abstract syntax tree. It further enables specialized validation through the use of XPath expressions to query the syntax tree for specific code patterns and violations. Capability areas include the enforcement

Android Package Inspector - dynamic analysis with api hooks, start unexported activities and more. (Xposed Module)

This project is a comprehensive Android reverse engineering suite that functions as a decompiler, bytecode deobfuscator, and malware analysis tool. It is designed to convert APK, DEX, and OAT binaries into human-readable source code using a native implementation that does not require a Java Virtual Machine. The platform is distinguished by its integration with Frida for dynamic analysis, allowing users to hook methods, inject custom JavaScript, and dump device memory in real time. It also features specialized security engines, including a taint propagation engine and a stack-state machine, to

droidefense (originally named atom: a nalysis t hrough o bservation m achine)* is the codename for android apps/malware analysis/reversing tool. It was built focused on security issues and tricks that malware researcher have on they every day work. For those situations on where the malware has…

A tool for quantitative risk analysis of Android applications based on machine learning techniques

Automated static analysis tools for binary programs

BlackDex is an Android runtime-level DEX extraction tool that recovers bytecode from protected APK files across Android versions 5 through 12 without requiring root access. It operates by hooking system APIs, reading DexFile cookies, and repairing obfuscated method bodies from memory, supporting both 32-bit and 64-bit architectures for installed and uninstalled applications. The tool distinguishes itself through a multi-method approach that combines cookie-based dumping, API hooking, and memory-based instruction repair to handle first through third generation packers. It reconstructs method b

WIP Crappy iOS app analyzer

Detekt is a static analysis tool, code quality linter, and complexity analyzer for Kotlin source code. It functions as a code smell detector and static scanner designed to identify potential bugs, design flaws, and violations of coding standards without executing the program. The tool differentiates itself through the use of issue baselining, which allows users to create a snapshot of existing legacy code issues to filter out old violations and focus on preventing new regressions. It further supports extensibility via a plugin-based system that allows for the integration of custom rule sets a

APKHunt is a comprehensive static code analysis tool for Android apps that is based on the OWASP MASVS framework. Although APKHunt is intended primarily for mobile app developers and security testers, it can be used by anyone to identify and address potential security vulnerabilities in their code.

idb is a tool to simplify some common tasks for iOS pentesting and research. Originally there was a command line version of the tool, but it is no longer under development so you should get the GUI version.

One-Step APK Decompilation With Multiple Backends

DroidLysis is a pre-analysis tool for Android apps: it performs repetitive and boring tasks we'd typically do at the beginning of any reverse engineering. It disassembles the Android sample, organizes output in directories, and searches for suspicious spots in the code to look at. The output…

Malware Analysis Tool using Function Level Fuzzy Hashing

File Scanning Framework

Infer is a static analysis toolset for Java, C, C++, and Objective-C designed to detect memory leaks, null dereferences, and resource bugs. It functions as a multi-language bug finder that identifies race conditions, deadlocks, and memory safety issues by translating source code into a common intermediate representation for analysis. The project distinguishes itself through an inter-procedural data flow analyzer that tracks movement between sources and sinks to detect tainted flows and generate data flow graphs. It also includes a framework for verifying temporal properties and reachability u

Easy to use cryptographic framework for data protection: secure messaging with forward secrecy and secure data storage. Has unified APIs across 14 platforms.
