This comprehensive guide details the methodology for reverse engineering macOS and Mach-O binaries. It covers analyzing application bundles, deciphering Objective-C/Swift symbols, examining code signing and hardened runtime features, and performing both static (using tools like Ghidra, IDA) and dynamic analysis (using lldb, Frida) to aid in malware analysis and platform security research.

A comprehensive methodology for deep security testing of both Android (APK) and iOS (IPA) applications. This guide covers the entire workflow, from initial information gathering and static analysis (decompilation, code structure analysis) to advanced dynamic instrumentation, network interception, and bypassing modern security measures like SSL Pinning, Root/Jailbreak detection, and anti-debugging.

A comprehensive, multi-phase workflow guide for authorized reverse engineering of complex network protocols. Ideal for analyzing proprietary formats such as custom TCP/UDP binary protocols, Protobuf, gRPC, WebSocket frames, and reconstructing state machines from raw PCAP data. This guide covers data collection, field layout restoration, serialization recovery, and secure replaying.

A comprehensive framework for reverse engineering compiled, obfuscated, packed, or virtualized targets. This process is crucial for understanding the internal workings of binaries, APKs, firmware, and custom VMs before exploitation or solution. It supports static and dynamic analysis using advanced tools like IDA, Ghidra, and angr, covering complex anti-analysis techniques and deep code structure analysis.

This comprehensive guide outlines a structured methodology for conducting authorized security testing on desktop thick clients (Win/macOS/Linux). It covers critical attack vectors, including local storage analysis, Inter-Process Communication (IPC) vulnerabilities, network traffic interception, client-side trust boundaries, and advanced reverse engineering techniques using tools like IDA and Ghidra.

A comprehensive, structured guide for reverse engineering and analyzing managed .NET/C# binaries. This skill covers the full workflow, including initial identification (CLR check), deobfuscation (using tools like de4dot), static analysis via IL view (dnSpyEx), and dynamic debugging. It is essential for analyzing malware, red team tools, and patching compiled C# applications.

This skill provides a CLI-based workflow for Android APK reverse engineering. It covers APK unpacking, Java decompilation, smali modification, repackaging, Frida dynamic hooking, and optional native .so analysis. It leverages local tools such as jadx, apktool, frida, adb, ida-reverse, and radare2. Useful for analyzing login, signature, security, root detection, or certificate verification logic in Android apps, always in an authorized context.

Analyze binaries in Binary Ninja using HLIL/MLIL/LLIL, strings, imports/exports, cross-references, types, patching, and Python API or MCP HTTP automation for authorized reverse engineering.

Reverse JavaScript-based custom DSL/VM interpreters, non-standard WASM-like runtimes, and risk-control engines. Use when analyzing IIFE or switch-based opcode dispatchers, extracting instruction tables, recovering bytecode semantics, capturing VM state at runtime, or reconstructing execution flow.

Provides IDA Pro reverse engineering capabilities for analyzing binaries, PE/ELF/APK/DLL/SO files, firmware, and malware. Supports decompilation, password discovery, vulnerability analysis, and software cracking workflows. Uses deterministic scripts for HTTP server management and file opening to avoid known MCP schema and lock issues.

This skill guides the advanced process of reverse engineering vulnerabilities from vendor-released security patches (N-day). By performing binary diffing between patched and unpatched binaries, users can pinpoint specific code changes (e.g., new boundary checks, locks) to infer the original vulnerability class (e.g., OOB, Race Condition) and develop a working Proof of Concept (PoC) for weaponization.

Analyze binaries with radare2/r2 from the command line, including reverse engineering, disassembly, function analysis, imports/strings inspection, patching, binary diffing, hex inspection, and r2 scripting. Supports PE/ELF/Mach-O/DEX/WASM files and sub-tools like rabin2, rasm2, radiff2, and r2pipe.
