objection is a runtime mobile exploration toolkit that leverages Frida to inject a JavaScript agent into iOS and Android applications, enabling dynamic analysis, security mechanism bypass, and sensitive data extraction without requiring jailbreak or root. The system consists of a Python CLI (built with Click and prompt_toolkit) that connects to a Frida device, injects a TypeScript-compiled agent, and provides an interactive REPL for executing hundreds of commands organized by platform and category. It also includes a Flask-based HTTP API for remote interaction. Key entry points include 'objection explore' (attach to a running app), 'objection start' (launch and attach), and 'objection patchapk'/'patchipa' (inject Frida gadgets into mobile packages). The agent exports RPC methods for platform-specific operations such as hooking, heap exploration, filesystem manipulation, SSL pinning bypass, keychain dumping, and cryptographic monitoring. External dependencies include Frida (dynamic instrumentation), Flask (API), Click (CLI), prompt_toolkit (REPL), and platform-specific tools (apktool, aapt, adb, xcodebuild). The architecture follows a command pattern with state management via singletons, a plugin system for extensibility, and a job system for managing hook lifecycles. While the codebase is well-structured and actively maintained, it relies on fast-moving Frida APIs and mobile OS-specific bypass techniques that may drift with platform updates.
