Radare2 and Frida have combined forces through the r2frida plugin, allowing users to leverage Frida's dynamic instrumentation capabilities within the radare2 environment. This self-contained plugin enables direct process instrumentation using radare2 commands, facilitating the execution of Frida scripts without requiring Frida to be installed on the host. Users can run unmodified Frida scripts, manipulate memory, and interact with processes locally or remotely, supporting various programming languages like C, JavaScript, and TypeScript. The plugin offers a wide array of functionalities, such as attaching to processes, listing symbols and methods, and replacing method implementations with simple commands. It supports multiple platforms, including Linux, Windows, macOS, iOS, and Android, and is compatible with architectures like x64, arm32, and arm64. Installation can be done through r2pm or manually by cloning the GitHub repository and compiling it, with specific package requirements outlined for different operating systems. Users can perform various tasks, such as tracing function arguments, reading and writing process memory, and sending signals to processes. The commands are structured to facilitate easy interaction, whether for local debugging or remote connections. The plugin also allows for the registration of custom scripts and plugins, enabling further customization and automation within the radare2 environment. Notably, the development of r2frida is credited to Sergi Alvarez, the creator of radare2, with significant contributions from Ole André, the maintainer of Frida.
