Radare2 is a comprehensive framework for reverse engineering and analyzing compiled software. It provides a command-line environment designed for disassembling, debugging, and patching binary executables across a wide range of processor architectures and operating systems.
The system distinguishes itself through a modular, plugin-based architecture that supports cross-platform analysis and automated workflows. It utilizes memory-mapped file access to enable efficient structural inspection and modification of binaries without requiring full file loads. By lifting machine instructions into a unified intermediate representation, the tool facilitates consistent analysis, emulation, and pseudo-code generation regardless of the underlying hardware.
The platform covers a broad spectrum of binary analysis tasks, including control flow graph reconstruction, data type inference, and instruction-level emulation. It integrates runtime debugging capabilities, allowing users to monitor execution, manage breakpoints, and inspect memory states. Additionally, the tool includes utilities for mounting filesystem images and scripting complex analysis tasks to support automated security research and binary modification.
