BSD-2-Clause馃К Reverse Engineering 路 Python
angr is a platform-agnostic binary analysis framework developed at UC Santa Barbara's Seclab. It combines both static and dynamic symbolic (concolic) analysis, providing a powerful Python API for analyzing compiled binaries without source code. angr can automatically explore execution paths through a binary, solve for inputs that reach specific code locations, recover control flow graphs, perform taint analysis, and identify vulnerabilities like buffer overflows and format string bugs. Its architecture is modular - SimOS provides OS abstraction, SimEngine handles execution, and the exploration strategies (DFS, BFS, coverage-optimized) guide analysis through the program state space. angr is widely used in academic research and CTF competitions, and forms the backbone of several automated vulnerability discovery tools.
Installation
pip
$ pip install angrDocker
$ docker pull angr/angrUse Cases
- Automated vulnerability discovery through symbolic execution of binaries
- Solving CTF reverse engineering challenges by constraining execution paths
- Recovering control flow graphs from stripped or obfuscated binaries
- Finding inputs that trigger specific code paths or crash conditions
- Building custom binary analysis tools on top of the angr Python API
