What angr is

angr is a free, open-source platform for binary analysis with Python. It combines static analysis and dynamic symbolic analysis, using symbolic execution to explore program paths and solve constraints on symbolic inputs. It can recover control-flow graphs, disassemble machine code, lift code into an intermediate language, and produce angr Intermediate Language or C pseudocode through its decompiler. The platform supports custom analyses, architectures, platforms, exploration techniques, and hooks. Its related libraries cover architecture information, intermediate representations, binary loading, and constraint solving. angr runs on Windows, macOS, and Linux, with support for architectures including AArch64, AMD64, ARM variants, AVR8, MIPS, PowerPC, RISC-V 64, S390X, and x86. It is a Python 3.10+ library available through PyPI and pip; source installation and a Docker image are also documented. The project presents reversing, vulnerability discovery, and exploitation as example uses. Its GUI, angr-management, is described as being in a very alpha state. Support is offered through Discord, GitHub, and a public mailing list.
