What is angr?

angr is a suite of Python 3 libraries that let you load a binary and do a lot of cool things to it:

Disassembly and intermediate-representation lifting
Program instrumentation
Symbolic execution
Control-flow analysis
Data-dependency analysis
Value-set analysis (VSA)
Decompilation

The most common angr operation is loading a binary: p = angr.Project('/bin/bash') If you do this in an enhanced REPL like IPython, you can use tab-autocomplete to browse the top-level-accessible methods and their docstrings.

The short version of "how to install angr" is mkvirtualenv --python=$(which python3) angr && python -m pip install angr.

Example

angr does a lot of binary analysis stuff. To get you started, here's a simple example of using symbolic execution to get a flag in a CTF challenge.

import angr

project = angr.Project("angr-doc/examples/defcamp_r100/r100", auto_load_libs=False)

@project.hook(0x400844)
def print_flag(state):
    print("FLAG SHOULD BE:", state.posix.dumps(0))
    project.terminate_execution()

project.execute()
