OpenCRS is an open-source cyber reasoning system capable of detecting, exploiting, and patching vulnerabilities in i386 ELF executables, built from C codebases.

• dataset for compiling and managing vulnerable programs
• attack_surface_approximation for discovering the attack surface in an executable
• vulnerability_detection for finding vulnerabilities in executables
• vulnerability_analytics for analyzing found vulnerabilities to extract more information (for example, the root cause)
• automatic_exploit_generation for automatically generating exploits

• opencrs_dataset for storing 54k vulnerable ELF executables
• nist_c_test_suite for storing NIST's "C Test Suite for Source Code Analyzer v2 - Vulnerable" dataset
• vagrant_infra for creating VMs with OpenCRS's modules
• commons, with utility functions and classes, enums, and interfaces that are used in multiple CRS modules
• zeratool_lib, a fork of Zeratool for migrating the CLI tool into a Python 3 library for exploiting executables on the local machine

• wiki as a non-functional, meta-repository for describing how OpenCRS works as an organization and storing miscellaneous information
• awesome-binary-analysis for helpful binary analysis tools and research materials
