OSS-CRS and other AIxCC finalists: OpenSSF's integrated distribution of ARTIPHISHELL, BugBuster, Lacrosse and others
================================================================================

OSS-CRS is OpenSSF's effort to integrate the open-sourced AIxCC finalist systems, including Shellphish's ARTIPHISHELL, BugBuster, all-you-need-is-a-fuzzing-brain and Lacrosse, so open-source maintainers can run them against OSS-Fuzz projects.

Maintainer: OpenSSF and the AIxCC finalist teams
Website: https://arxiv.org/abs/2602.07666
