OpenSSF sings a Siren song to steer developers away from buggy FOSS

**OpenSSF has launched Siren**, a threat intelligence sharing initiative designed to aggregate and distribute real-time security bulletins and a community knowledge base for open-source software, bridging FOSS and enterprise communities. Siren will share TTPs and IOCs related to recent incidents as a post-disclosure channel rather than a place to reveal new flaws, addressing the growing need highlighted by supply-chain incidents (e.g., xz, Log4Shell) and studies showing widespread vulnerabilities in open-source components.
