In an effort to help maintainers of open source projects combat security threats, the Open Source Security Foundation (OpenSSF) has created a mailing list called Siren to enable sharing of information about vulnerabilities. 

“While consumers and enterprises may have intelligence sharing structures in place, this does not always extend to the upstream open source community. OpenSSF Siren is an open source resource that fills this gap,” Christopher “CRob” Robinson, director of security communications for Intel Product Assurance and Security, and Bennett Pursell, ecosystem strategist at OpenSSF, wrote in a blog post

Siren enables sharing of information about exploited vulnerabilities as well as emerging threats that may become relevant to a project. 

It follows the Traffic Light Protocol Clear (TLP:CLEAR) guidelines for sharing intelligence, and its contributors come from diverse backgrounds to enhance the database of intelligence.

Anyone interested in signing up for the mailing list can do so here. As of this writing, the list has over 1,000 members already.

“By leveraging the collective knowledge and expertise of the open source community and other security experts, the OpenSSF Siren empowers projects of all sizes to bolster their cybersecurity defenses and increase their overall awareness of malicious activities. Whether you’re a developer, maintainer, or security enthusiast, your participation is vital in safeguarding the integrity of open source software,” Robinson and Pursell wrote.
