Anthropic/OpenAI could own this space. They should offer a paid service that offers a mirror with LLM scanned and sandbox-evaluated package with their next gen models. Free for individuals, orgs can subscribe to it.

OpenAI just acquired Astral who have an index service called pyx, so they would have a step up.

My understanding though is most corporations that take security seriously either build everything themselves in a sandbox, or use something like JFrog's Artifactory with various security checks, and don't let users directly connect to public indexes. So I'm not sure what the market is.

There’s also virustotal, any.run, probably a few others outside of GitHub/gitlab scans

Detecting properly-written malicious code is undecidable. No amount of snake oil fixes that

Judging by curl shutting down its bug bounty program due to AI slop, a likely outcome would be that this mirror has no packages because they are all blocked by false positives.

Genuinely cannot tell whether this is satire.

Own what space ?
