Anthropic Cyber Mission
Where it stands: Anthropic expanded its Cyber Verification Program to give verified security professionals broader access to its most capable models, then launched the Anthropic Cyber Mission and a free, opt-in OSS Scanner for open-source projects. The scanner uses Anthropic's strongest Claude models for periodic security scans, and 88% of audited high-severity findings were confirmed valid. Watch whether that validity rate holds as scanning scales.

- 2026-10-25 (~12:00 PM ET, MarkTechPost — marktechpost.com/2026): the Oct 8 watch on OSS Scanner triage noise gets a first number — of the high-severity findings audited from its open-source scans, 88% were confirmed valid on review; the free scans run on Anthropic's strongest Claude models. Secondhand coverage (MarkTechPost, not Anthropic's own research post); sample size, project names, and validation method not in the reporting. Watch: whether the validity rate holds at scale, any OpenAI/Google scanner symmetry, and a first-party post with the denominator.
- 2026-10-08 the defender-access category becomes a standing operation — Anthropic announced the Anthropic Cyber Mission (Anthropic News, feed-anchored 8:00 PM ET Oct 7) and launched OSS Scanner (research post Oct 8; Verge 5:53 PM ET): opt-in, "thorough, periodic security scans by our strongest models at no cost" for open-source projects, "informed by our experience using Claude to find vulnerabilities during Project Glasswing." Delta on the Oct 6 Cyber Verification entry: gated access → mission org + public product. Watch: eligibility/mechanics docs, OpenAI/Google scanner symmetry, OSS triage noise as the second-order cost.
- 2026-10-06 The defender-access ask gets machinery — Anthropic expands its Cyber Verification Program (anthropic.com news post, feed-anchored ~8 PM ET Oct 5; X layer ~3 PM ET Oct 6): broader access to its most capable models for verified security professionals — operationalizing the Sep 30 policy ask (Mythos 5.1 behind trusted access), mirroring Google's Fairwind gate; defender-access programs are now a two-lab standing category. Detail snippet-thin: eligibility, capability tier, unverified.
