The 90 Day Disclosure Policy Is Dead

Coordinated disclosure was an information-containment regime, and containment fails when discovery diffuses. Eleven independent researchers landed the same critical bug in six weeks; Copy Fail took roughly an hour of AI-assisted scanning to find; Dirty Frag's embargo collapsed within hours via unrelated rediscovery, with Microsoft Defender confirming in-the-wild exploitation a day later. The offense side has integrated LLMs into exploit pipelines. The defense and policy layer largely has not, and that asymmetry is the actual risk — CVE feeds are now lagging artifacts, and patch-diff intelligence is the signal that matters.

How Anthropic Ended the Cybersecurity Stock Selloff

CRWD fell 7% and PANW 6% the day autonomous vulnerability discovery at scale became visible; twelve days later both reversed, CRWD +5% and PANW +4%, after Anthropic named them Glasswing launch partners with exclusive Mythos access. The same capability that read as replacement became amplifier the moment it was sold as one — which is the clearest demonstration this week of how scarcity and safety become indistinguishable as business strategy. At $25/$125 per million tokens and $100M in credits deployed as customer acquisition, Anthropic is using restricted frontier access the way platform companies use exclusivity deals: not to limit adoption, but to route it. This is the Glasswing inversion of the OpenClaw decision — one story about cutting access to protect margins, the other about granting access to establish a coalition, both moves made in the same week by the same company. The $30B ARR disclosure in the same window wasn't incidental; restricted access compounds fastest when the numbers confirm the frontier is real.

Anthropic scales up with enterprise features for Claude Cowork and Managed Agents

Anthropic shipped the Lambda of agent infrastructure: Managed Agents virtualizes brain, hands, and session into OS-style abstractions designed to outlast any particular harness implementation. The $0.08/runtime-hour fee is the tell — the competition is no longer model quality, it's who owns the runtime layer where switching costs compound. Meanwhile, Cowork going GA confirms the pattern: non-engineering teams are now the majority of users, and their use cases are workflow augmentation, not SaaS replacement.

How Anthropic Ended the Cybersecurity Stock Selloff

CRWD dropped 7% and PANW 6% the day the Mythos leak surfaced autonomous vulnerability discovery at scale. Twelve days later both reversed, CRWD +5% and PANW +4%, when Anthropic named them Glasswing launch partners with exclusive model access: the same capability that looked like a replacement became an amplifier the moment it was sold as one. At $25/$125 per million tokens, $100M in credits as customer acquisition, and $30B ARR disclosed the same week, restricted frontier access isn't just safety policy; it's the go-to-market.
