Patching Workflows Built for Weekly Cycles Can't Survive an Era of Hourly ExploitsAI is shrinking the window between vulnerability disclosure and active exploitation from weeks to hours. But remediation workflows haven't kept pace. Security teams need real-time intelligence, unified IT and security operations, and automated remediation to close the gap before attackers do.

Mythos Found ‘Tens of Thousands’ of Unpatched Flaws With Months to Fix ThemAnthropic CEO Dario Amodei warned that Claude Mythos has found tens of thousands of unpatched software vulnerabilities, with a six-to-12 month window before Chinese AI models catch up. The disclosure came alongside a major financial services push including an investor-backed firm and 10 new AI agents.

But Expect Plenty of Bottlenecks in Coordination, Validation and Patch DeploymentAnthropic's Claude Mythos Preview shows how AI can discover and chain vulnerabilities at scale, but the bigger challenge for defenders is redesigning disclosure, triage and patching processes so fixes can be deployed safely before attackers exploit the gap.

F5 Revises Severity of Flaw Disclosed Last YearFlaws in major application delivery and security platforms and VPN gateways are being actively exploited or targeted.
