GoKawiil's interpretation of the reporting above, not reported fact.
The scale of these monthly patch batches has grown sharply, which Microsoft attributes to its use of AI tools to find and fix vulnerabilities faster. An actively exploited zero-day in Outlook means attackers were already using the flaw before a fix existed, making prompt patching important for organizations relying on the email client.
