Anthropic's claims about its Claude Mythos AI model are startling. It reportedly discovered thousands of software flaws, including zero-day vulnerabilities, across major operating systems and browsers - more than adversaries deployed in a decade. Independent verification is limited, but even if hype outpaces reality, the direction is clear.

This moment echoes the past. In 2017, the EternalBlue exploit, stolen from the NSA, fueled WannaCry and NotPetya attacks causing billions in damage. Mythos is an even bigger prize, and adversaries will not stop trying to obtain it.

Organizations must act now. For defenders, the landscape is asymmetric: attackers iterate at machine speed; defenders are slowed by compliance and change control. The response must include disciplined investment in three areas: sharpen and integrate existing security tools, build in-house threat hunting capabilities, and make every employee part of the defense.

Singapore's Cyber Security Agency has issued a letter to Critical Information Infrastructure owners, demanding board-level attention. The message: never waste a crisis. Build resilience now, not after the next breach.
