I’ve been sitting with a thought for the past few weeks that I can’t shake.

Anthropic Claude Mythos is finding thousands of zero-day vulnerabilities autonomously. The security community is split between panic and denial. And I think both reactions are missing the point.

Here’s what’s been on my mind.

We’re asking the wrong question.

Everyone’s asking: “How fast will attackers weaponize AI for exploitation?

The question we should be asking: “Why are there still thousands of exploitable vulnerabilities sitting in critical infrastructure in 2026?”

Mythos didn’t create vulnerabilities. It found them faster.

Those vulnerabilities were already there. In your OS. In your browser. In the open-source libraries your entire stack depends on. The only difference is that now we know about them before someone silently exploits them for months.

And that’s actually good news.

The paradox that keeps me up at night

The same AI capability that terrifies security teams is the only thing that can save them.

Without AI, vulnerabilities sit dormant until a researcher stumbles on them, or worse, an attacker finds them first. With AI, they’re discovered at scale, disclosed responsibly, patched proactively.

Wiz recently framed this as a “Y2K moment.” I think they’re right, but not how most people interpreted it. Y2K wasn’t catastrophic because we prepared for it. We took the warning seriously and fixed the problem before the deadline.

Claude Mythos is our warning.

What I’ve been thinking about internally

Working in product at ArmorCode, I see this tension every day, the gap between knowing about risk and actually governing it at scale.

Our recent State of AI Risk Management report with The Purple Book Community put numbers to it: 90% of organizations claim visibility into their AI footprint, yet 59% admit shadow AI is present and ungoverned. If you can see it, why can’t you control it?

That gap between awareness and governed action is exactly what we built AI Exposure Management to close.

It’s not about another dashboard showing you that unsanctioned AI exists. It’s about converting that signal into owned, auditable decisions with clear accountability. (More on that here: https://www.helpnetsecurity.com/2026/03/04/armorcode-ai-exposure-management/)

This is the shift I keep coming back to. Detection without governance is just more noise.

Three shifts that need to happen now

From patch speed to secure design. If your security posture depends on out-patching attackers, you’ve already lost. “Assume breach” needs to evolve into “assume RCE.”

Zero-trust, blast radius containment, defense in depth, these aren’t buzzwords anymore. They’re survival requirements.

From tool procurement to AI integration. Security teams buying “AI-powered” tools without understanding the actual AI capabilities are doing security theater. Ask your vendors which models they use, how often they update, and what happens when Mythos-level models is publicly available.

From external threats to internal readiness. The debate about when attackers will get access to these models misses the point.

The real question: when will YOUR security team have equivalent capabilities?

Organizations that start building AI-assisted AppSec now will have hardened their infrastructure before attackers get similar tools. That’s the asymmetric advantage nobody’s talking about.

I built something to make this tangible

Talking about this in the abstract only goes so far. So I built a small interactive tool, an AI Security Readiness Assessment, that combines a vulnerability impact calculator with a security posture quiz.

You input your stack details and it estimates your exposure window: how long vulnerabilities sit undiscovered without AI-assisted scanning vs. with it. Then it scores your organization’s readiness across the three shifts above and gives you tailored action items.

Try it here: AI Security Assessment

AI Security Assessment

It’s a simple tool, but I think it makes the urgency real in a way that reading about it doesn’t.

The timeline

Based on how AI model capabilities have been progressing:

  • Now: Mythos-level capabilities are restricted to major vendors
  • 12-18 months: Open-source models reach similar capability
  • 24 months: These capabilities are commoditized

You have roughly 12-18 months to build the muscle memory for AI-assisted security before everyone else has the same tools. That’s your window.

The bottom line

Every vulnerability that Claude Mythos finds responsibly is one that attackers can’t exploit silently.

The AI security paradox is this: the thing we fear is the only thing that can save us. But only if we act.

The question isn’t whether AI will change cybersecurity. It already has. The question is whether your organization will adapt fast enough to benefit from it before attackers do.

What’s your take? Are you seeing this shift play out in your organization? I’m curious how different teams are approaching this.
