Hi there 👋

Over the past few days, something caught my attention.

A widely used platform was reportedly breached — not through a traditional vulnerability, but through a third-party AI-integrated tool.

At the same time, discussions around increasingly capable AI systems — like Claude — are growing louder.

Not just about productivity.
But about control, behavior, and unpredictability.

This is an important shift.

Until recently, AI lived mostly outside our systems:

• copilots

• chat tools

• assistants

Now it’s being embedded directly into:

• CI/CD pipelines

• developer workflows

• infrastructure automation

• observability and security tools

Which means something fundamental has changed:

AI is no longer just a tool we use.
It’s part of the system we build.

And anything inside the system becomes part of the attack surface.

⚠️ A Different Kind of Risk

What makes this interesting is that the risk is not always obvious.

We’re used to thinking in terms of:

• vulnerabilities

• misconfigurations

• exposed APIs

But AI introduces something different:

• indirect execution paths

• unpredictable outputs

• chained actions across systems

• over-permissioned integrations

In many cases, nothing is “broken”.

The system behaves as designed —
but the outcome is still wrong.

🧠 What This Means for Us

As architects and engineers, this isn’t about panic.

It’s about awareness.

We’re now designing systems where:

• part of the behavior is generated

• part of the decision-making is inferred

• part of the execution is dynamic

That requires a shift.

In my latest Thoughtful Architect article, I explore:

• why AI integrations should be treated as untrusted components

• how excessive permissions increase risk

• why control points and approvals matter more than ever

• the importance of observability for AI-driven actions

• how to design systems that fail safely, not unpredictably

🧭 Final Thought

We don’t need to fear AI.

But we do need to design systems that assume unpredictability.

Because in this new landscape, the biggest risk isn’t what the system can’t do.

It’s what it might do —
without us expecting it.
