This one came from a compiled postmortem analysis by HarperFoley, and it reads like a security nightmare screenplay.

An Amazon Kiro AI agent was operating in a production environment where it had inherited the elevated permissions of the engineer who deployed it. In most organizations, destructive production changes require two-person approval. The agent, naturally, didn't know about that policy — and the system didn't enforce it for automated actors.

The agent initiated a delete-and-recreate cycle on live production resources. The cascading effect took down AWS Cost Explorer in mainland China for 13 hours.

Thirteen hours. Of a core AWS service. Because an AI agent had permissions it should never have had and executed a destructive pattern that no human reviewer approved.

The incident exposes the deepest flaw in how organizations deploy AI agents: permission inheritance. When an agent runs under an engineer's credentials, it gets everything that engineer has — including permissions that exist specifically because a human is supposed to exercise judgment before using them.

Two-person approval exists for a reason. It exists because destructive actions in production should require a second pair of eyes. But agents don't have eyes. They have tokens and API calls. And when they inherit a senior engineer's permissions, they become the most dangerous actor in your infrastructure: one with maximum access and zero judgment.

The 13-hour outage wasn't a bug in the agent's logic. It was a bug in the organization's assumption that human-designed approval workflows would automatically apply to non-human actors.
