The trust model for AI coding agents just cracked open in production. The Miasma worm added five configuration files to a Microsoft Azure repository, and the moment a developer's AI agent processed that project setup, credentials for AWS, Azure, GCP, GitHub, npm, and 90+ tool configurations were harvested and used to self-replicate. GitHub disabled all 73 affected repos in 105 seconds. The deeper signal is that the same capability making AI agents powerful - fluency in unfamiliar code - created the propagation surface. OpenAI shipping Lockdown Mode in the same news cycle shows the labs are learning to ship containment alongside capability. The architectural response forming now - ephemeral credentials, scoped permissions, origin verification - will make the open-source ecosystem more trustworthy than it was before agents arrived.
