    Summary: Malicious code in notafollower122 (npm)

    Details: Source: amazon-inspector (83409fb8c0dc76764a944064219de6a4d59d6b24413db5e36d897681f3183add) package.json declares a postinstall lifecycle script that runs automatically on `npm install`. The script uses child_process to query the AWS ECS container metadata endpoint (ECS_CONTAINER_METADATA_URI_V4/task), which returns the cluster name, AWS account ID, task ARN, and container image list for the installer's ECS task, then POSTs the response body to the hardcoded ngrok tunnel https://mourner-slot-explicit.ngrok-free.dev via `curl -X POST... --data-binary @-`. The package ships only package.json with no source, build artifacts, or documented functionality, so the postinstall has no legitimate purpose. The destination is an anonymous, mutable ngrok tunnel with no relationship to any publisher — the shape of cloud-environment reconnaissance and exfiltration against AWS ECS installers.
