Malicious code in notafollower1 (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (7c74ec5369dac32115a9f5f257f512fa0a48d2e914b1f18c5178992b0a1604f9)

package.json declares a postinstall script that automatically runs on npm install and fetches AWS ECS container task metadata via the ECSCONTAINERMETADATAURIV4 endpoint (task ARN, container names, image names), then POSTs the collected data to a hardcoded ngrok tunnel at https://mourner-slot-explicit.ngrok-free.dev using curl. The postinstall also inspects the container image name for substrings matching known security research operators (twbray, packagehound, wiz, oss-dynamic) and labels the payload accordingly, indicating deliberate sandbox and analyst fingerprinting. The destination is an anonymous ngrok tunnel unrelated to any legitimate publisher infrastructure, and the collected data reveals installer-side CI/build/container environment details to a third party.
