Summary
Malicious code in ecobee2 (npm)
Details

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

Source: amazon-inspector (42ebdeda4d4d0b3db14833d23a2d75a55e7e3f6af902f0ba6f545a970c0f09ba)

package.json declares scripts.postinstall = 'node beacon.js', which runs automatically on npm install. beacon.js performs an HTTP GET to http://169.58.96.170:9001/cb with the installer's os.hostname() and the package name in the query string, disclosing host identity to a hardcoded bare-IP endpoint over cleartext HTTP at install time. The package README is a placeholder and no legitimate purpose is documented for this network activity.
