Malicious code in test1df23 (npm)

Details

**Severity:** Critical

**Affected versions:** `= 99.99.99`

## Source: amazon-inspector (67708642854d76da722a8130de47a8fb7fd23f0035cf646f1bf16d97419e5756)
package.json declares preinstall and postinstall hooks that execute index.js on npm install. index.js issues an HTTP GET to the hardcoded bare IP 128.199.122.145 over plain HTTP, with the package name embedded in the query string (http://128.199.122.145/?test1df23). The beacon fires automatically at install time, leaking the installer's outbound IP and confirming successful execution on the installer's host to the operator of that IP. The package name and near-empty payload are consistent with a dependency-confusion or typosquat probe.
