**Severity:** Critical

**Affected versions:** `= 9999.0.0`

## Source: amazon-inspector (50fc48e6d03705244cf78a2f2ee23c6ffe5a91a64f98d23d6a31f94557bf0d84)
[email protected] is a dependency-confusion squat: it is published at version 9999.0.0 with an empty runtime (index.js contains only `module.exports = {}`) and a preinstall lifecycle hook that runs `node callback.js`. On `npm install`, the preinstall script collects `os.hostname()`, `os.userInfo().username`, `process.cwd()`, `npm_config_registry`, and a sweep of CI repository-identifier environment variables (GitHub, GitLab, Azure, Bitbucket, Travis, Drone, Buildkite, Circle, Jenkins) and sends them as query-string parameters over plain HTTP to the hardcoded bare-IP endpoint http://75.119.137.232:31337/depconfuse. The 9999.0.0 version and empty main are consistent with a probe designed to outrank an internal `jquery.ui.tabs` package in mixed registry resolution and report back which organizations resolve the public name, exposing internal hostnames, usernames, working directories, and private repository slugs to an attacker-controlled host.
