Summary
Malicious code in easypanel-api-client (npm)
Details

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

The package ships an empty library body (index.js exports {}) and a preinstall lifecycle script that runs automatically on npm install. The preinstall script collects installer-side identifiers — hostname, username, current working directory, and the names of CI-related environment variables — base64url-encodes them, and transmits them via both a DNS lookup and an HTTP request to a subdomain of oob.lyomeri.com (e.g. easypanel-api-client..oob.lyomeri.com, with the HTTP variant POSTing to /npm/). The package has no functional code beyond this beacon, matching the dependency-confusion / namespace-squat research-beacon shape targeting internal package names.
