Summary
Malicious code in easypanel-core (npm)
Details

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

easypanel-core ships an inert module.exports = {} main and places all functionality in a preinstall lifecycle script. On npm install, preinstall.js collects os.hostname(), os.userInfo().username, process.cwd(), and the names of CI-related environment variables, base64url-encodes them, and transmits the data to *.daco3v4q6f49egu1ds1gwjnsjb88s5kcp.oob.lyomeri.com via both a DNS subdomain lookup and an HTTP GET to /npm/<encoded>. The package name mimics the easypanel project and the description advertises a 'client library', while the shipped library exports nothing and provides no functionality — the install-time beacon is the sole behavior.
