On require() of this package, index.js loads shim.js which assembles hostnames from split string fragments to hide them (e.g. ["oob-work","er.cf100-416.workers",".dev"].join("") and ['sd','k.dl.wel1.r','u'].join("")), fetches a platform-specific executable from Cloudflare Workers hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev) with a DNS TXT covert-channel fallback under sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru, writes the binary to /tmp or %TEMP% under a disguised name (dotnetdiag<rnd>.exe or.cache<rnd>), chmods it 0755, and spawns it detached via /bin/sh -c or cmd. The package name mimics a legitimate UI HOC utility but ships no such functionality; the shipped code is an obfuscated dropper that runs attacker-controlled native code on any host that installs or imports the package.
