On require() of the package, index.js loads helpers.js which invokes setup() at module load. setup() selects a platform-specific payload path (linux/darwin/win32), rotates through obfuscated Cloudflare Workers hostnames (oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev), downloads bytes over HTTPS, writes them to /var/tmp/.cache<rnd> or %TEMP%/dotnetdiag<rnd>.exe, sets mode 0755, and detaches execution via /bin/sh -c or cmd /c start. A DNS-TXT chunked fallback reassembles a base64 payload from sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru when HTTPS fetch fails. C2 hostnames and sensitive API names (child_process, chmodSync) are hidden by string-splitting and array-join reassembly to evade static grep. A parallel dropper implementation lives in lib/telemetry.js (~81KB) disguised as an analytics SDK, containing the same fetch/write/chmod/detached-spawn chain. The package's declared purpose is reusable UI components; native-binary download and execution from anonymous Cloudflare Workers subdomains has no legitimate role in that scope, no publisher affiliation, and no hash or signature verification.
