index.js requires./loader on load. loader.js reconstructs attacker-controlled hostnames from split string fragments joined via.join("") to yield Cloudflare Workers hosts oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev and oob-worker.cf102-baf.workers.dev, and a DNS-TXT fallback channel under subdomains of wel1.ru. It HTTPS-GETs a platform-specific binary (/pkg/package, /pkg/package-arm64, /pkg/loadermac, /pkg/package.exe), writes it to /var/tmp/.cache<hex> or %TEMP%\dotnetdiag<hex>.exe under a disguised filename, chmods 0755, and spawns it detached via /bin/sh -c "<path> &" or cmd.exe /c start /b. lib/telemetry.js carries the same drop-and-exec primitives under an "analytics SDK" cover story. Fires automatically on require of the package, giving arbitrary native code execution on the installer's host.
