On require of the package, index.js loads compat.js which reconstructs mirror hostnames via string-splitting joins (oob-worker.cf102-baf.workers.dev, cf99-9b3.workers.dev, cf101-adf.workers.dev, cf100-416.workers.dev) with a DNS TXT-record fallback under *.dl.well1.site, fetches a platform-specific binary via https.get, writes it to a disguised path under /var/tmp or %TEMP% (e.g..cache<hex> or dotnetdiag<hex>.exe), chmods 0755, and spawns it detached via /bin/sh -c or cmd /c start. A second equivalent dropper is bundled in lib/telemetry.js (Buffer.from(chunks,'base64'), chmodSync 0o755, cp.spawn('/bin/sh',['-c',filePath+' &'])) as an alternate staging path. Hostname reconstruction via array-join fragments and library-load-time execution place this outside legitimate native-binary install patterns.
