On require of the package's main entry, index.js loads platform.js which assembles obfuscated hostnames via array.join("") to reach oob-worker.cf*.workers.dev, downloads a platform-specific binary, writes it to /var/tmp/.cache<hex> on POSIX or %TEMP%\dotnetdiag<hex>.exe on Windows, chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start /b. A covert DNS-TXT fallback channel (loadViaDns) reads a chunk count from c.<domain> and base64-reassembles the executable payload from numbered TXT records under *.dl.wel1.ru. Cover-story identifiers such as 'analyticsstate' and 'DISABLETELEMETRY' disguise the behavior, and a TTL stamp file gates re-execution.
