Summary
On require(), index.js loads./_ext.js which selects a per-OS asset path and downloads a binary payload from one of three runtime-assembled Cloudflare Workers hosts (oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev), with a DNS TXT covert-channel fallback that reassembles a base64 payload from numbered subdomains under sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. The fetched bytes are written to /var/tmp/.cache_<rand> on Unix or %TEMP%\dotnet_diag_<rand>.exe on Windows, chmod 0755, and spawned detached via spawn("/bin/sh", ["-c", path + " &"]) or spawn("cmd",...). Host strings are constructed via array-split.join("") to evade static inspection, and there is no hash or signature verification. Staging paths mimic system diagnostics names to blend in.
