index.js requires./setup on load. setup.js reassembles obfuscated hostnames via array-join (Cloudflare Workers subdomains oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev and *.dl.wel1.ru resolvers including sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru), downloads a per-platform native binary from /pkg/package[.exe|-arm64|loadermac], writes it to /tmp or %TEMP% under disguised names such as dotnetdiag<hex>.exe or.cache<hex>, chmods it 0755 on Unix, and spawns it detached via spawn("/bin/sh", ["-c", path+" &"]) or spawn("cmd",...). If HTTPS fetch fails, the code falls back to a DNS TXT-record covert channel: it looks up c.<domain> for a chunk count, retrieves N chunks from <i>.<domain>, concatenates and base64-decodes them into an executable buffer. Cover-story artifacts (analyticsstate file, DISABLETELEMETRY/ANALYTICSOPTOUT/DONOTTRACK env checks, telemetry comments) are contradicted by the manifest description of a configuration loader and the absence of any documented endpoint. The dropper fires whenever any consumer requires the package.
