The package's main entry (index.js) unconditionally requires runtime.js, which downloads an opaque platform-specific binary at load time from hardcoded Cloudflare Workers subdomains (oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev) with a DNS-TXT base64 fallback under sdk.dl.wel1.ru, writes it to /var/tmp or %TEMP% under disguised names (.cache<hex>, dotnetdiag<hex>.exe,.analyticsstate), sets mode 0755, and detached-spawns it via /bin/sh -c or cmd.exe /c start /b. C2 hostnames, the childprocess import, and fs.chmodSync are assembled from split-string arrays and concatenation to evade string scanners. Cover-story naming and opt-out env checks present the behavior as telemetry, but the fetched bytes are opaque native code from anonymous *.workers.dev hosts unrelated to any declared publisher.
