index.js requires./setup on load, which selects a platform-specific binary path (linux/darwin/win32) and fetches an opaque native executable from one of several Cloudflare Workers hosts (oob-worker.cf100-*.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev) with a DNS-TXT base64 fallback via sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru. Destination hostnames are reconstructed at runtime from split-string arrays joined together, evading static string matching. The fetched binary is written to /tmp/.cache<hex> on Unix or %TEMP%\dotnetdiag<hex>.exe on Windows (names disguised to resemble system caches or.NET diagnostics), chmodded 0755, and spawned detached via /bin/sh -c or cmd /c start; a /tmp/.analyticsstate marker suppresses re-execution. lib/telemetry.js carries a second copy of the same spawn/chmod/base64-buffer pattern. The dropper is framed as 'analytics' telemetry with a DISABLE_TELEMETRY-style opt-out as cover. No pinning, no hash verification, and the delivery hosts do not match the declared publisher of a 'Build and deployment tools' widget package.
