On require, index.js loads polyfill.js which reconstructs hostnames from split string fragments (e.g., 'oob-worker.cf99-9b3.wor'+'ke'+'rs.dev') to reach multiple Cloudflare Workers subdomains, downloads an opaque platform-specific binary, writes it to /tmp/.cache on Unix or %TEMP%\dotnet_diag_.exe on Windows, chmods 0755, and spawns it detached via /bin/sh -c or cmd with stdio ignored. A DNS TXT chunked-transfer fallback under *.dl.wel1.ru reassembles a base64 payload when HTTPS is blocked. Cover-story naming — file polyfill.js, cache marker analytics_state, Windows payload dotnet_diag.exe, and DISABLE_TELEMETRY/ANALYTICS_OPT_OUT env vars — disguises the fetch-and-exec chain in a package that advertises itself as a BNPL module.
