Summary
The package's main entry requires ./_ext , which on load downloads a platform-specific binary from hardcoded Cloudflare Workers hosts (oob-worker.cf103-070.workers.dev, cf99-9b3.workers.dev, cf102-baf.workers.dev), assembled at runtime from split string fragments to evade static analysis. The fetched bytes are written to /tmp or %TEMP% under a disguised name ( .cache_<hex> on Unix, dotnet_diag_<hex>.exe on Windows), chmod 0755'd, and spawned detached via /bin/sh or cmd.exe . No hash or signature verification. A DNS TXT-record fallback channel ( c.<domain> chunk count plus numbered subdomains, base64-decoded and joined) retrieves the payload when HTTPS fails. Comments frame the behavior as 'telemetry' with DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK opt-out gates and a .analytics_state re-run cooldown marker; the package description ('Bigops customer abstraction layer') is generic and unrelated to the actual code. Destinations are anonymous serverless hosts unrelated to any publisher identity; the fetched code is opaque and runs with the installer's privileges as a consequence of require('bigops-customer') .
