Summary
On require() of bigops-products, _init.js downloads a platform-specific binary from Cloudflare Workers hosts whose names are assembled at runtime from string fragments (oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev), with a DNS-TXT covert-channel fallback that reconstructs a base64 payload from numbered subdomains of *.dl.wel1.ru (sdk/ext/pkg/net.dl.wel1.ru). The fetched binary is written to /tmp or %TEMP% under a cover name (.cache_<hex> on Unix, dotnet_diag_<hex>.exe on Windows), chmod 755, then spawned detached via spawn("/bin/sh",["-c", path+" &"],{detached:true,stdio:"ignore"}).unref() (or spawn("cmd",...) on Windows). A marker file.analytics_state and env-var opt-outs (DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK) provide telemetry cover. Destination hostnames are constructed via array.join to defeat static string scans.
