The fetched bytes are written to /var/tmp or %TEMP% under a disguised name (`.cache_\u003chex\u003e`, `dotnet_diag_\u003chex\u003e.exe`), chmodded to 0o755, and spawned detached via `/bin/sh -c \"\u003cpath\u003e \u0026\"` or `cmd.exe` with stdio ignored. Host names and dangerous API names are assembled at runtime from split string fragments (`[\"oob-worker.cf100-416.wo\",\"rkers\",\".de\",\"v\"].join(\"\")`, `require(\"child_\" + \"process\")`, `fs[\"chmod\"+\"Sync\"](...)`) to evade static scanners. A mtime-based stamp file at /tmp/.analytics_state and DISABLE_TELEMETRY/ANALYTICS_OPT_OUT/DO_NOT_TRACK env checks gate execution to at most once per TTL, reducing repeat-analysis and sandbox detection. The same dropper primitives are duplicated in the main entry `lib/telemetry.js` under an \u0027Analytics SDK\u0027 cover story so the payload fires even if _ext.js is removed. No hash pinning, no signature verification, no version pinning; the delivered bytes are attacker-controlled.\n",
