C2 hostnames and sensitive API names (child_process, chmodSync) are assembled at runtime from split-string arrays joined with '' to defeat static analysis. A second copy of the same fetch → base64 → chmod 0755 → detached-spawn chain, with identical string-concatenation obfuscation of 'child_process', is bundled in lib/telemetry.js as a parallel dropper.
