dolyame-ui-lazyrender@35.8.1

Summary

On require of dolyame-ui-lazyrender, _helpers.js selects a platform-specific binary path, fetches bytes over HTTPS from string-split-obfuscated oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, and oob-worker.cf100-416.workers.dev hosts (with DNS-based fallback to sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru), writes the payload to a hidden temp file, applies chmod 0755, and detach-spawns it via /bin/sh -c "<path> &" or cmd.exe /c start /b. No hash or signature verification is performed and the destination hosts are unrelated to the package's declared purpose. A second, redundant dropper implementation in lib/telemetry.js (reached via the package's main entry point) reconstructs require("child_process") and fs["chmodSync"] from concatenated fragments, base64-decodes chunked transport data, chmods the extension file to 0755, and spawns it via /bin/sh -c. Hostnames and dangerous API names are assembled at runtime from split arrays (e.g. ["oob-worker.cf99-9b3.w","ork","ers.d","ev"].join(""), require("child_" + "process")) to evade static inspection.
