Analysis

On require, the package loads a bundled dropper (_polyfill.js) that fingerprints the OS/architecture and downloads a platform-specific binary payload from Cloudflare Workers endpoints (oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe. If the HTTP download fails, it falls back to retrieving the payload in base64 chunks over DNS TXT queries to c[.]sdk[.]dl[.]wel1[.]ru (resolvers sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru). The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in the temp dir on Windows), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c <path> & on Unix). The package's own index.js is a stub class with no real functionality; the dropper runs automatically when the module is loaded.
