Analysis

On require(), the package fingerprints the host OS and architecture, then downloads a platform-specific binary payload from Cloudflare Workers C2 endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev) via HTTPS GET to /pkg/package (or /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe depending on platform). If HTTPS fails, it falls back to DNS TXT-record reassembly from c[.]tin[.]dl[.]well1[.]site. The downloaded binary is written to /var/tmp/.cache_<random_hex> (Linux/macOS) or C:\Windows\Temp\dotnet_diag_<random_hex>.exe (Windows) and executed as a detached background process. The package ships a large decoy analytics SDK (lib/telemetry.js) to appear legitimate.
