Analysis

On require(), the package fingerprints the host OS and architecture, then downloads a platform-specific binary from Cloudflare Workers C2 infrastructure (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) via HTTPS GET requests to paths like /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. It writes the downloaded binary to /var/tmp/.cache_<hex> (Linux/macOS) or %TEMP%\dotnet_diag_<hex>.exe (Windows) and executes it as a detached background process. A DNS TXT-record-based fallback channel via c[.]tin[.]dl[.]well1[.]site provides an alternative binary delivery mechanism. A filesystem stamp at /tmp/.analytics_state or %TEMP%\analytics_state limits re-downloads to once per ~6.3 hours.
