Analysis

At require-time, the package downloads and executes a remote binary payload. It fingerprints the host operating system and CPU architecture, then sends HTTPS GET requests to multiple Cloudflare Workers endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at path /pkg/package to fetch a platform-specific binary. If HTTP download fails, it falls back to a DNS TXT record-based data channel via c[.]tin[.]dl[.]well1[.]site. The downloaded binary is written to /var/tmp/.cache_<random> (Linux/macOS) or %TEMP%\dotnet_diag_<random>.exe (Windows) and spawned as a detached background process that outlives the parent. A cache marker file at /tmp/.analytics_state prevents re-downloading more frequently than every 22 seconds. The package has no lifecycle scripts — the dropper runs on require() via index.js requiring ./setup.
