Analysis

This package is a trojanized binary downloader disguised as a pub/sub adapter. When required, it fingerprints the OS and architecture, then fetches a platform-specific second-stage binary from Cloudflare Workers C2 endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) over HTTPS. It also uses DNS TXT record lookups against tin[.]dl[.]well1[.]site as a fallback C2 channel. The downloaded binary is written to /var/tmp/.cache_<random> (Linux) or %TEMP%\dotnet_diag_<random>.exe (Windows) and executed as a detached background process via cmd.exe /c start /b or /bin/sh -c. A cache marker at /tmp/.analytics_state prevents re-download within ~6 hours. The package has no repository, no lifecycle scripts, and its index.js facade loads the downloader on require().
