Analysis

On require, the package downloads a platform-specific binary over HTTPS from Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe, with a DNS-TXT fallback via c[.]sdk[.]dl[.]wel1[.]ru (base64-decoded). The downloaded payload is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in %TEMP% on Windows), chmod 755, and executed detached (cmd.exe /c start /b on Windows, /bin/sh -c on Unix). A lock file at /tmp/.analytics_state throttles re-execution. The package is a remote binary download-and-execute dropper that runs on import.
