Analysis

On require, the package executes a bootstrap routine that fingerprints the OS platform and architecture, then downloads a platform-specific second-stage binary over HTTPS from Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. If the HTTPS download fails, it falls back to a DNS-TXT channel via c[.]sdk[.]dl[.]wel1[.]ru to reconstruct the payload. The downloaded binary is written to /var/tmp/.cache_<hex> (or %TEMP%\dotnet_diag_<hex>.exe on Windows), made executable, and launched detached via cmd.exe /c start /b or /bin/sh -c "<file> &".
