It fetches a platform-specific executable payload from those hosts, writes it to a randomly-named file in /tmp or %TEMP% with cover-story names (dotnet_diag_<rnd>.exe,.cache_<rnd>,.analytics_state), chmods it 0755 on Unix, and spawns it detached via /bin/sh -c or cmd /c start. The tarball also ships lib/telemetry.js, an ~81KB unreferenced sibling module implementing the same fetch-write-chmod-spawn pattern with base64-reconstructed payload bytes and string-concatenated 'child_'+'process' / 'chmod'+'Sync' references.
