The fetched bytes are written to /tmp or %TEMP% under disguised names (e.g. 'dotnet_diag_*.exe', '.cache_*'), chmod 0755, and spawned detached via child_process (spawn('cmd'...) or spawn('/bin/sh',...)). The package advertises itself as a 'platform adapter' / 'picture gallery' — remote binary execution is not the stated purpose.
