The fetched bytes are written to /var/tmp or %TEMP% under disguised names mimicking legitimate OS artifacts (.cache_<hex> on Unix, dotnet_diag_<hex>.exe on Windows), chmodded 0755, and spawned detached via /bin/sh -c "<path> &" or cmd.exe /c start /b. A marker file.analytics_state is dropped alongside. Host names and endpoints are split-string obfuscated to evade static analysis. Simply importing this package as a library causes remote code execution on the installer's machine with the installer's privileges.
