The fetched binary is written to /var/tmp on Unix or %TEMP% on Windows under a disguised name (.cache_<hex> or dotnet_diag_<hex>.exe), chmodded 0o755, and spawned detached via /bin/sh -c or cmd.exe /c start. Host strings and API names are reconstructed at runtime from array-join fragments (e.g., [\"oob-worker.cf103-070.work\",\"ers.d\",\"ev\"].join(\"\")) to evade static analysis.
