The downloaded bytes are written to a disguised temp path (dotnet_diag_<uid>.exe /.cache_<uid>), chmod 0755'd, and spawned detached via spawn(\"/bin/sh\",...) or spawn(\"cmd\",...). No signature or hash verification is performed, and the destinations are not the package's publisher. Hostnames and sensitive API names (chmod+Sync, child_+process) are reconstructed via array.join(\"\") splitting to evade static analysis.
