The retrieved bytes are written to /var/tmp or %TEMP% under a disguised name (.cache_<rand> on Unix, dotnet_diag_<rand>.exe on Windows), chmod'd to 0o755, and spawned detached via /bin/sh -c or cmd /c start. There is no pinning, no hash or signature verification, and the delivery hosts are anonymous Cloudflare Workers subdomains and a DNS-TXT channel — not a publisher-owned release surface.
