Curious, assuming such an signal is found, are there safety measures in place to isolate it from other systems in off chance it contains “alien malware” that attacks systems receiving it?
An alien signal for which the act of perceiving it causes some paradox that results in the perceiver to have never existed, cascading to every other interaction they've ever had (not had).
It's a clean and efficient way to nip upstart intelligences in the bud, before they advance far enough to start pulling at loose threads of the fabric of reality (which would threaten the remaining older intelligences, who survived and learned from previous such incidents).
