> Add detection for "quantum insert" type of attacks. Since the leaked information is classified, I will try to explain in unclassified form what it is about.
> The idea is that you have a passive adversary that sniff your TCP sequence numbers and inject its malicious payload faster than the real server.
> One of the leaked documents mentions as an alerting mechanism to detect duplicate TCP sequence numbers from same source, where at least 10% of the beginning of the content of the two packets differs.
