>
> 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.
