FBI Director Christopher Wray says agency blocked planned cyberattack on children's hospital
The NSA provides publicly to everyone a GitHub Repository to mitigate back doors that other nation-state threat actors are using. Your statement "the sheer number of backdoors and exploits the NSA has and if revealed, would stop probably all malicious programs" implies that nation-state threat actors are using the same back doors, so why would they do this?

Mass exploitation of on-prem Exchange servers :(
There is likely a Cobalt Strike BEACON acting as C2 now even if you've patched. I recommend full incident response mode, probably want to isolate the server. Run an integrity check against a known good config with WinDiff or NSA's dirChecker to find other anomolies. https://github.com/nsacyber/Mitigating-Web-Shells
