Try to use spoofing after upgrades:)
If I'd only knew how, I would use spooping just to know the ranges that were already scanned and also to get the source code of your server and client...

But I guess spoofing is much more than ping and wget.
Of course, but right now it is totally impossible to do something with spoofing.
It has client verification, server verification, each message from client checking by checksum, TLS encryption, SPKI and so one and so one and so one.
Full “zero trust” and all letters from STRIDE:)
