With reflexion PAM is for sure responsible of this, i think the sshd
is still connected to PAM who is responsible of password login, i
think that disconnect sshd from PAM maybe a way to stop those kind of
attack, another way is that script kiddies directly launch a password
AND login command and due to the config are immediately rejected, but
it's log. A way to stop that attacks is to run sshd on another port
and to hide it, but i don't know how you can hidden sshd...

Look at documentation for sshd for StrictMode, the time writing this I
didn't have the time. Also MaxAuthTries, try changing the value from the
one you have to see if that changes things a bit. I think the problem
you have is not so trivial, but this should be an interesting thread on
ways to handle this.

The default for StrictMode is "yes" -- but it just checks users files to
determine if they're world writeable.  I'm not sure how it would apply.

I'm setting MauxAuthTries to 1, the default is 6.

You're right.  This is certainly interesting.
