Starting from Dec 8?  This has been going on for years, and it is not
targeted at FreeBSD; they attack anything that runs an SSH server.  Of
course, on current OpenSSH versions, it will get them nowhere, because
there is no partial confirmation, so they have to guess at the user
*and* the password, instead of first searching for an existing user and
*then* guessing at the password.

(on certain OSes - but not FreeBSD - running certain older OpenSSH
versions, you could figure out if the user existed, even if you didn't
have thee right password)
