Hmm - it seems that once again it is proved that security only keeps
honest people out!

Not at all; this article shows how far SSH raises the bar. It's only possible to recover passwords this way if you already have root access on the box being SSHed into, as opposed to telnet where anyone along the path can trivially capture packets. And if you're using key-based authentication (as hoiho does) the only thing sent to the server is a one-time random challenge which cannot be reused for any subsequent login.

It's impressive that SSH can provide security to the point that even the admins of the box you're connecting to (or a malicious attacker who's gained root access) can only authenticate you, but don't get given enough information to impersonate you on other servers where you're using the same key pair.
