This does not seem to be a stupid brute force attack, as there is only
one login attempt per user. Could it be that the tool tries to exploit
some vulnerability in the sshd, and just tries to look harmless by using
'test' and 'guest' as usernames?

The compromised machine was running an old debian woody installation
which had not been upgraded for at least one year, the sshd version
string says 'OpenSSH_3.6.1p2 Debian 1:3.6.1p2-10'

Does the Debian machine that was compromised have a ``test'' or ``guest'' username?

Also, if it wasn't patched in a year, it may still be vulnerable to this: http://www.cert.org/advisories/CA-2003-24.html

I would tend to think this isn't a 0day kinda vuln, as if it were, he'd be a lot more successful than he seems (unless we're all rooted and don't even know it). But who can tell?
