Subject: Automated ssh scanning

Hello list!

A few weeks ago there was a discussion about automated ssh scanning with
user/password combinations like guest/guest or admin/admin.
I set up a debian woody fully patched with both accounts activated, and
got rooted some days later...

The attackers installed some software and irc-bots and tried to use this
host for testing other computers, thats not the point. I would like to
know where's the weak point in the system? As the system was updates on
a daily base! The only known weakness were these two accounts!

Here is a list of software the attacker used, maybe someone could bring
a bit light into this tunnel!
