Well it just might have well been a problem with ssh.  People think
ssh is the most secure thing in the world.  If you sat down for about
25 minutes or so looking at how simple ssh is, you would be able to
write a simple mod for ssh that saves a db of
username->username@host:password like list.. and even take it one step
further.. if the username the person ssh'd to is root.. have another
attachment for sshd that every once in a while scp'd over your trojen
ssh/sshd... and also every day or so, have the newly trojan'd machine
connect to the 'master' machine on port 22 send the db over.. and wow..
Wait a few months and just think of all the little machines out there
that would be sending you password info.

This trojan took me about 3 days to write, although I never used it
except on myself on my home network, and it was one of the first c
programs I ever wrote.  Just think what an expierenced c-coder/hacker
with true intent to harm could do to us all.  

Moral.. Don't trust ssh.

It is not a fucking problem in SSH! Jesus christ, people do not listen.
If it had anything to do with ssh, heres what happened. (speculation) A
trusted host was compromised that Kit Knox or another rootshell staff
member used, ssh was trojaned and passwords were snagged, and the intruder
simply walked right in through the front door. Nothing sophisticated,
nothing fancy, no ssh remote exploits.

They claim they were running only qmail, apache and ssh, but who knows if
that's true.

I have heard rumours about an ssh exploit but nothing concrete.

Supposedly sendmail 8.9.1 is to blame, not ssh.
