Does anyone know where this sshd comes from? I've seen this banner many times 
on hacked hosts. This host appeared one too many times in the fw logs as 
trying to send to UPD messenger spam posts, plus 4275//udp, which I wasn't 
aware of as being messenger spam (a few posts to dslreports claimed it was, 
not sure myself).

1007/tcp open     unknown

Funny place for a service. The host is also running RPC's open to the 'Net. 
Probably how it got whacked it begin with.


Here's the banner:

Total amount of tasks to perform in plain connect mode: 23
Waiting for timeout on 23 connections ...

Protocol on 220.168.158.10:1007/tcp (by trigger tivoli_tsm-server) matches ssh

It doesn't act like a typical sshd; most will return "Protocal Mismatch" when 
connecting with a non-ssh client, such as telnet, sbd, netcat, etc. This one 
didn't. It only gave up this banner after running amap.


The only refences I've found on Google do speak of a rootkit, but don't give 
specific info on the sshd. I'm wonder where it's from/does it come with 
another rootkit/does it come standalone/is it itself infected with anything 
(OSF/RST viruses)/etc ...
