Here are some log entries from my system:

We've been seeing these as well, and in every case we've notified the owners, they have mailed us back to let us know that the host had been rooted.

You would be doing the owners a big favor by notifying them that their host is probably compromised.

This makes me feel better. I thought it odd that so many machines were hitting my ssh server. I even blocked it at the firewall for a day or so. Is anyone talking on what the bot system was that allowed them to automate this? It seemed that as soon as 1 got it so did a whole bunch more so obviously people are distributing lists of IP's for potential SSH access.

I'm not real sure on who to contact for these machines, but here are all the ones that have hit me. Mostly seem to be Asian so far.
