Do they all have the same root password? I have heard that some people
think it may be a root password compromise.
What else is there that is unique to this box?
I also heard that the exploit may be installed in some of the site code,
the entry point is elsewhere, but once infected, it installs the exploit
in source code for a site.

Update,
The problem box:
- centos 5 base, updated via yum from default repository.
- httpd 2.2.3-11.el5_1.centos.3 (2.2.8 backport?)
- php 5.2.5 compiled from source
- courier-authlib 0.60.2 compiled from source
- courier-imap-4.3.0 compiled from source
- exim 4.69 compiled from source
- proftpd 1.3.1 compiled from source
I have no control panel of any sort installed.
The box was running RH9.. had the issue.. formatted and replaced with
fresh install of centos 5... copied over customer vhosts..
Gets hit again within days.
ports open = 20,21,22,25,80,110,143,443 + pasv port range for ftp
I have many other hosts in the datacenter with various configurations
but all would have had the same apache, php, ssh, ssl versions as this
box before at RH9. None of them have been hit.. none of them however,
contain exim, courier, or proftpd
Im starting to lean towards these packages as a possible entry-point
for the trojan?
And no its not ARP or DNS poisoning nor router or proxy problems.

I don't think ARP cache poisoning is the problem here, unless client

Not necessarily.
Sitting on one of them subnet is way sufficient. More generally, you
need to be somewhere on the path between your two targets to perform a
traffic redirection. As routers and firewalls can be poisoned as any
other node and as they act as gateways, they are all the more
interesting targets.
