Not personally, I've used snort and some other custom logging code
to find exploit attempts in real time though.
Can you tell us what CGI apps are installed upon the box? Or
do the access logs should anything suspicious? It's clear that
Apache is the route into the system if you have files owned by
www-data - maybe mounting /tmp noexec would help?
(note: mounting /tmp noexec breaks apt often).
