of course! <slap>

it's a perl w0rm that was uploaded last night, now killed. Now to determine how it got in.

I found some output in the main apache error log that looks like wget was used to download a shellbot. But I can't figure out how wget was called, may be some PHP exec() call that is unchecked.


Anything in /tmp ?

Disable register_globals and allow_url_fopen.
Set open_basedir for any virtual hosts to the absolute minimum.

That will help a bit.



But I can't find it on the system yet or the data files it uses.

chkrootkit says all is clear.

mod_security is now being installed, belatedly. This server has only been up 1 week, sheesh.

thanks

It was most likely executed via a remote server. Look for URLs in the logs that fetch stuff from remote servers.



cheers,
Rainer
