I agree, chances are the box hasn't been exploited just yet, but I
would be worried about just how he got that file there in the first
place. We know that directory is world writable, so it could have been
written by anything, but what? Sometimes the ownership of the file
will give it away, for example, if the file is owned by www-data, you
know some exploit in apache (usually php!) was used to gain file
system access.
