Our system was hacked

Someone made a mistake, and left our router wide open, pointing all ports to a SCO 6.0.0 system.
Within 24 hours, the following happened.
The contents of all the files (except tar files) in three directories, one directory on each of three different file systems, were replaced with nulls. None of the inode data was changed, meaning that the output of 'ls -l' was the same before and after. In two of the directories the file permissions were 0664, and in the last, the permissions were 0644 and files owned by root.
I have not been able to find anything in any of the log files to indicate who or when this happened.
Since we had adequate backups there was no long term damage.
Any thoughts would be appreciated.

NAME

       Net::IRC::DCC - Object-oriented interface to a single DCC connection

SYNOPSIS

       Hard hat area: This section under construction.

DESCRIPTION

       This documentation is a subset of the main Net::IRC documentation. If you haven't already, please "perldoc Net::IRC" before continuing.

       Net::IRC::DCC defines a few subclasses that handle DCC CHAT, GET, and SEND requests for inter-client communication. DCC objects are created
       by "Connection->new_{chat,get,send}()" in much the same way that "IRC->newconn()" creates a new connection object.

METHOD DESCRIPTIONS

       This section is under construction, but hopefully will be finally written up by the next release. Please see the "irctest" script and the
       source for details about this module.

AUTHORS

       Conceived and initially developed by Greg Bacon <gbacon@adtran.com> and Dennis Taylor <dennis@funkplanet.com>.

       Ideas and large amounts of code donated by Nat "King" Torkington <gnat@frii.com>.

       Currently being hacked on, hacked up, and worked over by the members of the Net::IRC developers mailing list. For details, see
       http://www.execpc.com/~corbeau/irc/list.html .
