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.

DESCRIPTION

       glutSetCursor  changes  the cursor image of the current window.	Each call requests the window system change the cursor appropriately.  The
       cursor image when a window is created is GLUT_CURSOR_INHERIT. The exact cursor images used are implementation dependent. The intent is  for
       the image to convey the meaning of the cursor name. For a top-level window, GLUT_CURSOR_INHERIT uses the default window system cursor.

X IMPLEMENTATION NOTES

       GLUT for X uses SGI's _SGI_CROSSHAIR_CURSOR convention to access a full-screen cross-hair cursor if possible.
