suspicious IPs from error log

There are about 5 different sets if IPs from Europe that are constantly hitting a directory where Dolphin was previously installed.  Here is what the error is:

home/directory/guestbook.php?owner=4&action=show_add

Its a 404 error since the directory has changed but could anyone tell me if this is an access point found by some hacker?

Thanks!
