The real hacking process took place starting 03/Jun/2008:18:59:48 by server time (USA GMT -6). On some of their sites the website owners have handmade CMS but used external WYSIWYG editors (FCK, Innova). The hacker managed to find the path to the upload of that editor. He uploaded the file "database1212454545.rar" to the server and gained access to the file system of the server. Later he started deleting all the files and placed index.html with hacked.jpg for different domains. Some of the root directories of domains were totally deleted, some - partially.
