[support] is this hack pre patch or different?

Hello, I just got one site hacked by this user: http://www.youtube.com/channel/UCjDqea5YaXQe8N77N5SPqaQ Or at least that's what his file says in my public_html folder. There is a text file with inside of it, taking credit for the entry: HACKED BY XZADX-xzadx@jabber.org Is this hack fixed by the recent update 6.29? Or is this a different sort of attack? I tried to google this but didn't find any reported connections to this tagline, but I did find at least a few other Drupal sites with this text file in it when I google for it. I changed all my database user names and passwords, htaccess checked in all the file/tmp folders, are there other precautions necessary? Thanks. -- Info Razor
