Seriously Network Solutions? Seriously??
I can't see how Wordpress is to be blamed. All PHP scripts have the database passwords in plain text (Joomla, Drupal, Wordpress, PHPbb3, etc.) It's been that way for years and years... A little more fact checking is needed on his part. Wordpress's installer didn't install wordpress insecurly, Network Solutions' installer installed wordpress insecurly.
I also can't see how the user that uses the Network Solutions as Network Solutions installer does not install is in a secure fashion.
From the sounds of things, it does not sound like Network Solutions had their servers set up in a secure manner and a lot of people had to go through this ordeal because of it. It's Security 101: Don't give users access to other users files.
I can't believe this hasn't happened to them sooner! Hope they can secure their servers properly before the attack moves to the Joomla, Drupal, PHPbb3 and other PHP scripts.
Can I have the WTF AND the Fail icon on this one?
*shakes head at Network Solutions*
