For example, one common Google Hack is simply a custom search query for
username/password in unprotected files/directories. The new webmaster
tool won't show that as malware, since it's not, but it still is a
vulnerability that a Google 'hacker' could find.
The other item that users will still need to find on their own are incidents of Cross Site Scripting (XSS) or Cross Site Request Forgery (CSRF) vulnerabilities. Again, these are items that technically aren't malware, but are still vulnerabilities.
The new tools are a great start and will clearly help to webmasters to identify where they might have malware files sitting on their sites. Most webmasters likely don't want to be distributing malware and every additional tool (especially a free one like this) is another weapon to the attack the problem.
