Google is working harder on providing better information to webmasters and the effects are showing. The Google blog has announced that they will send detailed information in their malware notifications to webmasters. These notifications will also be sent by mail.
Now instead of simply informing webmasters that their sites have been flagged and suggesting next steps, we're also showing example URLs that we've determined to be dangerous. This can be helpful when the malicious content is hard to find. For example, a common occurrence with compromised sites is the insertion of a 1-pixel iframe causing the automatic download of badware from another site. By providing example URLs, webmasters are one step closer to diagnosing the problem and ultimately re-securing their sites.
However, when it comes to email notifications, Google will send these mails to "likely webmaster aliases for the domain in question (e.g., webmaster@, admin@, etc)" for lack of a method for determining the real e-mail addresses. There is an extra bit of concern in this too:
We considered using whois records, but these often contain contact information for the hosting provider or registrar, and you can guess what might happen if a web host learned that one of its client sites was distributing badware.
