A Tour of the Google Blacklist.

I recently decided to devote a day to walking through the Google 
Blacklist. While some of the findings were to be expected, others proved 
somewhat surprising. The Google Blacklist is a listing of URLs suspected 
to be phishing sites. It is used by the Google Safe Browsing for Firefox 
extension which is now part of the Google Toolbar for Firefox. It is 
also leveraged by the Firefox 2 web browser. Google maintains a number 
of different safe browsing lists to combat phishing including a URL 
blacklist, an encoded/hashed blacklist, a URL whitelist, a domain 
whitelist and a sandbox text list, which contains keywords included in 
URLs. While Google doesn't reveal exactly how these lists are developed, 
it's clear that user input is an important variable given that both the 
Google Toolbar and Firefox 2 allow for optional user feedback when 
phishing sites are encountered.
