Interesting post over at Google blogoscoped, people have found a blacklist and a whitelist which is probably used for Google’s ‘safe browsing’ functionality. All that time I was thinking that Google had this ‘smart discovery’ for phishing sites, now it turns out that it is just a good old blacklist!
Oh, but wait, the fact that they also need a whitelist must mean that they do use some auto-discovery. Apparently it works a bit too well occasionaly, so they included a whitelist for sites that are known to be safe. Still interesting though.
Update: more about the lists can be read at the mozilla wiki, might be handy if you plan to use the lists in your own application.
