I've been trying to find some information on how Google Chrome detects phishing pages that are not already in their blacklists. The most relevant information that I've found from Google itself, states:
Second, Safe Browsing helps to protect you against targeted phishing attacks (sometimes called “spear phishing”), where a site may not already be known to Google so isn’t on the list of phishing sites. Chrome does this by analyzing the content on the site and warn you if it seems suspicious.
Does anyone have any more information on the specific type of "content analysis" that Chrome is doing?
