3. 3 Comparative Analysis of Browser Anti-Phishing Techniques Background  Phishing can be defined as an attempt to obtain sensitive and personal information by masquerading as a trustworthy entity in some form of electronic communication.  This sensitive information includes, but is not limited to passwords, credit card numbers, and usernames.  As a result, all major browsers contain some type of anti-phishing measure, that is either turned on or off by default.  With an increase in the amount of spam that most email addresses receive, phishing has become more and more popular and it is important that we learn how to protect out information and detect these sites.

8. 8 Comparative Analysis of Browser Anti-Phishing Techniques Microsoft Phishing Filter in Windows Internet Explorer 7  Microsoft Phishing Filter, uses a combination of Microsoft’s URL Reputation Service (URS) and local heuristics built into the IE 7 browser.  These methods allow it to identify and warn users in real time of suspected phish URLs, and block them from accessing confirmed phishing sites that have been reported to the URS by either users or third-party data providers.

9. 9 Comparative Analysis of Browser Anti-Phishing Techniques Netscape Browser 9.0  Includes a built in phishing filter  Relies solely on a blacklist, which is maintained by AOL and updated frequently

10. 10 Comparative Analysis of Browser Anti-Phishing Techniques Opera  When Opera Fraud Protection is enabled, a server is contacted at Opera every time you request a Web page.  HTTPS sites are checked via an encrypted channel, while IP addresses on the local intranet will never be checked.  The server checks the domain name of the requested page against live whitelists compiled by GeoTrust, and blacklists compiled by GeoTrust and Phishtank.GeoTrust Phishtank  Opera's fraud protection server downloads blacklists directly from Phishtank, and sends a query to GeoTrust.

11. 11 Comparative Analysis of Browser Anti-Phishing Techniques Mozilla Firefox  Phishing Protection is turned on by default in Firefox 2 or later, and works by checking the sites that you browse to against a list of known phishing sites.  This list is automatically downloaded and regularly updated within Firefox when the Phishing Protection feature is enabled.

12. 12 Comparative Analysis of Browser Anti-Phishing Techniques McAfee SiteAdvisor Toolbar  McAfee's SiteAdvisor product is a free stand- alone anti-phishing product  Suspect or blocked sites are identified by a popup balloon and by color and text changes in the button.  SiteAdvisor offers a wealth of information about sites, including whether the site appears to send spam and whether it is suspected of being a phishing site.

13. 13 Comparative Analysis of Browser Anti-Phishing Techniques Netcraft Toolbar  Utilizes Netcraft's very large database of Web servers to flag suspected or actual phishing sites.  The toolbar displays several useful characteristics of the current page, including the country where the Web server is hosted, the true IP address, and a bar-graph "risk rating" indicator.

14. 14 Comparative Analysis of Browser Anti-Phishing Techniques GeoTrust TrustWatch Toolbar  The TrustWatch Toolbar combines site lookups with phishing protection and Google search.  The toolbar shows the real DNS name of the currently loaded site, and it allows users to specify a visual or textual identifier that the toolbar knows and can display; this helps guard against sites that put up their own fake address bars.

15. 15 Comparative Analysis of Browser Anti-Phishing Techniques How to rate Phishing tools  Catch rate: how well each tool catches known phish from a common pool of known phish, either by generating a warning or blocking access to the phish page.  False positive rate: how many false warnings or blocks each tool generates from a pool of known-good URLs.
