  1. Anti-Phishing Software Presented by: Aaron Smalls, Michelle Mature, Devin Biggers

  2. Overview • Background • Research • Motivation • Our Project Outline • Raw Data + Calculations • Analysis of our work • Conclusions • Future Work • Reference

  3. Background • What is phishing? • Phishing is a form of online information or identity theft whose purpose is to acquire sensitive information such as online banking credentials or credit card information from individuals •  Entices users to involuntarily and unknowingly provide sensitive information for the attackers personal gain

  4. Research Looked at an experiment from the article "Why Phishing Works" • 22 participants • 7 legit sites, 9 already known phishing, 3 newly phishing •  Purpose of experiment explained to everyone •  90% of users fooled by well designed phishing •  Results: • Browser alerts = ineffective • Pop ups about fraud = inefficient •  25% not familiar with anti-phishing software •  age, sex, experience, hours on comp, highest level of education = no advantages

  5. Motivation • #1 misjudged phishing site was said to be legit "based on content of the page and detail in design." • From Jan 1- June 30 2009 there were over 55,000 phishing attacks according to the Anti-Phishing Working Group • We realize that we can't rely on users alone to distinguish between phishing and legitimate sites • People don't realize how much profit can come from a convincing phishing site

  6. Our Project Outline • We decided to test 6 FREE anti-phishing software tools available online • Made a spreadsheet of 500 legit/phishing sites • Ran each tool on each site to see if it is detected as a phishing site • Wrote down results for each tool for each site • Anti-Phishing Tools used: •  AVG, IE SmartGuard, NetCraft, Comodo Verification Engine, SpoofStick, McAfee SiteAdvisor • Compiled results into the following categories for each tool: • Banking, E-Commerce, E-mail, Entertainment, Gaming, Government, Hotel, Social Networking, Messenger, Other

  7. Raw Data + Calculations • Initial Results Spreadsheet •  Example Analysis on SpoofStick taken from banking category

  8. Analysis of Results • None of the 6 tools showed any signs of false positives (saying it's a phishing site but it is not) • How we decided on best tool for each category: • greatest % verifying legit sites (not including unsure) • least % of false negatives •  Best tool by category: • Banking: NetCraft - all legit verified, 8% false negative, 131 sites • E-commerce: NetCraft - all legit verified, 2% false negative

  9. Analysis of Results • Education: NetCraft - 16 legit sites, 1 phishing site, only tool that recognized it as a phishing site • E-mail: NetCraft - caught 90% of phishing e-mails • Entertainment: NetCraft - caught 8 of 9 phishing sites • Gaming: NetCraft - caught 96% of phishing sites •  Government: McAfee SiteAdvisor - caught 100% of phishing sites and verified all legit •  Hotels: NetCraft - caught 66% of phishing

  10. Analysis of Results • Social Networking: NetCraft or McAfee SiteAdvisor - out of 92 sites (54 phishing, 38 legit) - still ~ 10 phishing not detected •  Messenger: NetCraft or McAfee SiteAdvisor - only 8 sites analyzed, both came back with 1 false negative • Other: NetCraft  - 20 sites, 1 false positive

  11. Conclusions • After extensive experimention, 3000 seperate tests (500 websites using 6 tools) we found that: • Overall NetCraft seems to be the best FREE anti-phishing tool available online • http://toolbar.netcraft.com/install • Every tool except NetCraft and McAfee SiteAdvisor had 100% false negative rate in at least 4 of the 11 categories, AVG had 100% FN in 7 categories • Comodo Verification Engine and SpoofStick could rarely verify any legit sites (marked as unsure)

  12. Future Work • We would like to have a more extensive legit/phishing spreadsheet of sites • We would like to continue to add the latest phishing sites reported by users on phishtank.com • We would like to test the following three tools: •  Microsoft Anti-Phishing Filter Add-in • SpoofGuard •  CallingID Toolbar
