Vulnerabilities in many “tabbed” browsers that allow easy switch from one window to another Mozilla 1.7.3 Mozilla Firefox 0.10.1 Camino 0.8 Opera 7.54 Konqueror 3.2.2-6 Netscape 7.2 Avant Browser 9.02 build 101 and 10.0 build 029 Maxthon (MyIE2) 1.1.039
Tabbed Browser Problems (2)
• Dialog box can be spawned in active window from connection to an inactive window– E.g., visit PayPal– Get popup box to “verify” password– Actually comes from rogue site in different window
• Possibility of diverting data into a form on a different window for a malicious Website– Would try to enter data into form on legitimate site– Data would actually go somewhere else
Anti-Phishing Steps
Proclaim, Protect, Pursue• Proclaim in all correspondence the use of an
official mark (e.g. TrustedSender stamp)• Protect all messages, Web pages with the
mark• Pursue all impostors – actively seek reports of
phishing
Public Education
Use digitally-signed documents ONLYDon’t release unsigned documentsGet consumers used to idea that an unsigned
document is an untrustworthy document Use public education campaigns
“No one will ever ask you to confirm your password”
“Don’t believe alerts that address you as ‘Dear Customer.’”
