A Web site uses a behavior monitor that operates as a gatekeeper for a browser. The attack injects Web content with malicious executable code that executes on an end user device when the code executes in a browser on the device. A message is received at the monitor from a browser for retrieving Web content; the browser executes on a computing device having sensitive information. The Web content is retrieved from a target Web server and analyzed for XSS. If found, the destination to which some or all of the sensitive information will be sent if the XSS executes is determined. A message is displayed in the browser regarding whether the Web content that was requested should be viewed in the browser. In this manner, execution of the XSS in the browser is prevented. The analyzing and determining steps are performed before the Web content is received by the browser.
