Detecting Malicious JavaScript Code in Mozilla
The JavaScript language is used to enhance the clientside display of web pages. JavaScript code is downloaded into browsers and executed on-the-fly by an embedded interpreter. Browsers provide sand-boxing mechanisms to prevent JavaScript code from compromising the security of the client’s environment, but, unfortunately, a number of attacks exist that can be used to steal users’ credentials (e.g., crosssite scripting attacks) and lure users into providing sensitive information to unauthorized parties (e.g., phishing attacks).
