Microsoft Develops JavaScript Malware Detection Tool

Filed under: — By Aviran Mordo @ 4:09 pm

As browser-based exploits and specifically JavaScript malware have shouldered their way to the top of the list of threats, browser vendors have been scrambling to find effective defenses to protect users. Few have been forthcoming, but Microsoft Research has developed a new tool called Zozzle that can be deployed in the browser and can detect JavaScript-based malware at a very high effectiveness rate.

Zozzle is designed to perform static analysis of JavaScript code on a given site and quickly determine whether the code is malicious and includes an exploit. In order to be effective, the tool must be trained to recognize the elements that are common to malicious JavaScript, and the researchers behind it stress that it works best on de-obfuscated code.
