Microsoft Research creates a JavaScript malware scanner

Keeping JavaScript based malware at bay might just be a job for an AI-trained tool called Zozzle.

JavaScript is useful but the need to guard against malware hiding in deeply obsfucated code is a growing problem. Microsoft Research has invented a scanner that can detect malware using mostly static analysis - and has called it Zozzle.
Zozzle is a product of AI techniques. The researchers used a statistical classifier to scan millions of web pages for malware. The JavaScript has to be de-obfuscated first and then analysed for features that are characteristic of malware. The features are created using an abstract syntax tree. Zozzle hooks into the JavaScript engine to get the final expanded version of the JavaScript code the page contains.
