Steer clear of JavaScript packers

Paul Ducklin, Head of Technology for Sophos, a supplier of anti-virus software, says that developers of legitimate web applications should in future steer clear of tools for packing and encoding JavaScript. Ducklin is convinced that encrypting JavaScript code does more harm than good.

He said in his presentation, "The Malware in the Rue Morgue", at the RSA Conference that commercial packers like Aevita's Advanced HTML Encrypt and Password Protect gave hardly any protection against the theft of source code and web developers who thought they could effectively protect their creations against intellectual property theft using this or similar tools were on the wrong track. He demonstrated how source code encrypted with Aevita's tool could be converted into clear text within minutes using only freely available tools such as Mozilla's Rhino and Caffeine Monkey, along with his expertise in HTML and JavaScript."
