If you use JavaScript to redirect doorway pages or for XSS you should always obfuscate your JavaScript code. That’s why I decided to post this really easy to use JavaScript Obfuscator. (It’s just a friendlier version of this one.)
To use it you just need to input your javascript (without the <script></script> tags!) and click in the “Encode” button. It will obfuscate your code with two similar methods so you can choose and then… well that’s pretty much it!
DISCLAIMER: It’s really easy to “break” the obfuscation for people with JavaScript knowledge, but at least it will keep away n00bs.
I just posted an obfuscation and deobfuscation module on my own site last night that I’ll be using in my XSS assistant, but I never thought about addition being used in the character values of the Javascript function. Looks like I need to add that to my code. Anyway, make sure to update me on how your article raper works so I can come up with a concept script for identifying the context of certain text in an article.
