Pretty much everyone agrees now that search engines CAN read JavaScript.
Code:
<script language="javascript">
<!--

document.write(unescape('%3C%6C%69%6E%6B%20%72%65%6C%3D%22%63%61%6E%6F%6E%69%63%61%6C%22%20%68%72%65%66%3D%22%68%74%74%70%3A%2F%2F%65%78%61%6D%70%6C%65%2E%63%6F%6D%2F%77%6F%72%64%70%72%65%73%73%2F%73%65%6F%2D%70%6C%75%67%69%6E%2F%22%3E'));
//-->
</script>
Assuming you are right that text substitution is being used -- how are you going to read and substitute this? If you are a secret-agent you could grep and decode somehow i suppose -- what does this say -- just run the code in phantomjs. That is the way i might scrape the page. if you broke the JS code with + maybe it might fool the substitution but if you really want to get down to it
echo or cat (<input>)|sed 's/\n//g' then ....
Code:
echo '<script>if(window.location.href.indexOf("yourd"+"omain.com") < 0) { window.location("http://yourd"+"omain.com"); }</script>'
|egrep -o ".{0,20}\(window\.location\.href.{0,20}"
|sed 's/window/you are fucked now/g'
<script>if(you are fucked now.location.href.indexOf("yourd"+"om
fuckup the frame breaker JS
Sure as fuck won't hurt
