One of my blogs was hit today (Happy Halloween) by this new strain of WordPress Blog attacks.  The Sucuri Team was able to tackle the infection without issue and has posted some good information on the latest version attacking (at this point) Godaddy servers.  Read more below:

“Just a quick update to this blog post: More Attacks – insomniaboldinfocom.com.

We posted a few days ago that attackers were using insomniaboldinfocom.com to spread malware to multiple web sites. Today, they changed domains and are targeting GoDaddy sites usinginsomniaboldinfoorg.com.

The following domains/IP addresses are being used to spread the attack:

http://insomniaboldinfoorg.com/ll. php?k=1

www3.hope-soft57. net
www3.new-protectionsoft23. in
www4.free-pc-protection9. in

http://insomniaboldinfocom.com/mm. php

http://insomniaboldinfonet.com/mm. php

www3.large-defense1. in

All the sites we’ve seen so far have the following code added to all PHP files:

$_8b7b="\x63\x72\x65\x61\x74\x65\x5f\x66\x75\x6e\x63\x74\x69\x6f..
\x6e";$_8b7b1f="\x62\x61\x73\x65\x36\x34\x5f\x64\x65\x63\x6f\x64\x65";..
$_8b7b1f56=$_8b7b("",$_8b7b1f("aWYoZnVuY..

Which is basically just the eval(base64_decode encoded. What is interesting is that this site is hosted at 77.78.239.53, which was used on previous attacks by the “Hilary Kneber” group, so we think they are all related:

myblindstudioinfoonline. com
meqashoppercom. com
insomniaboldinfocom. com

The following script should clean up any infected site: http://blog.sucuri.net/2010/05/simple-cleanup-solution-for-latest.html

wordpress threat detectedMany of you over the past few months have experienced the onslaught of WordPress attacks which has plagued site owners – and loyal fans, alike.  I maintain multiple WordPress blogs in addition to our beloved She-geeks.com site, as well as my clients’ WordPress blogs.  While refraining from too much detail, I had the unfortunate duty of ridding two such WordPress websites of these WordPress attacks.  While both of the blogs I’m referring to maintained updated software (plugins and core files), they still fell victim to these attacks.  The attacks I am referring to primarily affected PHP pages, which would mean that A LOT of sites out there on the internet had the potential for infection.  The code would essentially insert itself into each PHP page on your site and/or WordPress blog and add strings of code which contained “eval(base64_decode“ in some way, shape or form.  This script is generally found at the very top of the page’s code – I assume so it hits first.

I spent hours upon hours working to isolate the issues and hand-remove the malicious code only to have it reappear a week later.  I ultimately had to bring on the “big dogs” in WordPress blog security, Sucuri.net.  David and the rest of the Sucuri Crew were able to solve all site issues within 30 minutes.  It was a beautiful thing.  You see, although I managed to remove most of the “malicious eval code” during these attacks myself, there appeared to be a snippet of code eluding my capture.  This code, also referred to as a backdoor by many, was hiding in the shadows of unending lines of code.  Its really too much code to parse through with the naked eye…nevermind the fact that manual removal like that is likely not the most efficient method when time (and money) is of the essence.  What can I say, I was stubborn.   Needless to say, the Sucuri Crew was very efficient and truly a life saver on that day.

Below I’ve outlined some of what I found online pertaining to the malicious attacks as well as some portions from my personal experience with the nefarious code.

Some of the malicious strings of code which were present:

“http://holasionweb dot com/oo dot php”

holasion web

There are a few mentions of solutions you can try but, in the end, the only solution which seemed to work in my case was enlisting Sucuri’s help.  However, I’ll list a few better known solutions for this type of WordPress attack:

  1. completely deleting your WordPress install and reinstalling on your hosting account (note: not fun)
  2. logging into your hosting provider and accessing an CLEAN archive version of your website. (note: you’d need to know an archived date in which your blog was completely clean and free of the bad code)
  3. Sucuri offers a free “cleaning” script which you can run yourself and seems to have helped quite a few people resolve their issues

Additional documented information which may prove useful for others is shown below.  You may see some similarities.  If you’ve collected any additional information or have a similar story to share, we’re all ears.
