Dec 11 2007 - Matt Heaton Blog’s has been cleansed. ATM he’s using latest version of WordPress (2.3.x). And also most of the blogs lists in this articles has been upgrade.

Jan 26th, 2008 - Seem like bluehost engineer did a bad job at cleaning, the goro spam is back.

Just after the recent issue on wordpress.com.cn now there is new wordpress imitater. A remote spamware injection by wordpress.net.in

I was reading one of Matt Heaton posted 2 days ago when I found bunch of spamsware link on his wordpress footer.

Matt’s is using default wodpress theme (kubrick) with single javascript for adsense. The only way the spams can get in is probably via php injection or by manual editing. All the spamware is redirect to howardowens.com/?order=XX page.

Lookup for howardowens.com

The below diagram explained the lookup results for howardowens.com. click on the image to enlarge.

Surprisingly the spammer website is also host by bluehost.com (69.89.16.0/20,74.220.192.0/19 ,69.89.16.4 -> box183.bluehost.com).

Tracking the spam sources.

Live example wordpress.net.in injection

Google query for warning “[function.include]” allintext: “wordpress.net.in” . Used fiddler or any http-inspector to trace the full header request.

• jean-cyril.com - wp-includes · spams link redirect to www.901am.com/?page=2157. jean-cyril.com has wp-info.txt inside his wp-includes directory. This text files hold unserialize database password and stuff.
• floaridablog.org - wp-includes · spams redirect to communications.uml.edu/sunrise/?id=1076 (University of Massachusetts Lowell) the offending spams page has been removed by UML maintainer.

Hiding from search engine Spiders

First, I did some more comparative search at archive.org for howardowens.com and mattheaton.com. It turn out both of this sites has been stop from IA Archiver few months before the spams start showing on their footer. You will need to check howardowens index on archive.org so you can understand my suspicious.

• http://web.archive.org/web/*/http://www.howardowens.com
• http://web.archive.org/web/*/http://www.mattheaton.com

Out of boredom I cloaked myself as the following agents.

• Mozilla/5.0 (compatible; Yahoo! Slurp; http://help.yahoo.com/help/us/ysearch/slurp) - 74.6.8.125 - llf520032.crawl.yahoo.net
• Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html) 66.249.64.50 - crawl-66-249-64-50.googlebot.com
• Mozilla/2.0 (compatible; Ask Jeeves/Teoma) - 65.214.44.204 - egspd42002.ask.com
• Mediapartners-Google/2.1 66.249.73.213 - crawl-66-249-73-213.googlebot.com

Not much change on both of these sites. Then I read the status header, it return 404 instead of 200. Nice tricks for stopping crawler & spider from spying their joy-ride-spamhouse.

Summary

bits & bytes from this accident we knew that

• Most of the site inject are running on wordpress 2.0.6 & below
• allow_furl_open is set to true for this injection to work
• Most of the blogs owner is unaware about the spams links (cloacking)

Checkout Murray access log, it will give you some ideas with the remote injections methods.

Update

Dec 03 2007

All the spams link to howardowens.com page has been removed. I havent talk with howardowens but I assume howard’s site is being injected the same way like Matt Heaton blog.

Dec 04 2007

Mattheaton.com has a minor update, the spams now inject on both header and footer.
tangonoticias.com:7070/d_pill/577.html.
As tangonoticias.com is running on Joomla CMS they create a static “Wordpress” on port 7070 (Real Network Server & RSTP Port). This is probably a work of different attacker, taking advantage of Matt heaton blindspot. Google Cache (Nov 12)

Dec 11 2007

Matt heaton has been purified. He’s now using latest version of Wordpress (2.3.1). You can still view it on cached thought & screenshot.
