URGENT: If Your WordPress Blog is Acting Strangely, Follow These Steps

I checked my blog and the URLs looked malformed, with the following structure: http://www.whoisandrewwee.com/2009/09/03/unlocking-unconventional-traffic-sources-for-affiliate-campaigns/%&(%7B$%7Beval(base64_decode($_SERVER%5BHTTP_REFERER%5D))%7D%7D|.+)&%/#comment-506929

If you notice something similar or weird with your WordPress blog, you might want to take the following steps:

  • Check the “users” tab from the WP admin interface
  • Remove any unfamiliar users, esp those marked as “administrator”
  • To prevent users from registering, I’d go as far as to remove wp-register.php (keep a backup and FTP it back in if you have problems)
  • Check all of WordPress’ PHP scripts, remove global “execute” privileges

Once you’ve secured the perimeter, look at the “Settings” and “permalinks” tab.

If you see some weird stuff like “%&(%7B$%7Beval(base64_decode($_SERVER%5BHTTP_REFERER%5D))%7D%7D|.+)&%/#comment-506929”, you’d want to clear that, and replace it with your original permalink structure, or look it up on the WordPress codex.

You can also check out this other blog post for more details.

Note: this issue seems to be affecting WordPress 2.6.x. Not sure to what extent it’s affecting version 2.8.x.

UPDATE: Matt Mullenweg from the WordPress development team has posted about the security issues if you’re using an older version of WordPress. Here’s a WP support forum write up about what might be happening.

You might want to upgrade to a newer version of WordPress. Just take note that some of your plugins/themes might not work if the developer hasn’t updated the plugin for compliance with the newest version.

    We got it, too. Is this a world wide problem? I googled the change script and it seems a few similar problems have popped out recently.

    Thanks so much Andrew, my blog was also similarly affected and I’ve followed your instructions to fix the issue. I’d have been completely stumped without this post.

    Wonder if they’re targeting online marketers, the rotters?!

    Andrew – a colleague also affected has just told me that most people affected will also have had a new admin inserted directly into their SQL database that doesn’t show up in WordPress interface.

    I found this had been placed into my SQL db, it has obviously been stored for later foul internet deeds to be performed…

    Hi Kirsty,
    Thanks for that. I’ll drop a note to my server admin.

    For those who’re using fantastico/cPanel, it should be an easy fix from the “mySQL database” or “phpMyAdmin” consoles.

    Lots more going on beneath the surface! Permalinks and hidden admin users! This blog post worked for me to clean house: http://blog.nachotech.com/?p=125

    I also renamed my xmlrpc.php and wp-register.php files as a stop-gap solution. It seems 2.8.4 blogs are safe so far. I am guessing 2.8.5 will be out ASAP to correct this is 2.8.4 doesn’t.

    Can one with no security, no lien and no warranty want to
    get a company loan? No, if the customer goes through typical channels.
    However when he has none of these, it is a typical circumstance.
    There is an escape for the borrower: unsecured company loans!
    Right here, you are not required to offer all these lawfully legitimate files.
    Rather is it your business need that is taken into consideration for your loan application to be considered.

    long-lasting techniques of a company. They are, by nature, buoyed up by not having extremely precise repayment clauses.
    Nor are they handicapped by having pay-by-date. Wait till your business sees a significant improvement and then begin paying.
    Just do not take all your life. Little companies can take the loans to take care of short-term uses and
    pay back whenever there is money enough to pay back.

    So if you want a perfect example of exactly what business use viral
    marketing, look them up on youtube or just log into your facebook.
    Chances are you have actually seen them being
    circulated from buddy to pal on Facebook, Twitter and even through
    your email.

    knows how to get the word out will certainly help speed up the procedure.

    It’s likewise useful to inform all of your close friends, family members, and any individual who will listen that you have a great piece of home for sale.

    marketing. You have to concentrate your market very specifically in order to construct much targeted
    potential customers. Much like if you are targeting sport market, which sport are you targeting?

    like female’s tennis and so on.
