WordPress Websites Redirecting to buyittraffic[.com], cuttraffic[.com] & puttraffic[.com]- Resolve Now
WordPress sites have yet again become the victim of a widespread redirection malware. A lot of WordPress web owners contacted us worried about their websites redirecting or admin panel throwing an error.
While doing the cleanups on these websites, we could draw similarities in their hacking fashion. All these websites happened to have been infected by the same redirection malware. This malware redirected them first to a malicious domain by the name buyittraffic[.com] and then finally to a domain named cuttraffic[.com] or puttraffic[.com] or importtraffic[.com] or gianttraffic[.com].
In many cases, we are also seeing websites to redirect first to clicks.worldctraffic[.com], top.worldctraffic[.com], red.toupandgoforward[.com], bluelabelmoscow.[com] or ticker.trasnaltemyrecords[.com] before landing on one of the above sites.
It is a typical example of malware redirection ‘chains’. Where websites get redirected multiple times before landing on the desired domain.
On further investigation, a few hundred websites seem to be infected with this malware now:

The homepage redirecting to other domains is, obviously, a tell-tale sign of the hack. However, there are other signs as well, attached to this malware. You can tell you are hacked, if:
- you are unable to access the website.
- you are unable to log into your wp-admin panel.
- your wp-admin throws a 404 error.

“ERROR: There is no user registered with that email address”.

Technicalities Behind the Hack
I have already mentioned how this malware redirects your website multiple times. Let’s see how this happens:
The following image is from one of the hacked sites that came to us. Notice the domain name.
Now, when I try closing the notification bar on this domain, it redirects me to a slight variation of the same domain – 0.cuttraffic[.com].
If I cross the notification bar yet again, it redirects to 1.cuttraffic[.com] and so on.
A quick inspection also confirms the injection of the link buyittraffic[.com] in the site.
Moving on. We are also seeing the redirection page customize itself according to the regional languages of websites. See picture below:
How hackers infected your site?
Coming to the question of how hackers were able to infect so many websites.
The reason is not that apparent but we suspect that a vulnerable version of adminer could be the reason.
While doing the cleanups, we were able to find adminer.php file in the root folder of all the affected websites. It is, therefore, safe to assume that the hackers use adminer script to access and infect the database.
Combining the above information with the fact that adminer versions prior to 4.6.3 has a serious vulnerability. This vulnerability allows attackers to read local files on the server, such as wp-config.php on WordPress, local.xml on Magento, etc. These files contain the database credentials that could be used to access the database.
Thus, we recommend that you check for adminer.php file on your server and remove it.

What You Can Do About the Hack?
You realize your website is infected, now what?
Two things: You can either get professionals to clean your website. Or you can attempt to clean the website manually on your own.
For the latter option, you can start by checking your server for malicious files. Know that hackers usually exploit multiple vulnerabilities and create malicious files on the server. You will have to hunt for the infected files. Then remove precisely the bits that are triggering the redirection. Few key places to look for malware causing this infection:
- Look for adminer script: Log into your cPanel/FTP of the website and look for a file named ‘adminer.php’. Usually, this file is deployed by hackers to leave a backdoor access to the server. If you find this file, delete it immediately.
- Locate this backdoor: In cases like these we’ve often located a suspicious file at wp-content/force-download.php. Be sure to check if you find force-download.php file under wp-content folder of your WordPress. If you do, delete it.
- Check source: This is one of the most basic checks you should do, check your index page’s code and search for these malicious links. If you find them, please remove them.
- Check for Fake users: Go to the wp_users table of the database and verify no unknown and unauthorized users are there. With an intention to retain access to the attacked sites, hackers create fake admin accounts in them. This we also saw in this attack. Most infected sites that came to us have had malicious users/admin created in them.
Several known fake user IDs used in these attacks are testing@gmail[.com], firstname.lastname@example.org[.]com (username: wordpresdadmin)
