WordPress site redirects to costabrava.bee.pl

I have just finished cleaning a wordpress website that had been hacked. The site would redirect to costabrava.bee.pl which is a malicious website.

Due to this Google began showing a warning page whenever someone navigates to that site, informing them that the site is infected.

I had to go through the site and locate all of the instances of code that looked like this:

eval(base64_decode("DQplcnJvcl9yZXBvcnRpbmcoMCk7DQokcWF6cGxtPWh

This code had been inserted in lots of the files on the site. It can be very time consuming to find the offending files. I cleaned the site by using Adobe Dreamweaver, downloading the whole site, including all the WordPress files, not just the theme files and ran a Find All for “eval” on the entire local site. From there I could see all the files that had the offending code and I was able to delete them and re-upload the cleaned file.

Obviously, cleaning the site isn’t the only thing that needs to be done, change all your passwords for the site and ensure they are very secure. Also make sure your WordPress is up-to-date and any plugins you are using.
