Last night a friend of mine called me and explained what happened to one of his site. As a good friend I researched the issue and solved the problem.
This might be useful for anybody who had problems with “YUZO Related Posts Plugin”.
Yes, if your site has been hacked and you see strange redirects to Hellofromhony.org …. I can tell you that you are using “YUZO Related Posts Plugin” in WordPress…. and you will find a solution on this page.
The vulnerability allows hackers to inject code in vulnerable sites, which they later used to redirect incoming visitors to all sorts of scams, sites peddling malware software, and simply spammy pages showing ads.
If you have any technical skills you could just do it yourself by following these steps:
- Disable plugin and delete it from the server
- Got phpMyAdmin
- Search for Yuzo tables at wp_options
- Delete all of them ( 5-6 of them)
- Delete Yuzo table from the database index
- Check siteurl at wp_options (first row), it should be your site, if you have a redirect there will be something like hellofromhony.org/blabla
- Change that to your site’s URL.
- If you have more sites on the server using WordPress, check all of them, even if they did not install Yuzo plugin.
If you dont want to deal with it you can hire me to clean the site. Please contact me at email@example.com
More details about Yuzo plugin problems

Hackers can scan your web site and find which plugins are installed. On the other side they have a list of weak and vulnerable plugins. If they match, you are hacked.
The yuzo-related-post plugin has an unauthenticated cross-site scripting bug. As well, some other vulnerabilities have not been fixed — this was the deciding factor in why the WordPress team closed it.
