Can you block backlinks from another domain

[phatride]

Wondering if this is somehow possible. A site got hacked and created a /data folder with hundreds of .php files that are web pages selling all sorts of stuff.

We deleted the /data folder and blocked Google from indexing it.

Just noticed in Webmaster Tools that the site has 35,000 backlinks from other sites that got hacked with the same way.

Is there a way to block these sites? I am assuming there isn't, but wanted to see if anyone ran into the same problem.

It is a wordpress site is that helps.

I am not clear on your question.

It sounds like your site was hacked and new web pages were added to your site. You discovered the problem and removed the added pages, thereby removing the links they created.

When you ask "Can you block backlinks from another domain", who owns the domain which have the web pages with the links? When you ask to "block" the links, block how? from whom?

My best guess is you are worried about being hacked again by the same group. It sounds like you have blocked the /data folder in robots.txt so if the same group hacked your site in the same way, the pages would not be seen or crawled by Google nor Bing since you have it blocked. If they used a new directory, that solution would not work. The best approach is to upgrade your site's security and have it tested. Change all passwords, etc.

When you're running Wordpress, the best way you can "block" these sites, is to keep updating wordpress as new updates roll out. I think you mean that by: block these sites.

They're sites from hackers who hack old Wordpress sites that have known vulnerabilities. Updating your site will solve that issue, as that's one of the things that gets fixed when you update your core files.

Hope this helps.

Both Ryan and Yannick have good answers here. In addition, if you get a notice from Google in your webmaster tools or seem to have a penalty, you might file a reconsideration request and let Google know you were hacked but now have everything cleaned up.

If you look online, you can find several resources that help to keep your Wordpress site from being hacked and test its security.
