If I was a victim...

If you were a victim of BlackSEO attacks you have a lot of work waiting for you.

Of course, you should delete all non authorized contents, but that may be not enough.

If your site was compromised, you need to fix the security problems that mad it possible.

Take into account that attackers could have put some backdoors to give them acces to your systems in the future. Look for them, checking both for modifications in your files and files maliciously created. Having a listing of authorized files with their hashes could be a great help.

Don't forget to look for modifications of your search engine related files, like "robots.txt" or sitemaps.

But even deleting contents, fixing security problems and getting rid of every backdoor is not enough. Search engines will keep showing undesired results for your site. Use the webmaster tools they provide to remove every result you don't want them to display.

And, when everything is OK... keep working on the security of your systems!
