My site was hacked and so many porn related keywords drive traffic to my site. When I open the cached version of my site (cache:http://pennystockglobe.com/), and I tried to open it in pagewash(http://www.pagewash.com/nph-index.cgi/010110A/uggc:/=2fcraalfgbpxtybor.pbz/), I found that so many spammy porn related keywords in the footer and it linked to pages I've never made before, such as http://pennystockglobe.com/index.php?category=47&watch=996 (and those pages were indexed by google). When I open those pages in browser, it opens as usual. But if I open the cached version, there are full of sex related keywords on my page.. What happened to my website. And what should I do now to fix this problem? Thanks.
you should clean it manually or hire a professional for this purpose to clean your website before you get penalized from google
A common problem caused a lot of times by SQL injection. People exploit forms in websites to inject code into the website. If you have a form that is exploitable that could be how they did it. Rather it be a login form or a contact form. This is just one way hackers exploit websites and inject spam... Look at any scripts or code your website is running make sure they are updated. Look for security related information for the script or code that is running on your website. If you wrote it yourself then you need to look at your code...
