Hacked content detected on http://www.sina.com.br/

To: Webmaster of http://www.sina.com.br/,

Google has detected that your site has been hacked by a third party who created malicious content on some of your pages. This critical issue utilizes your site’s reputation to show potential visitors unexpected or harmful content on your site or in search results. It also lowers the quality of results for Google Search users.
Therefore, we have applied a manual action to your site that will warn users of hacked content when your site appears in search results. To remove this warning, clean up the hacked content, and file a reconsideration request. After we determine that your site no longer has hacked content, we will remove this manual action.


Following are one or more example URLs where we found pages that have been compromised. Review them to gain a better sense of where this hacked content appears. The list is not exhaustive.

Here’s how to fix this problem:

2    

Look for other compromised pages or files on your site

Be sure to check your entire site, including the homepage, for any unfamiliar content that could have been added. The malicious code might be placed in HTML, JavaScript, or other files on your site.
It can also be hidden in places you might overlook, such as server configuration files (e.g. .Htaccess file) or other dynamic scripting pages (e.g. php, jsp). It’s important to be thorough in your investigation.
3    

Use the Fetch as Google tool to isolate the malicious content

Because some pages can appear one way to a user and another way to Google crawlers, you can use the Fetch as Google tool to reveal some kinds of hacking.
Enter URLs from your site in the tool to see the pages as Google sees them. If the page has hidden hacked content, the tool can reveal that content.

4    

Remove all malicious content

You can also contact your hosting provider and ask them for assistance.
If you’re having trouble identifying and removing all the content on your site that is compromised, consider restoring an older backed-up version of your site.
5    

Secure your site from any future attacks

Identify and fix vulnerabilities that caused your site to be compromised. Change passwords for administrative accounts.
Consider contacting your hosting service to get help with the issue.
6    

Submit a reconsideration request

Once you fix your site, file for reconsideration to remove this manual action. Include any details or documentation that can help us understand the changes made to your site.
