From Gawker hacks to Operation Payback denial of service attacks, are any sites immune to cyber threats? To help you keep tabs, Google on Friday announced that it will add notifications to its search results for sites that appear to have been compromised by a third party.

Going forward, suspicious sites - typically those affected by spam - will include a blue link below the title that says "This site may be compromised." Clicking on that link will direct users to a Google Help Center article that explains more about its notices. Clicking the main link will take you to the actual site.

"When a user visits a site, we want her to be confident the information on that site comes from the original publisher," Gideon Wald, a Google associate product manager, said in a blog post.

Wald said Google will use a "variety of automated tools to detect common signs of a hacked site." If it finds something, Google will add the link to its search results and contact the Webmaster of the site in question.

"Of course, we also understand that webmasters may be concerned that these notices are impacting their traffic from search. Rest assured, once the problem has been fixed, the warning label will be automatically removed from our search results, usually in a matter of days," Wald wrote. "You can also request a review of your site to accelerate removal of the notice."
