Facebook leaked your personal data?

Third-parties would have had access to personal information such as profiles,photographs and chat,and could have had the ability to post messages,the security software maker said.

We estimate that as of April 2011,close to 100,000 applications were enabling this leakage,the blog post said.

Over the years,hundreds of thousands of applications may have inadvertently leaked millions of access tokens to third parties,posing a security threat,the blog post said.

The third-parties may not have realized their ability to access the information,it said.

Facebook,the world8217;s largest social networking website,was notified of this issue and confirmed the leakage,the blog post said.

It said Facebook has taken steps to resolve the issue.

Unfortunately,their Symantec8217;s resulting report has a few inaccuracies. Specifically,we have conducted a thorough investigation which revealedno evidence of this issue resulting in a user8217;s private information being shared with unauthorized third parties,Facebook spokeswoman Malorie Lucich said in a statement.

Lucich said the report also ignores the contractual obligations of advertisers and developers which prohibit them from obtaining or sharinguser information in a way that violates our policies.

She also confirmed that the company removed the outdated API Application Programming Interface referred to in Symantec8217;s report.

Facebook has more than 500 million users and is challenging Google Inc and Yahoo Inc for users8217; time online and for advertising dollars.
