Sophos has posted a blog entry about a flaw on Facebook’s user data.

The author of the article, Graham Cluley, writes that he found a found a flaw that lets him see a user’s birthday even if the user chose to hide his or her birthday to the public. He has posted a video in Youtube which shows how this flaw can be exploited.

He asks his readers to enter a fake birthday instead of their real one because Facebook only uses it to check if they are an adult and that it can help prevent identity theft.

Facebook has fixed the problem according to the blog entry.
