In a high-profile breach on the Facebook site, the fan page of Mark Zuckerberg – the founder of the popular social networking site – was hacked on Tuesday. Zuckerberg’s fan page breach came close on the heels of the Sunday hack French President Nicolas Sarkozy’s wall, with a hacker posting a message that the president will not run for re-election.

The message on Zuckerberg’s page said: “Let the hacking begin: If Facebook needs money, instead of going to the banks, why doesn't Facebook let its users invest in Facebook in a social way? Why not transform Facebook into a 'social business' the way Nobel Price winner Muhammad Yunus described it? http://bit.ly/fs6rT3 What do you think? #hackercup2011?”

Facebook, which has often been scrutinized about its handling of the private data information of its over 600 million users, soon removed the message from Zuckerberg’s page; though not it had received over 1,800 “likes.”

The response to Zuckerberg’s page hack has led the social network to announce a couple of new security measures – an HTTPS login which enables users to visit Facebook on a secure connection; and “social authentication.”

In a recent public announcement, Facebook said that the HTTPS login will be gradually rolled out “over the next few weeks,” thereby enabling the users to soon turn this feature on in their Account Settings.

Meanwhile, the “social authentication” – taking cue from security measure CAPTCHA – involves the tapping of the users’ social network before they can log on, and a cross-examination about who they know.
